What Time of Year Do Pine Trees Drip Sap (and Can I Stop It?)
Pine trees wow with their array of colors–jade needles, chocolate-brown cones and hickory-colored bark. And for a short time of the year, some pines add yet another hue: shiny, gold sap.
But how much pine sap is too much? Or what if instead of dripping liquid gold, your pine tree’s sap is white?
Keep reading for everything you need to know about when pine trees drip sap, signs it might be a problem and how to help your tree.
Pine Sap: When It Happens, How It Should Look and What You Can Do
What time of year do pine trees drip sap?
Because sap is like the engine that keeps nourishing ingredients running throughout the tree, small amounts of sap may ooze all year from pines. Usually that happens after they’re pruned, when they begin budding or as the seasons change.
Typically, you’ll see the most sap flow in spring and early summer.
During winter, sap slows down and then picks back as spring approaches. Plus, as the temperatures change from cool to warm, the pressure increases, which can force a bit of sap to drip.
How much pine sap is normal? What is considered excessive pine sap?
You can expect to see a few drops here and there during the growing season, or shortly after the tree has been pruned. But if the sap is pooling or puddling, that’s too much.
An excessive amount of sap is often paired with other symptoms like:
- Multiple holes in the tree’s trunk that look like they’re made by an insect
- Broken or damaged branches
- Wounds from a pruning cut
- Dead sections of bark on branches or the trunk (called cankers)
- Sap that’s not golden-brown in color
What if I have a pine tree oozing white sap with a white substance on the tree?
Golden sap comes from healthy trees. If you see any other colored fluid, your tree could have a pest or disease problem. So, your best bet is to have a certified arborist examine the tree in person and see what’s up.
Three common culprits are…
- Pine bark aphids (also called pine bark adelgids). These insects feed through tree trunks, leaving tiny holes of white sap that can make the whole tree look whitewashed.
- Cytospora canker. This disease attacks stressed evergreens, causing brown needles, dead branches and dead bark that oozes a white sap.
- Zimmerman pine moth. Caterpillars of this common moth tunnel under tree bark, which causes golf ball-sized masses of sap to form on the tree’s trunk.
Anything I can do to make a tree stop sapping or stop tree sap from running?
Again, a pine dripping a bit of gold-colored sap is healthy, so just let nature take its course.
But if that’s not the color of your tree’s sap, click below to figure out the problem (and pinpoint a solution).
Pine Tree Sap Season: Pine Tree Sap Uses And Information
Most trees produce sap, and the pine is no exception. Pine trees are coniferous trees that have long needles. These resilient trees often live and thrive at elevations and in climates where other tree species cannot. Read on for more information about pine trees and sap.
Pine Trees and Sap
Sap is essential to a tree. Roots take up water and nutrients, and these need to be spread throughout the tree. Sap is a viscous liquid that carries nutrients throughout the tree to the areas where they are most needed.
Tree leaves produce simple sugars that must get transported through the tree’s fibers. Sap also is the means of transportation for these sugars. Although many think of sap as a tree’s blood, it circulates through the tree much slower than blood circulates through the body.
Sap is mostly made up of water, but the sugar compounds it carries makes it rich and thick – and prevents freezing in cold weather.
As to the sap in pines, there really is no pine tree sap season. Pine trees produce sap all year long but, during the winter, some of the sap leaves the branches and trunk.
Pine Tree Sap Uses
Pine tree sap is used by the tree to transport nutrients. Pine tree sap uses include glue, candles and fire starting. Pine sap is also used for making turpentine, a flammable substance used for coating objects.
If you use a knife to harvest sap, you’ll find that pine tree sap removal is not always easy. One way to attack pine tree sap removal from your knife is to soak a rag in Everclear (190 proof) and use it to wipe the blade. Find other tips for removing sap here.
Excessive Pine Tree Sap
Healthy pine trees drip a little sap, and it should not be a cause for concern if the bark looks healthy. However, sap loss can damage the tree.
Excessive pine tree sap loss results from injuries like broken branches in a storm, or accidental cuts made by weed whackers. It can also result from borer insects who dig holes in the tree.
If the sap is dripping from multiple holes in the trunk, it is likely borers. Talk with a county extension service office to find the right treatment.
Excessive sap can also result from cankers, dead spots on your pine caused by fungi growing under the bark. Cankers can be sunken areas or cracks. There are no chemical treatments to control canker, but you can help the tree by pruning out affected branches if you catch it early.
