Coniferous trees and deciduous trees

What “Pine” Trees Lose Their Needles in Winter?

Across the world, there are more than 100 species of needle-bearing trees. Some sport long, smooth needles while others are short and prickly. Some radiate their emerald green while others flaunt a more mellow blue.

It doesn’t stop at looks–some of those trees even grow differently. In true evergreen form, most hold onto their needles all year, while others completely shed their needles in winter.

If your needle-bearing trees lose all their needles in winter, they aren’t in danger. They’re just like the other trees we watch transition in fall. Learn which trees drop their needles, and find a new, true evergreen if you need one!

Which “Pine” Trees Lose Their Needles in Winter (And Evergreen Trees That Don’t Drop Needles)

All trees with needles will eventually shed some needles. As the trees age, older needles on the inside of the tree brown and drop off to make room for new needles. This happens to a portion of the tree’s needles every year.

But there is a small group of needle-bearing trees, called deciduous conifers, that drop all their needles every year. So if you think you have a pine tree, but it drops all its needles every winter. It’s actually one of the below trees!

What conifer trees lose their needles in winter?

There are about 20 deciduous conifers, which make them quite rare!

Here are the most popular ones:

  • Larch trees, including European larch, tamarack larch and western larch

  • Baldcypress trees

  • Dawn redwood trees

When do deciduous conifer needles stop falling?

Just like our favorite maples or oaks, conifers that lose all their needles start by changing to golden and bronze shades in the fall. Then, they begin shedding needles in fall and are bare by winter.

What pine trees don’t shed needles?

True pines won’t get rid of their needles because they’re evergreen!

  • White pine tree

  • Jack pine tree

  • Sugar pine tree

  • Red pine tree

  • Pitch pine tree

  • Swiss Stone pine tree

  • Loblolly pine tree

  • Short and longleaf pine tree

Remember–pines that hang onto their needles can still brown from time to time. When that happens, it may be a sign your tree needs your help!

My Pine Tree is Losing its Needles

Have many of the needles on your pine tree have been dropping off lately?

Don’t worry and don’t cut the tree down! There is a perfectly natural explanation.

Though pines and most other conifers are called evergreens, their needles do not stay alive and green forever. Generally, new needles are produced every spring and summer and last for two to four or more years. So, as the tree grows larger year-by-year, newer needles are always at branch ends and older needles are farther back in the crown.

As needles age, they become less efficient at producing food for the tree. They also become more shaded by newer needles. For these reasons, old needles finally turn brown and drop off. This doesn’t hurt the tree because several year’s worth of newer needles are always there to replace the old ones.

Do be concerned, however, if your tree is losing needles at the branch tips. These needles are young and have not out-lived their usefulness. The culprit is probably some type of disease or insect.

So, if one-third to one-fourth of the needles on the inner parts of your evergreen tree are falling off, it is probably just a normal sign of aging. Just rake up the dead needles, or better yet, leave them under the tree for a good mulch.

For all the benefits pine trees can offer, they also suffer from their share of problems.

One of the most common and most vexing is when your pine tree starts losing its needles.

When this happens, it can spell the death of the tree.

Unlike the leaves on deciduous trees, pine trees never regrow their needles. If the tree loses too many, it won’t be able to survive.

Therefore, it’s important to spot and treat problems before they prove fatal to your tree.

Here are some of the common reasons that pines lose their needles, and what you can do to prevent them, or reverse their effects.

Needle Blight

What is it? Dothistroma needle blight and diplodia tip blight (also known as Sphaeropsis blight) are caused by certain fungi.

When infected, the tree will show less vigorous needle development and yellowing or browning of newer needles.

When it gets into a wound on the trunk, it can also cause girdling.

The fungi that cause these diseases prefers wet, cool springtime conditions and takes advantage of injured trees.

What to do: Restrict pruning to the winter when the fungus isn’t present.

Regular and thorough watering will help the tree be more resistant to problems.

If infection should occur, using a strong fungicide is recommended.

Pine Wilt

What is it? This fatal condition is caused by a certain roundworm species called the pine wilt nematode.

This tiny, destructive worm eats the pine tree’s cells, causing it to wilt from an inability to transport water and nutrients.

However, this nematode isn’t like the others.

Unlike most of its soil-dwelling brethren, the pine wilt nematode infects the upper parts of the tree.

What to do: Once a tree is infected with these pests, they can be spread to nearby healthy trees.

Any tree with pine wilt should be removed and burned.

If you really want to save the tree, nematicides are available, but they are expensive.

Pine Bark Beetle

What is it? These insects tend to infest ailing pine trees and aren’t picky about which pine species they exploit.

These destructive pests burrow into the bark, hindering the tree’s ability to transport nourishment and water.

