Yucca Plants – Care And Pruning: Tips For Pruning A Yucca
The yucca plant is a popular indoor and outdoor plant. One problem in caring for yucca plants that indoor owners have that outdoor owners generally do not is that indoor plants can grow too tall. They need to be trimmed back. Pruning a yucca may look harsh, but it is an excellent way to not only keep your yucca plant manageable but propagate the plant.
Yucca Plant Care and Pruning
With yucca plants, care and pruning are easy. When your yucca plant becomes too tall for the space it is in, gently remove it from the pot. Determine where the halfway mark is on the trunk or a point where you wish to be pruning a yucca that is above the halfway point. Using a saw or a sharp pair of loppers, cut the trunk in half.
Repot the bottom, rooted end of the trunk. Water well and then you are done with your pruning. While the plants are recovering, continue caring for the yucca plants as you normally would. In a short time, the plant will produce new leaves. It will recover to look as good as it did before, except that it will be much shorter and more appropriately sized.
Propagating a Yucca Plant
If you wish to produce more yucca plants, take the top half from pruning the yucca and use a marker on the trunk to indicate where the leaves are. After you have marked the trunk, cut off the leafy top. Plant the trunk in potting soil, making sure to have the end that previously had the leaves pointing up. Check the mark on the trunk if you have forgotten which end is which.
In a few weeks, the trunk will have rooted itself and a few weeks following this, the trunk will start producing new leaves. Continue caring for the yucca plants as they grow.
Best Time for Pruning a Yucca
Like most plants, the best time for pruning a yucca is right before it goes into its growth period. This will be in early spring. While early spring is the ideal time, a yucca can be pruned anytime. Just make sure the yucca plant gets plenty of light while it is recovering.
Pruning Yucca Flower Stalks
Though not exactly pruning, many people wonder about cutting off the yucca’s flower stalk after the blooms have faded. The flower stalk can be pruned off at any time, even before it is done blooming. Simply cut the stalk off with a sharp pair of pruning shears or cutter at about 3 to 4 inches above where the stalk emerges from the main stem.
Like all things about yucca plants, care and pruning is very easy. It may seem drastic, but I assure you that your yucca plant considers this to be a very normal thing.
Yucca plants take time to grow, but worth it
Part of the joy of gardening involves trying out new plants and being rewarded with a successful venture. Some of these rewards come within the first growing season and others take many years to display their fine qualities. Many, that take patience, usually put on a show that can be quite stunning.
Six years ago, I planted a seedling yucca plant that was about three inches tall. It sort of resembled a wide-leafed grass appearing from the garden floor. In the first year it grew to about 5 inches tall and equally as wide. With images of grandeur dancing in my head, I thought within a couple of years I would be rewarded with a beautiful flower spike. Much to my dismay, this did not come quickly.
listen live watch live
In the fourth growing season, it was nearly 18 inches tall and wide. After the winter had passed, I thought I had lost it this time around due to root rot from the cool wet spring, but soon it decided to come through and grow. Still there was no flower spike for the season. During its fifth year, it came through the long, hard winter well, but still it did not send up a flower spike. If it hadn’t turned out to be such a healthy plant, I would have been ultimately discouraged.
This year was its sixth growing season and I watched it closely. While I noticed other yucca species in town develop their flower spikes and begin to bloom, mine only created leaves. Feeling another season of defeat underway for this flowerless plant, I accepted the fact and continued working in the garden with some of the other blooming plants that needed my attention.
In mid-June, I was working on a new project and happened to look at this yucca plant in the background. All of a sudden, I noticed a change and nearly dropped to the ground in amazement. The yucca plant of six years was finally sending up its first flower spike I had been waiting so long to appear. Right at the tips of the leaves was a central shoot that resembled a thick spear of asparagus coming up about the thickness of a thumb. The time had arrived that I was finally going to see this plant bloom for the very first time.
As the weeks passed, the elongating stem began developing short little branches covered in small buds. Eventually there were as many as 100 new buds on the stem that had reached nearly five feet tall. Within the first week of July, the creamy white bell-shaped flowers began to open from the central region. Each flower had six delicate lance-shaped petals emitting the scent of fresh smelling bath soaps. As more flowers began blooming, it became a glowing candelabra of hanging bells that scented the humid evening air.