It’s not uncommon for certain types of trees to drip sap. The hardwood maple, for example, is known for its sweet and savory sap, which is used to make syrup and sweeteners.
The softwood pine also produces sap, though it’s more bitter and not intended for human consumption.
Whether you have a maple, pine or any tree dripping sap on your lawn, though, you might be wondering how to stop it.
Prune the Tree
In some cases, you can stop a tree from dripping sap by pruning it. Using a pair of sharp gardening shears, cut off any small branches that are dripping sap.
It’s recommended that you prune trees during the spring or fall. When done during the summer or winter, pruning may stress the tree or even kill it.
So, wait until the spring or fall to prune any trees in your landscape that are dripping sap.
Apply a Pruning Sealant
Pruning alone won’t necessarily stop a tree from dripping sap. If you simply cut off a branch that’s dripping sap, the tree will likely continue to drip sap from the area where you cut it.
There’s an easy solution for this problem, however: pruning sealant. Available at most home improvement stores, pruning sealant is used to seal wounds on trees. It’s available in both spray aerosol cans as well as brush-applied liquid.
Using either type, you can seal the parts of the tree where you’ve pruned branches. Once the pruning sealant has dried, the tree won’t be able to drip sap from the areas where you pruned it.
Apply an Insecticide
It’s also a good idea to use an insecticide on any tree that’s dripping sap.
Why is this necessary?
Well, countless pests feast on the nutrient-rich sap. And if you allow these pests to go unchecked, they’ll bore deep holes into the tree, causing it to drip even more sap.
Neem oil is an excellent, safe and all-natural insecticide that works wonders on trees. Just spray a solution of diluted neem oil over the tree, at which point it will remain protected from most common pests.
Aside from pruning, sealing and using an insecticide, there’s not much else that you can do to stop a tree from dripping sap. Rather, you should remain patient while waiting for the tree to stop dripping.
Assuming you’ve pruned the dripping branch or branches – and you’ve applied a pruning sealant over the newly created wounds – it should stop dripping sap eventually.
In the meantime, consider removing any outdoor furniture or accessories underneath the tree so that they aren’t exposed to the sap.

Tapping the Pine Tree… Plant Resins and their Uses
I avoid saying that I love trees. That sems too trite, and it sounds blasé… because everyone “loves” trees; it says so on their t-shirts. So I choose other words like fascinated, inspired, excited. To me, there really is something magical and spiritual about walking through a forest filled with trees that are hundreds of years old. There is a sense of life that permeates the air in even the stillest of forests. There is a fair amount of quality research being released in recent years about how trees communicate. Yes, trees actually do communicate with each other in the forest although I have not seen any credible evidence for sentience in trees, and maybe this is really a topic for another article. Ultimately, I believe that there is a point of balance between using trees for our benefit and treating them with respect. I have no problem with utilizing the products that trees provide us. Trees can truly provide a sustainable supply of many things useful for humans. Trees can even be part of a regenerative agriculture, where the air, water, soil, and ecology as a whole are improved while we still collect a harvest. But if we do not respect the trees, and the ecology surrounding them, our endeavors will be destructive and degrading. Trees cannot be treated like so many things in our modern throw-away society.
With that said, there are so many products that trees provide, in their living and, yes, even in their dying. Most people are well familiar with the fruits and nuts that living trees provide. Dead trees provide firewood, building wood, and even food for certain medicinal and edible mushrooms. There are a number of trees that can be tapped to provide sweet sap that can be reduced to a tasty syrup. The most notable are the maple species, although there are actually a number of other species that can provide a good, but lower quality syrup than the maples.
I want to address another product that can be obtained from tapping trees, but it is not for their sap. It is for their resin. Resin is obtained from many trees other than the pines, but that is the most common resin-producing tree in my local Temperate Climate.
We see a pine tree and we think Christmas trees, pine cones, wood, and maybe paper. A few of us think about pine nuts… delicious! There are probably a few of us who think about a tea made from pine needles that is high in vitamin C and was used to prevent scurvy in long Winters without fresh fruits and vegetables. Those with some land may consider them as good trees for windbreaks. But how many of us see a pine tree and think of turpentine, rosins (for bowed string instruments, gymnists, ballet dancers, baseball pitchers, etc.), varnish, oil-paint thinner, furniture wax, lamp oil, soap, tar, and pitch?