There are multiple species of pine bark beetle, but they all affect pines the same way.

What to do: Check the bark for squiggly lines, check the needles for browning, shedding and inspect the branches for signs of death.

Keeping pines watered and fed properly will help them resist infection and degradation.

Infected pines should be removed and burned to prevent additional infestations.

Phytophthora Root Rot

What is it? This soil-borne fungus tends to infect pine trees, harming or killing them in the process.

Although this fungus lives in the soil, the symptoms are presented on the above-ground portions.

Signs of an infection include reduced growth, reddening or browning needles, dying branches, falling needles and eventually, death.

What to do: The fungus is common in soil with poor drainage, wet soil and warm temperatures.

It can be prevented by planting your trees in well-drained locations.

Professional soil tests from your local tree care company or university agricultural extension can tell you if this fungus is present in your soil.

If infection occurs, commercial fungicides are often helpful.

Tamarack: A different kind of pine tree

Have you ever driven around the Poconos in late autumn and early winter and noticed evergreens that appear to be dead or dying? I’m not referring to the normal autumn shedding of some needles, but rather to trees covered with gold to rust-colored needles, or nearly bare, with only the skeleton of trunk and branches remaining.

I’m not referring to the normal autumn shedding of some needles, but rather to trees covered with gold to rust-colored needles, or nearly bare, with only the skeleton of trunk and branches remaining.
Have you ever wondered what could be causing the trees to die? Or wondered why they hadn’t been removed? Surely, these are trees only Charlie Brown could appreciate.
The next time you spot such a tree, take notice of its immediate environment. If the area is wet or boggy, it might be a clue that you are looking at the deciduous tamarack.
Tamarack (Larix laricina), also known as American larch, is a very unique member of the pine family — one that loses its needles in fall. Only one other conifer shares this deciduous nature — the bald cypress.
Tamarack is native to Pennsylvania and can be found in much of the Northeastern United States and Canada. Habitats where tamaracks thrive include boreal forests, bogs and muskegs. This native tree is ideally suited to wet, poorly drained sphagnum bogs, withstands high soil moisture and high acidity, and is cold-hardy. Introduced varieties, such as European larch (L. decidua) and Japanese larch (L. leptolepis or L. kaempferi), can also be found in the Pennsylvania landscape.
Tamarack has a narrow trunk that is covered with thin, gray bark on younger trees and red-brown, scaly bark on older trees. The tree reaches heights of 50 to 75 feet, is conical-shaped, and has a somewhat open and sparse growth habit.
Small, egg-shaped cones (about ¾ inches long) are prevalent on the tamarack; the older trees (50 to 150 years old) are the most prolific cone-bearers. Seeds are contained in the cones, but in the wild, germination rates are low. This is often due to the consumption of seeds by rodents, or to bacteria and fungus that render the seed less viable. In addition to being eaten by mice, shrews and voles the seeds are also a favorite of crossbills. Birds may use the tamarack for both nesting and as a food source.
Without question, it is the needlelike leaves that draw most of the attention, and that demonstrate the unique deciduous nature of this conifer.
In spring, the needles appear in soft blue-green tufts or clusters that deepen in color during the summer. In autumn, the needles turn a striking yellow-gold before being shed.
And just because the tamarack loses its leaves in autumn does not mean that this tree lacks four-season appeal. In winter, the stark structure of the tamarack, especially when the branches and cones are dusted with snow, can provide unexpected beauty.
If your landscape provides the challenge of a wet or boggy area, you just might find a solution in the native tamarack. If you are not fortunate enough to have such a unique environment, and the American larch is not adaptable to your landscape needs, you might consider one of the other varieties of tamarack. Cultivated dwarf or weeping varieties are also available, and are more suitable for container plantings or inclusion in smaller yards.
Whichever the choice, once you have witnessed the tamarack in all seasons, you are bound to agree that this is surely no Charlie Brown Christmas tree.

My Evergreen Is Losing Its Needles! Is That Normal?

As fall approaches, we’re used to seeing trees like maples and oaks change color and the leaves falling to the ground, blanketing your yard. But what if you notice evergreen needles (from trees like pine, spruce, fir, yew or arborvitae) on the ground as well? What do yellowing and dropping needles mean for your conifers?

Don’t panic. Most conifers do lose needles in the fall, just like deciduous trees lose their leaves. Although these trees are usually referred to as “evergreen” trees, that doesn’t mean all needles on the tree stay perpetually green. Some will yellow, die, and fall off the tree.

However, unlike deciduous trees that lose all of their leaves at once, healthy evergreens always have some needles on the tree, retaining their overall green appearance even throughout winter.

How can I tell if it’s normal autumn needle drop or something worse?

While some fall needle loss is normal, there are instances where needle loss can signal a pest issue or disease that needs professional attention.