After six years of waiting, my yucca plant had finally rewarded me with the display of flowers that was well worth the wait.
Yucca plants enjoy a hot and dry location with a sandy soil. Mostly native to the Southwest and Central American regions, some will grow as far north as the Dakotas. Most yucca plants in the state of North Dakota are known as Soapweed Yucca or yucca glauca. Its leaf rosettes create leaves about 18 inches long, which are rigid and sharp to the touch. You don’t want to fall into one of these plants or trip over one at night as you may poke your eye out! Most are common to the Badlands of North and South Dakota and some are planted in residential landscapes.
Another common yucca of the Southwest is known as the Joshua Tree or yucca brevifolia. These get quite large and are a protected species. This selection usually grows actual trunks and stems with numerous floral spikes.
The yucca filimentosa is most commonly grown in the coastal sands regions, but is also hardy in our area as long as it is not in a wet, heavy soil.
The yucca plants of the prairies where commonly referred to as the Ghosts of the Graveyards as they were commonly seen growing in the graveyards of the West. At night, their stems of flowers seemed to glow above the foliage like a floating apparition.
Yuccas always get noticed in the landscapes while in bloom, as they are not a common landscape plant. As with many plants in the garden that get noticed, it is the unusual and spectacular that receive the most attention.
This week is the annual AAUW Garden Tour. It will be from 5 to 8 p.m. Wednesday. This tour will feature four unique and interesting gardens in the area along with mine. This is the perfect opportunity to get outside on a beautiful summer evening to view some new and exciting ideas. Even if you are not looking for a new project, it will fill your evening with the peace and relaxation that only a garden tour can offer.
Invite a friend along and share a conversation or the perfect photo moment in a unique garden setting. It is a good time to share ideas with the featured gardeners and find out what techniques works for some and which ones work for others. Even as the garden editor, these tours teach me new concepts in design and plant layout. Each and every gardener has success and failure stories to share. Without these stories, we would all be on our own in our journey through gardening. We learn from each other so we can grow more within ourselves and develop our ideas to a new level.
You can purchase your tickets at Don’s House of Flowers, Country Gardens, The Arts Center, Don’s Garden Shop on Business Loop East, The Buffalo Mall, Lloyds Toyota and The Garden Gate. Advanced tickets will be $8 each and $10 the day of the tour. Grab a friend and have an evening of fun and enjoyment and bring lots of questions to ask the various gardeners on the tour as they would be more than happy to share some stories of their own. Have fun and we will see you there!
Everything You Need to Know About Your Yucca Plant
Weeding out weaker plants with unrelenting heat and unfamiliar fauna, only the strongest emerge from the desert, and the resilient yucca plant is proof. Native to the deserts of the southwestern United States and Central America (though they’ve been known to range as far as Canada and parts of the Caribbean) yucca plants prosper in arid and moistureless climates. This resilience doesn’t just make them a great fit for harsh landscapes—it also makes them great houseplants.
“Yucca is actually a genus plant that, believe it or not, is part of the asparagus family,” says Jesse Waldman of Portland-based plant shop, Pistils Nursery. “Not all yucca plants will thrive indoors. Two species that do particularly well, though, are Yucca Guatemalensis and Yucca Elephantipes, which are both more commonly known as yucca cane (or just yucca).”
Loved for their dagger-like leaves and sturdy trunks, yucca plants come off as decidedly quirky when compared to more popular houseplants like fiddle-leaf figs or monsteras. To get the lowdown on these low-maintenance plants, we asked Waldman and Little Leaf expert Kevin Martinson for their fail-proof tips for caring for the desert green.
The General Gist
There are 49 species and 24 sub-species of yucca, which means you’ve probably seen it 100 times before and never knew it. Thanks to their desert roots, yuccas love direct sunlight and can survive without water for long periods of time. In other words, this is a plant you won’t feel guilty about leaving at home when you leave for a two-week vacation.