In modern times, many of these products are now made with synthetic chemical processes that can be highly polluting and is typically unsustainable. As a Permaculturist, I am very interested in learning more about traditional products, their collection, processing, and uses. The remainder of this article provides an overview of the science, history, collection, and uses of resin.
Pine Resin is naturally produced from wounds on the tree.
Resin is a fluid (specifically, a hydrocarbon) that is secreted from certain plants (a.k.a. resinous plants), most commonly trees, and most commonly coniferous trees such as pine trees. Resins perform a number of functions in the plants that produce them. Resins seal over wounds, and this protects the plant from pests and infections. Resins contain antimicrobial properties that help prevent decay and fungal infections, and resins also seem to decrease water loss during droughts or plant injury.
Humans have gathered and used resins from plants for thousands of years. Resins have been used for waterproofing, varnishes, adhesives, art, incense, medicines, and many other purposes. It is only recently in human history that we have started using synthetic, as opposed to natural/plant-derived, resins.

Another pine resin collection device.
Resins can be collected by tapping trees. This has traditionally been achieved by notching the bark in a parallel V-shaped pattern. At the lowest notching, a bucket collects the pooled resin. Trees can be tapped for well over 20 years, and are then used for other purposes including timber, since the wood is not damaged during the tapping process. Depending on the species of tree and the product desired, various processing techniques are used to refine the resin.
While all resinous plants produce resin, some species and hybrids produce higher quality resin than others. Trees also produce other fluids (e.g. sap, latex, gums, etc.), but these are chemically quite distinct from resin. Resins can be categorized a few ways, and while I think the following is a pretty good system, there is a fair amount of overlap between categories:
Hard Resins: These are, not surprisingly, hard. Here are some examples of hard resins:
- Dammar – obtained from the Dipterocarpaceae family of lowland, tropical rainforest trees from around the globe and the Agathis trees of southeast Asia and northern Australia. Dammar is used as a glaze for foods, crafts, incense, varnish, and more.
- Mastic – obtained from the Mediterranean Mastic Tree (Pistacia lentiscus). Mastic was commonly used as a natural chewing gum, but it is also used in ice creams, puddings, pastries, nougat, sauces, soups, fruit and vegetable preserves, soft drinks, coffee, liqueurs, and many other foods. It has a long history as a medicinal and incense, and is also used in perfumes and cosmetics and even in varnishes.
- Sandarac – obtained from the Sandarac Tree (Tetraclinis articulata) of North Africa in a dry, Mediterranean climate. Sandarac is used for varnish and lacquer.
Elemi resin ready to be harvested.
Oleoresins: These are resins that contain an oil component naturally made by the tree. They typically stay soft or gum-like. Here are some examples of oleoresins:
- Balsams – obtained from a variety of trees and shrubs. Balsams contain certain esters (e.g. benzoic or cinnamic acid) that are aromatic, and therefore, balsam is commonly used for as a fragrance and a traditional medicine.
- Copaiba – obtained from the Copaifera genus of leguminous trees of South America. Used in varnishes and lacquers.
- Elemi – obtained from the Elemi Tree (Canarium luzonicum) tree of the Philippines. Used in varnishes, lacquers, and traditional medicine.
- Labdanum – obtained from the Rockrose (Cistus species) from the Mediterranean. Used in traditional medicine and perfumes.
- High-Terpene Resins – obtained most commonly from Pine Trees (Pinus species). See Turpentine below for more detailed information.
Gum Resins: resins that are produced with a natural gum (sugars/polysaccharides) instead of oil. Here are some examples of gum resins:
- Frankincense – obtained from the Boswellia genus of trees from tropical Africa and Asia. Used as an incense, perfume, medicinal, and had many religious ties.
- Guggal – obtained from the Guggal Tree (Commiphora wightii) of North Africa and central Asia. Used as a traditional medicine.
- Myrrh – obtained from the Commiphora genus of tree of tropical Africa, Asia, and South America. Used as a fragrance and medicinal.
Amber with a trapped insect.
- Amber – the color “amber” is named after this amber-colored plant resin that has fossilized, although there is a blue amber that is stunning. Amber sometime contains animals or insects and is used in paleontology. Amber is used in jewelry, traditional medicine, perfumes, incense, varnishes, and lacquers.
- Copal – this is a resin that has not quite been fossilized yet, so it can be considered a resin that is on its way to become an amber. It has been used as incense and medicine and varnish.