First, check which needles are turning yellow and being dropped. If they are the older needles on the inside parts of your conifer tree, and the yellowing is spread evenly from top to bottom, then the tree is fine. It’s normal for your tree to lose some of the previous years’ needles during the fall months.

However, if the newer needles at the tips of the branches are turning brown and dropping, or if needle loss is happening at other times of year, then your tree might need to be inspected by an arborist to determine what’s wrong.

The other thing to look for is whether your tree still appears green from a distance. If it does, that’s a good sign. But if you notice patches that are brown or orange or that are missing needles, that may be a cause for concern.

White pines can turn dramatically yellow in fall. Even this much yellowing is normal.

Does weather affect needle loss in conifers?

Drought and heat stress can affect your conifer’s needles, turning them brown and making them drop prematurely. These conditions can also make fall needle drop more obvious; trees under stress will drop more needles.

Make sure that your tree is getting enough water if there has been a drought or prolonged period of hot weather.

Is fall needle drop worse in some kinds of trees?

The fall loss of needles is usually more obvious on mature white pines than on other conifers. Often, the whole tree can look yellow. White pines only retain the current year’s needles while shedding the previous two years of growth (so there are more yellow than green needles on the tree). It may look alarming but it’s perfectly normal.

Do all conifers lose needles in fall?

All of the above information is applicable to conifers such as pine, spruce, and fir. There are a few types of conifers, however, that lose all of their needles each fall.

Conifers get their name because they have cones (for instance, a pinecone on a pine tree). Not all conifers are evergreen, however. Some are deciduous, which means that they lose their needles in the fall, just like maple and oak trees lose their leaves.

Dawn Redwood

Native to China, Metasequoia glyptostroboides, or Dawn Redwood tree, grows quite well here in eastern Pennsylvania or New Jersey (it’s hardy up to zone 5). It grows quickly, reaching heights of up to 90 feet. If you want to see some in person, you can visit three in Central Park in New York City, in a section called Strawberry Fields that was dedicated to John Lennon. The three dawn redwood trees symbolize eternal renewal because of their needle drop – they lose their needles each fall and then regrow them each spring.

Dawn redwood needles stay green throughout the growing season but drop in fall

Larch (also called tamarack)

European larch is commonly planted in the northeastern United States, and its needles turn a bright yellow before dropping every year.

American larch, also called tamarack, is another variety, and has the same bright yellow needle drop every fall. Tamarack does not do well in shade, and its thin bark makes it highly flammable.

Bald Cypress

Native to the southeastern USA and typically found in swampy areas, bald cypress (Taxodium distichum) is remarkably hardy (up to zone 4) and tolerant of a range of soil conditions (including dry conditions).

They also drop their needles (usually in winter) and grow them again in spring.

The Bottom Line on Conifer Needle Loss

Overall, yellowing or browning and dropping needles in the fall is a normal part of a conifer’s growth cycle. Enjoy them as part of the changing of the seasons.

Be sure to note, though, if large sections of needles are changing color or dropping during other parts of the year.

You can always contact Organic Plant Care in Flemington, NJ to schedule a tree consultation. Our ISA Certified Arborists can determine if your conifers are healthy and come up with a plan to keep them that way.

Seasonal needle drop


Every year, evergreens experience a seasonal needle drop that is a normal part of the plant’s cycle. Needles of conifers have varying life spans and do not remain attached indefinitely to the tree. Many evergreen needles, as they age, will turn yellow, then brown, and drop off after one to several years. The change can be gradual, or, with some species, quite rapid. Seasonal needle drop can cause concern to homeowners who are not familiar with this natural occurrence. In times of drought, needle browning may be particularly noticeable, because more needles are shed in response to environmental stress. White pines show the most dramatic needle drop change.
Their annual loss of needles can be especially alarming on mature white pines, as the number of yellow needles outnumbers the current season’s green growth. Typically, white pines will retain needles for three years, but in autumn, 2-or-3-year-old needles will change color and drop, leaving only the current season’s growth still attached. Austrian and Scots pines usually retain their needles for three years. Red pine drops its needles in the fourth year. Spruce and fir needles also turn yellow and drop, but the change is usually less noticeable because their older needles are thinned progressively, making the process more gradual than in pines.

Arborvitae sheds branchlets rather than needles which usually turn brown as they age, yet remain on the tree for quite some time before falling. Yew needles turn yellow and drop in late spring or early summer of their third year. Check your plants regularly. If the current season’s growth is discolored or wilted, the tree may be suffering from a more serious disease or insect problem and should be diagnosed to determine if control is warranted.


There is no control required. As long as needle drop is restricted to older growth and is not excessive, the “problem” is simply seasonal needle drop, a normal and natural process. Always follow good cultural practices to keep trees healthy.