“Yucca canes prefer to be slightly root-bound in coarse, well-draining soil that’s dense enough to stabilize the heavy trunk,” shares Martinson. “Because they’re extremely drought-tolerant plants, the quickest way to kill a yucca is by overwatering.”
While we’re particularly interested in caring for yucca indoors, these spiky plants most commonly thrive out in nature. And when we say thrive, we mean thrive. “In the wild, these growers can reach 30 feet or higher,” says Martinson.
When grown indoors, yucca plants can soar up to seven feet tall. Since the foliage typically sticks to the top of the trunk, it’ll feel like having a palm tree in your home. “Though the growth habit and height depends on the exact species you have, will ultimately grow tall, woody trunks, which can eventually reach up to the ceiling (though this would take quite a while),” says Waldman.
Let there be light! Like most desert plants, yuccas love basking in sunlight—and lots of it. Martinson notes that although yuccas can tolerate lower levels of light, they often prefer sunny south-, west-, or east-facing windows where they can catch direct or indirect sunlight. If you notice white or brown splotches beginning to form on the leaves, you’ve been warned that your yucca is getting too much light.
“Direct sun magnified through windows can burn the plant. Be sure to adjust your care regimen accordingly. Less light means the plant will need less water to thrive and will also grow a bit more slowly,” suggests Waldman.
As a general rule for all houseplants, Waldman notes that it’s best to adopt a “less is more” watering approach. The simplest way to know if your green friend is ready for a drink? Stick a finger down into the soil. If the first few inches are totally dry, they’re thirsty. You’ll know you’ve quenched their thirst when you see water coming out of the drainage hole at the base of the pot.
“Plants can typically recover much more readily from the stress of underwatering (drought) than overwatering (root rot),” says Waldman.
When it comes to yucca specifically, you’ll likely end up watering your plant once every two weeks. Though, this will really depend on how much light your plant is getting. “During winter months, watering frequency can be cut in half since the days are shorter and the plant will be receiving less sunlight,” explains Martinson.
Because yucca tends to grow in nature in nutrient-deficient soil, fertilization isn’t usually necessary. However, if you do choose to fertilize, Martinson suggests using a nitrogen-based fertilizer once or twice a year during the growing season (mid-spring). Another option is re-potting regularly. “The fresh soil will provide a nutrient boost to your plant,” adds Waldman.
Tip: “If the plant is too large to re-pot, remove the top two to three inches of the old soil and replace it with a fresh layer,” shares Martinson. The first time you pot your plant, pick a pot that is two to three inches larger in diameter than the plastic grower’s pot that it comes in.
If the lower leaves of your yucca plant are damaged or unsightly (leaves naturally die and turn yellow as the plant grows taller), pruning is a great way to keep your yucca looking fresh. Generally, this can be done by gently pulling off or cutting the base leaves.
“If your yucca blooms (though it’s not super frequent indoors), you’ll want to cut off the flower spike after the blooms have expired. You’ll cut it a few inches from the base of the flower spike,” explains Waldman.
If it’s the height of your yucca that you’re interested in changing, you’ll have to be a touch more careful about the process. “If your yucca is growing too large for your indoor space, you can cut the trunk in half using a handsaw,” explains Martinson. “Re-pot the rooted portion, and then water thoroughly. Continue to care for it as you previously were and eventually new leaves will sprout.”
All in all, yucca is incredibly easy to care for. The only thing to watch out for? Root rot—the telltale sign you’re overwatering. “Root rot is a common issue for yucca cane plants if they’re not receiving adequate light or are in poorly draining soil,” says Martinson.
You also shouldn’t leave your yucca in a dreary, dark corner. “Too little light will also weaken the plant, resulting in poor growth and making them more susceptible to pests,” adds Waldman.
Keep an eye out for bumps, discoloration, webbing, and sticky residue, all of which can indicate you’ve got unwanted creepy crawlers hanging around. “Scale is the most common bug that you might find on your yucca. Be sure to take care of this problem early, as once it’s infested, scale can be difficult to treat,” says Waldman.