The Loblolly Pine is commonly used for timber, phone poles, and paper, but is a high-terpene producing resin plant.
Many of the oleoresins from pine trees (and other trees listed below) have high levels of terpenes. Terpenes are a class of organic compounds (hydrocarbons) that a tree produces to repel pests; however, terpenes are produced and/or used in almost all living creature in the world. Some examples of natural products containing terpenes are steroids and beta-carotene. Once a terpene is altered, it is known as a terpenoid.
Turpentine is a fluid obtained by distilling high-terpene oleoresins. Collected oleoresins are placed into a steam distiller, and the turpentine is evaporated off and collected in a condenser. Turpentine can also be extracted via a process known as destructive distillation which occurs during pyrolysis (this is the process that occurs with the proper use of rocket stove technology). I can’t find a lot of information on obtaining turpentine through pyrolysis, but when I do, I will share it.
Turpentine can be used as a solvent (a substance that dissolves other substances) and to produce varnish. It can also be mixed with beeswax to make a high quaility furniture wax. Turpentine can be burned in oil lamps and can be mixed with ethanol to make “burning fluid”, an illuminant. Turpentine is mainly used today, once it has been processed, as synthetic pine oil. Pine oil is used for fragrance, flavoring, and in cleaning agents to give the “pine” odor.
Trees that have traditionally been primary sources of terpentine:
- Aleppo Pine (Pinus halepensis)
- Loblolly Pine (Pinus taeda)
- Longleaf Pine (Pinus palustris)
- Maritime Pine (Pinus pinaster)
- Ponderosa Pin (Pinus ponderosa)
- Scots Pine (Pinus sylvestris)
- Slash Pine (Pinus elliottii)
- Sumatra Pine (Pinus merkusii)
- Balsam Fir (Abies balsamea) – produces Canada Balsam. Used as a glue for eyeglasses, a traditional medicine, and in soaps and perfumes.
- Terebinth or Turpentine Tree (Pistacia terebinthus) – a very-long lived tree from the Mediterranean and Middle East.
- Larch (Larix species) – produces Venetian Turpentine. Used in varnish, traditional medicine, and traditional chewing gum.
- Red Spruce (Picea rubens) – produces Spruce Gum. Used as a traditional chewing gum.
Other Resin Products
Rosin (aka Colophony) – ROsin (not REsin) is the substance left over after turpentine is distilled from resin. Rosin is a solid and ranges in color from yellow to black. It is used by violinists and other string instrument musicians, in sealing wax, varnishes, medications, foods, and in electronic soldering.
Pine Tar – produced when heating Pine wood at high temperatures without catching fire (pyrolysis). Water and tar drip from the wood leaving charcoal behind. Used as a wood preservative and water sealant (boats, roofs, ropes, etc.) and in soaps and traditional human and veterinary medicines.
Pitch – Pine Tar is heated so that the water is evaporated. When the tar thickens, it is called pitch. Pitch was traditionally used for waterproofing seams and wooden containers (buckets, barrels, boats, etc.) and roofs. Some people consider Pine Tar and Pitch the same thing, others separate them based on consistency… Pine Tar being more liquid than Pitch.
Varnishing a hand-crafted wooden canoe.
Varnish – This is a protective “finish” or application for wood and other materials. Varnish is usually transparent or mostly transparent. It goes on wet and dries hard. It can have various levels of sheen (high gloss, glossy, semi-gloss, satin, etc.). Traditional varnishes contain an oil, a resin, and a solvent. The oils, also known as drying oils, harden after long exposure to oxygen. Examples of drying oils are linseed oil, poppy seed oil, tung oil, and walnut oil. Resins have been discussed at length above, and varnish resins include amber, copal, balsam, copaiba, elemi, mastic, rosin, and sandarac. The most common solvent, by far, is turpentine.
Lacquer – This is a type or method of varnishing, but is typically treated separately. Most varnishes undergo a chemical reaction that causes the varnish to harden. However, lacquers only undergo evaporation. If the solvent is reapplied to the finish (i.e. the lacquer), it will soften again. The resin that is traditionally used to make lacquer is lac (you can see where the name comes from!). Lac is the secretion from the lac insects of Asia. The dried secretion is refined and cleaned with a few different methods and then dries into shellac flakes. These flakes are dissolved in a solvent (lacquer thinners or alcohols) to make liquid shellac. Modern lacquer uses synthetics like polyurethanes, acrylics, or alkyds. Because these lacquers do not contain lac, they are not called shellacs, just lacquers. Another difference between modern varnishes and lacquers is that modern lacquers/shellacs are sprayed on while varnishes are brushed on.