Topic: Pruning, Seasonal Tasks
Title: Winter pruning for yucca in Michigan
Answered by: Barbara Medford
I live in SE Michigan and have an outdoor yucca plant that has grown quite large. My father tells me that I can literally cut it down to the ground in the fall and that it will grow back the following season. I have small kids and little time to garden and prune. So to me, this idea of just cutting it down to the ground vs. pruning is appealing. Please tell me if I will kill the plant by doing this.
The only yucca that has naturalized into areas as far north as Michigan is Yucca filamentosa (Adam’s needle). It is actually a native of the southeast and eastern parts of the U.S., but has moved into Michigan. Living as we do in near-desert Central Texas, with yuccas all around, we still find it hard to believe that there is a yucca that perseveres in snow and cold. Yucca does not ordinarily need any pruning, except perhaps to take out any dead or broken blades. You need to have this plant where you want it to be, because trying to dig out the root will (a) not work, they are HUGE and (b) cause a whole lot of new little plants (commonly called “pups”) to begin to grow around the area. The same thing will happen if you cut the plant off at the base-it will just guarantee its survival by sending out more little plants. And cutting it off at the base would be a real challenge, requiring something along the lines of a chainsaw and a suit of armor. The only pruning that is needed is of the bloom stalk, which should be cut down as close to the bottom as possible, in order to keep the plant tidy, as soon as it finishes blooming in late summer.
Unless you have a whole lot of room to be filled up in your garden, don’t try to cut off or dig up anything on your yucca except the bloom stalk. When you were told that the yucca would come back if you cut it off at the base, you probably didn’t realize that several would come back at the cut-off base, and then, next year, when you cut those off at the base… and so on and so on. How do you feel about a yucca forest in your garden?

Caring for Your Yucca Plant
The Yucca plant, when kept as a houseplant, needs to be watered moderately during its growth period in spring and summer and sparingly during its resting period in fall and winter. As a general guide, an established Yucca plant will probably only need to be watered around once a week during growth, cutting back to once every two or three weeks for the remainder of the year. This will vary depending on numerous factors, such as how big your plant is, how much light it gets, and what temperature your plant is living in. Because of this, you need to pay attention to your specific plant, taking note of its condition to let you know how often it likes to be watered.
The best watering method for this plant is to allow the plant’s soil to dry out between each watering. Check the soil by dipping a finger into it, noticing if the top few inches are dry or moist. Only proceed with watering if the soil is dry to the touch; otherwise, wait a few days and test again. If you’re unsure, always err on the side of caution with the Yucca plant. It is fairly drought-resistant, so it will be much safer to neglect its watering needs a little rather than overwater it and cause irreparable damage.
The Yucca plant is especially susceptible to root rot, which is the result of too much water. To ensure your watering technique is appropriate for your plant, always follow the dip test guide and check the soil for moisture. When you do water your Yucca, water it liberally until water runs out of the drainage holes. Be sure to remove the drip tray shortly afterward and empty it because the Yucca plant should never be left in standing water.
Drainage is particularly important for the Yucca plant as it responds very badly to being waterlogged. Ensure your plant is growing in well-draining soil and that your pot has drainage holes so that excess water can escape (Better Homes and Gardens). This plant is not sensitive when it comes to soil type, so any well-draining soil mix will be fine. You don’t need to overspend unnecessarily on soil for the Yucca plant as it will be perfectly happy in low-quality soil, as long as it’s other needs are being met.
Yucca plants that are growing directly in the ground outside will have much lower watering requirements than Yuccas kept as houseplants. They are fairly drought-tolerant, so you should be able to get away without watering at all throughout fall and winter and with just an occasional watering during spring and summer. Depending on how frequently rain falls in your region, you may never need to water your outdoor Yucca plant at all.
The Yucca plant is native to very hot regions of South America and the Caribbean, so it does well in high temperatures. It also tolerates low temperatures very well as it is adapted to desert conditions, which can drop to lows of 30° F overnight. The Yuccas ability to handle such a wide range of temperatures, from 30° F to 90° F, making it the ideal houseplant or garden plant for almost any part of the world. It’s very unusual for tropical plants to handle temperature changes with such ease, so you can make the most of this by placing your Yucca in an area that most plants would not be able to tolerate, such as an entryway where drafts are commonplace. The only caveat to this is that once a Yucca has acclimated itself to indoor conditions, it won’t tolerate being taken outside in cold temperatures.
It is not uncommon for people to move their Yucca houseplants outside during warmer months to allow them more natural light to thrive and grow. If you do this, you must remember to bring the Yucca back inside before the first frost arrives, as this could be very damaging to a Yucca that is accustomed to living indoors. For Yuccas that are kept as houseplants, ideal temperatures are those that you ordinarily find in a home. If you are comfortable with the temperature in your home, then your Yucca will be too. Ideally, don’t allow temperatures to drop too far below 50° F.
The Yucca plant adores sunshine and will thrive in bright, direct light. It is quite unusual for a houseplant to tolerate direct light so well, making it the ideal plant to put in a sunny window where most plants would scorch. The Yucca will also fare well in bright but indirect light and artificial light. Being a particularly easygoing plant, the Yucca can tolerate low light conditions, but its growth will slow down significantly, and its flower production may cease altogether.
Outside, a Yucca plant can be situated in an area that receives full sun or partial sun, allowing it to receive at least a few hours direct sun each day. This will result in a happy and healthy lush looking plant.
Moderate humidity is ideal for this plant, so average humidity found in homes will be perfectly suitable. Even if you have exceptionally dry air in your home, the Yucca should fare just fine. Misting with water isn’t necessary to increase humidity, as this plant easily adapts to most conditions.
Your Yucca houseplant will benefit from a monthly fertilizer feeding during spring and summer, though this should be stopped completely for the remainder of the year. Use a liquid fertilizer at half of the recommended strength. Outdoor Yucca plants can be fed once a year during growing season. Typically, any fertilizer formulated for outside use will be just fine, though a slow release fertilizer would be preferential.
As a slow-growing plant, the Yucca usually only needs to be repotted every two years. It responds well to a tight-fitting pot but shouldn’t be left root-bound for too long; otherwise. its growth will be stunted. Repotting your Yucca is most beneficial for the plant’s physical support. As it grows, the plant will become top-heavy, so a larger pot is needed to give the plant some stability and prevent it from falling over. Select a pot one size bigger than the Yucca’s current pot, and, ideally, move it into the new pot in the spring.
Mature Yuccas can be difficult to repot due to their size. As long as the pot is already a suitable size to support the plant, you can forego repotting it and simply refresh the soil by scooping out the top layer and adding new soil in its place. When handling the plant for repotting, always wear protective gloves and ensure your arms are clothed to prevent cuts from the Yucca’s sharp leaves. The tips of many Yucca varieties are needle sharp and have actually caused numerous injuries to inner ears when people inadvertently were poked in the ear by the plant. In an Australian study, injuries ranged from mild to severe, with some cases of permanent hearing loss (ABC Radio Melbourne).
The Yucca plant grows very slowly and should rarely, if ever, need pruning. Although they grow at a minimal speed, they do grow to be very big, both in height and in spread, so you need to be prepared for this when growing a Yucca indoors. If you want to prevent your plant from becoming too big, then you can reduce the frequency that you repot it, leaving three or four years between each repotting.
If your Yucca has already become taller than you would like it to be, the only option is to chop off some of the height. To do this, you will need to saw through a main stem, reducing it to a size you are happy with. You will be left with a slightly unattractive-looking stump, but new shoots should sprout from this over time. If you do decide to hack off the top section of your Yucca, then do so with caution. In some instances, cutting back a Yucca is a trauma that the plant cannot recover from. The new stump may not undergo new growth, and the remainder of the plant may die off. If you proceed with cutting back your Yucca, do so in the knowledge that there is a chance that you may lose your plant (Royal Horticultural Society).
Propagating a Yucca can be done in various different ways, though the most successful way to propagate the plant is from offsets or stem cuttings.
To propagate using offsets, you need to locate an offset on a mature Yucca plant and slice it off. Offsets are produced on older Yuccas, and grow off the stem underground. The best time to slice off an offset is in the spring when you are repotting the plant. Some offsets may already have formed their own roots while still attached to the mother plant; these can be cut away from the mother plant and placed directly into a pot of soil where they will develop into a new Yucca.