What is Pine Resin and Why Do Trees Produce it?
Have you noticed, while walking among pine or other evergreens, that some trees exude a sticky substance? This is pine resin and is produced as a healing and protective measure when a tree is wounded.
The pine resin is antimicrobial and works to protect the plant from disease. Those same components can help to fight bacteria and fungus on our bodies, as well, making pine resin a great item for your home first aid kit.
My first experience with pine resin salve was a gift I received from Chris at Joybilee Farm. I happened to have a rash on the back of my ankle which was not responding to Plantain Balm, which I use frequently for skin irritations. The Pine Salve that Chris sent healed the rash with just a few applications. I was now on the hunt for pine resin so I could make my own.
But the pine salve is not just for rashes. It’s also an effective healing agent on cuts and bruises, helps to draw out splinters, and can be rubbed on your chest for congestion.
How to Harvest Resin
Pine resin is extremely sticky and not always easy to remove, so be sure to wear old clothing when collecting it. A glass jar that was headed for the recycling bin and an old butter knife are all that is needed to collect it. You’ll want to keep these items for this use only since they will be difficult to clean afterwards.
The resin is healing the tree, so your first consideration is to leave plenty for the tree after collecting. Use your knife to scape just the outer layer of resin from the tree. In colder weather, it may be hard and you may be able to break it off, rather than scrape it.
Tree Sap Remover
Rub some melted tallow, or other fat or oil, onto your hands to remove the pine resin. Then wash with soap and water.
Use alcohol to remove the tree sap from your clothing. Some scrubbing will be necessary, so again, it’s best to wear something old that you don’t have to worry about ruining.
You can see the pine resin dripping where a tree branch has been removed. Since there is so little resin here, it would be best not to harvest.
How to Make Pine Resin Salve
Pine resin is most commonly used, but you can also use spruce or fir resin.
Add as much olive oil as pine resin you’ve collected to your collection jar of resin. Place the jar of olive oil and pine resin in the top of a double boiler (or make your own double boiler).
Simmer very gently on the stove top until the resin melts. This may take several hours.
Strain through a fine mesh metal strainer and return to the double boiler. Clean the strainer with melted tallow or oil in the same way you removed the tree sap from your hands.
For every cup of resin/oil mixture, add 1/4 cup of grated beeswax, or beeswax pastilles. Heat on a very low setting, stirring until the beeswax has melted.
Pour the melted balm into tins or small glass jars and allow to cool.
Store the balm in a cool, dark place.

Pine tree dripping sap
It is difficult to know what this might be without photos or a sample. If the tree has been recently injured, it will excrete sap so look to see if the sap is oozing from a cut or injury. If the sap is coming from one specific area, it also may be an insect infestation so you can look for holes in the trunk. If the sap is pinkish in color, it could be pitch mass borer insect. If the sap has a popcorn-like appearance, it could be Zimmerman pine moth. If the sap appears to ‘rain’ from all different areas, it may be from new cone development and the excess moisture we had this spring. You can check to see if there is sap around all of the cones. Finally, the ‘sap’ may not even be sap but rather ‘honeydew’ which is excretion from aphids.
If you can provide several good, detailed photos, that would help. Or you can take a sample to the Diagnostic Clinic at Arapahoe County Extension Office at
5804 S Datura St, Littleton, CO 80120; Phone:(303) 730-1920. There is a small diagnostic fee for in-county residents. Make sure the sample you bring is at least 18″ long and is indicative of what exactly you are seeing on the tree.
Sap Dripping From Trees
Honeydew On Walkway Under A Tree
Do you have sap dripping from trees?
Many homeowners have trouble with sap dripping off of their trees onto their cars and walkways. This sticky substance can be difficult to remove, accumulate dirt, and attract flies and other annoying insects.
What most homeowners will be surprised to learn is that this sticky substance isn’t sap at all. The substance is Honeydew, and despite the name it has no relation to the fruit. Honeydew is the excrement of plant-sucking insects such as aphids, lace bugs, and certain types of scale. Deciduous trees do not drip sap from their leaves. If you have “sap” dripping from your deciduous tree it is honeydew and is a telltale sign of an insect infestation.