Offsets that do not have their own roots already will need to be treated differently and will take a little longer to grow into a new plant. Put the cut offsets into a cool and dark area for a few days to dry out, and then, move them to a pot of ground pumice. Place the pot in a cool but bright area and wait for roots to develop. After around two weeks, roots will form, and at this point, you can begin to water the offsets every week or two.
Roots will be established within one to three months, at which point, they can be potted into individual pots. Water sparingly only when the top layer of soil is dry and do not feed until the plant has fully developed. Keep the new plants in bright but indirect light, moving into full sun locations when they are more established.
Using stem cuttings is the other most common propagation method for Yuccas, and it is ideal if you want to cut back your Yuccas height anyway. Using a stem cutting of at least four inches in length, dip the raw end into rooting hormone and then, pot it into soil. Ensure the stem is sufficiently supported by the soil so that it doesn’t topple over. Keep the soil moist but not wet and wait for new growth to happen. When new shoots appear out of the top of the stem, it means roots will also be sprouting from the bottom of the stem. Once the cutting has developed into a plant in its own right, you can continue with usual Yucca care.
There are 40 species of Yucca, with half of these being native to the United States. They vary in size from miniature plants to giant towering ones, and some have unusual features such as edible flowers or medicinal roots. Some of the most popular varieties of the Yucca plant are listed below.
Adam’s Needle- Yucca filamentosa
As suggested by its name, this Yucca has very sharp leaves that can easily cut skin if you brush past it with bare arms or legs. For this reason, plant it in secluded corners of gardens where pets and children are unlikely to roam. The special feature of this plant is the vertical flower stalk, which reaches up to eight feet upwards. The stalk is adorned with large white flowers shaped like bells, which give off a sweet smelling fragrance and attract hummingbirds.
Spanish Bayonet- Yucca aloifolia
This enormous Yucca is native to the southeastern US and grows to heights of eight feet tall. As you would guess from its name, it is an especially cruel variety, easily injuring passersby with its razor-sharp, sword-shaped foliage. For this reason, handle it with care while wearing protective clothing, and when planting outside, make sure it’s away from walkways or areas with heavy footfall. In the summer, this plant produces an abundance of flower clusters up to two feet in length.
Spineless Yucca- Yucca elephantipes/ Yucca guatemalensis
This is the most common variety of Yucca used as a houseplant. Outside, it can reach heights of 30 feet, though it is a very slow grower and will happily live inside for many years before it outgrows the space. This variety of Yucca doesn’t tolerate the cold well, which makes it ideally suited to life indoors. Another reason it a popular choice of houseplant is the fact that it’s leaf tips are not needle-sharp like most Yucca plants, hence its common name of Spineless Yucca.
Banana Yucca- Yucca baccata

As the name implies, this plant grows edible fruits of a similar shape to a banana. They should be cooked before consuming and taste quite pleasant. At around five feet in height, this is one of the smaller Yuccas. In the summer, it features flowers that can range in color from white to purple. The foliage has a slight blue hue, which gives the plant added appeal.
Pale Yucca- Yucca pallida
This Yucca is native to Texas and is versatile as a garden plant as it thrives in both shade and full sun. Its pale green leaves have a blue tint to them, and the flowers are white. This plant is ideally suited to use as ground cover, as it only reaches around one foot in height, but it has good leaf spread.
This variety of Yucca has medicinal qualities. It is a rich source of saponins, which are claimed to relieve symptoms of arthritis and joint pain. Extracts of this Yucca are often found in pet food and other animal food to help support good joint health.
Thompson’s Yucca- Yucca thompsoniana

This cold-hardy variety of Yucca grows to heights of 10 feet. Its leaves are particularly striking in shades of blue and gray. Thanks to its tolerance of low temperatures, it is grown outside as far north as New York.
Twisted Leaf Yucca- Yucca rupicola
This Yucca has green leaves with red edging which are several inches wide. Curly fibers sprout alongside the leaves in shades of white, giving an interesting juxtaposition of both dainty and sturdy foliage. As the plant grows taller, to several feet in height, the leaves twist around to give it its common name. Native to Texas, this variety thrives in a range of lighting conditions, from full sun to partial shade.