Insect infestations that lead to honeydew are frequently found on rose, ash, oak, elm, maple, willow, and fruit trees.
Oak Tree Dripping Sap:
Many homeowners ask specifically about their oak tree dripping sap. Oak trees are one of the species that are susceptible to the plant-sucking insects that create honeydew. They do not naturally drip sap. If you have an oak tree dripping sap get help from an Arborist.

Does Honeydew Hurt My Trees?
Honeydew by itself may be annoying and a hassle but will typically not hurt your tree. The real issue comes from the fact that a fungus called Sooty Mold will begin to develop on Honeydew.
Honeydew on Leaves
Sooty Mold: Is a fungus that coats the leaves of your trees to the point where they can no longer absorb sunlight. This means that the process of photosynthesis is interrupted and the tree will not be able to produce the nutrients they need for survival. If your trees and shrubs are turning black you most likely have a sooty mold problem caused by honeydew.
Treatment For Sap Dripping From Trees:
To keep honeydew and sooty mold from accumulating on your tree you must suppress the plant-sucking insects that create the sticky substance. To achieve this you have several options.
Prevention: Most insects are more likely to feed on stressed trees. Maintaining the health and vigor of your trees can help protect against an infestation of plant-sucking insects. You can maintain the health of your tree through routine pruning, bio-stimulant applications, and seasonal sprays.
Organic Control through Beneficial Insects: Aphids, lace bugs, and scale have many natural enemies. We can release these predators on your property in order to control the population of these aphids. This is a great option for homeowners that are worried about chemicals on their property or have kids that would love to be involved in releasing the bugs on the property.
Lace Bug Natural Enemies:
- jumping spiders
- assassin bugs
- lacewings larvae
- lady bugs
Scale Natural Enemies:
- lady beetles
- predatory mites
- small parasitic wasps
Aphid Natural Enemies:
- lacewing larvae
- lady bugs
Traditional Control: An arborist will be able to craft a treatment that will most likely involve horticultural oils or insecticides. These traditional treatments will kill aphids/scale/lace bugs on contact.
Beware Of DIY “Treatments”: Broad spectrum insecticides/oils that you find at home improvement stores or online actually kill the insects’ natural predators. Using this type of “treatment” is a temporary solution and the infestation will come back with a vengeance because there are no natural predators left to fight them off. Instead, trust a Certified Arborist to develop the correct treatment for your property that takes into account beneficial insects.

My pine tree appears to be leaking sap down the trunk
Some designers need etiquette and compassion lessons along with their color classes! I love your room, and I’m glad you painted the paneling! I agree that you need to pull some of the colors from your husband’s rug into the room. Choose a color from the pattern that you both love and draw it out into pillows, draperies, and art in the room. If budget is an issue, you could go to a local “ReStore” and see what they have to offer in a coordinating or complimentary colors. There is usually quite a bit of furniture, in good shape or that could use some TLC and the prices won’t break your budget. I would consider using fabric throws and pillows to bring color to the sofa (slip cover?). You might also consider an area rug on top of the oriental rug in a coordinating solid color to mitigate the darkness of the floor. It would probably open up your space if you moved the two chairs to the opposite side of the room, or replace them with a “Big” chair, which you could probably also find at ReStore. Leaving a walkway into the room from the doorway would open up the space and your wooden chairs could sit facing the sofa on either side of the fireplace. In case you aren’t aware of what a ReStore is…they are a donation point for Habitat For Humanity, with everything from flatware to building materials and everything in between. The things they sell are all in working order and in usable condition, most donated by folks who are remodeling or rebuilding their homes, and an awesome resource for good used items at cheap prices (for those on a slim budget). They are an awesome resource for DIYers and underutilized. I’ve found antique furniture there that only needed a good cleaning to bring them back to their original splendor, including fireplace tables (whose tops fold up to use as fire screens for a lady’s delicate skin) for $25, a high backed solid carved wood chair (c. 1890’s) with the original horsehair cushions in excellent condition, a sectional sofa in a beige leather (real leather not pleather) for $175 (retails today for $2300) that only needed a good cleaning and can be dyed to whatever color I choose. Since I’m a DIYer, I also found wooden slat doors that I’ve used to build closets, a jacuzzi bathtub in perfect condition with all hardware and plumbing for $150.00 (new sells for $2300.00), double bathroom sink with all hardware and plumbing parts and Real marble top for $50.00, solid wood entry door with 9 window lights for $50.00. The list goes on. Another way to bring color in is by using plants. Hang a basket on either side of your window (or use plant stands) with philodendrons growing. They grow very fast and would follow a line of white twine strung between the beams of the ceiling, creating a “garden feel” into the room (also good for cleaning the air in the room). They grow without much light, are very easy maintenance, and bring in a warmth that is surprising. You can insert pretty ‘fake’ blooms intertwined in the vines to liven them up if you like. Since your room seems to be somewhat dark, using sheers as window coverings would help to lighten the room. Consider lace drapes (can be created from lace tablecloths found at ReStore @$2 each with a single straight seam.) Lighting can be augmented with either up-lights or recessed lights easily installed with those open beams to bring light into the fireplace side of the room. Install and focus them on artwork or a large mirror over the fireplace to set a focal point and reflect light into the room (many types available cheap at ReStore). The new LED type lighting used under cabinets in kitchens can be used with some older fixtures and use very little power for a lot of return. Often these are available for $3-5.00 at ReStore with many different types of “shades” also available. I’m sorry if I sound like an ad for ReStore, but the organization helps many people who could not otherwise afford to purchase decent furniture and appliances, or retail building materials to furnish or rehab their homes. The proceeds from their sales go to building homes for people that are homeless or have such low incomes they cannot afford a home. They are also involved with programs for handicapped persons, including wounded veterans, in revamping their homes to meet their limitations. I hope some of my ideas will help to ignite your creative ideas and would love to see how you finish this beautiful room! Not an interior decorator, but loving all the ideas I find here!
Sap for a pine tree
Sap is a vital part of the tree’s life as it carries important nutrients and water through the tree. There are several reasons why sap oozes from trees.
If it is disease, fungus or pests, you can look for presence of sawdust, small holes in the bark, or sap leaking from a single place in the bark. Some pest infestations can cause the sap to look like popcorn, or a have a pinkish tint. Certain diseases can also cause white patches of dry resin.
You can also look for sap coming from pruning cuts, broken branches from storms and mechanical injuries.
As you noted, the release of tree sap can also be temperature related. In early spring, while many trees are still dormant, the fluctuation of temperatures may affect the flow of tree sap. Cold/warm weather cycles can produce pressure within the tree, forcing sap to flow out through openings.
Also, at the tip of pine boughs, there is a bud where pine cones develop in the spring. This bud is protected by a resinous sap. In drought years, there is less of this resinous sap. In wetter years, there may be some excess sap that can drip from these buds.
Finally, sometimes the dripping that we see is not actually sap, but rather ‘honeydew’. It is coming from aphid insects. They suck sap from the needles and excrete a liquid that is high in sugar and has a shiny appearance. Check the needles for small soft-bodied insects, and if found, a strong stream of water from a garden hose will dislodge them to reduce the level of feeding.
If none of these apply, you can take a sample to the Diagnostic Clinic at Arapahoe County Extension Office at 1690 W Littleton Blvd, Suite 300, Littleton, CO 80120; Phone: (303) 730-1920. There is a small diagnostic fee for in-county residents. Make sure the sample you bring is at least 18″ long and is indicative of what exactly you are seeing on the tree.
As far as removal of sap, you would need to do some internet research. A local auto body shop may be able to direct you to a product that can remove sap without damaging paint. You can also try to protect other items with a tarp or painter’s sheeting that can be disposed of.

This article is marked as a stub for the following reason:
- Needs mushroom tree production. Times need verification since 1.4.
The Tapper is a crafted item that can be placed on a tree to produce Maple Syrup, Oak Resin, or Pine Tar. It can also be placed on a Mushroom Tree to produce different mushrooms.
The Tapper can be removed from a tree by hitting it once with an axe or pickaxe. This leaves the Tapper intact and able to be reused.
If the Tapper is on a tree when it is struck by lightning, both the Tapper and its contents are destroyed.
Tappers placed on Maple Trees, Oak Trees, or Pine Trees continue to produce during Winter. Since Mushroom Trees turn to stumps in Winter, tappers placed on them produce nothing during that season.
- 1.4: Fixed issue that could leave trees unchoppable if tapper was removed in unusual fashion. Tappers can now be stacked in a player’s inventory and in chests.
