Yuccas are popular accent plants that contribute a desert-like or tropical look to gardens and landscapes. Unlike some yucca species, curved leaf yucca can grow in relatively cool and wet regions. A curved leaf yucca growing in a courtyard or a rock garden adds a decorative touch.

What is Curved Leaf Yucca?

Curved leaf yucca (Yucca recurvifolia, also known as Yucca gloriosa var. recurvifolia) is popular in ornamental gardens, and it has the advantage of having leaf tips that are less sharp than in other yucca species.

Yuccas are related to agaves and, like them, are native to the Americas. This species is native to the Southeastern United States. However, it can grow across the U.S. in zones 7 to 11, from Arizona to the Pacific Northwest, and also in similar climates worldwide.

Curved leaf yucca plants have long, narrow leaves that are bendable and curve downward toward the tips, giving the plant its name. The blue-green leaves are 1.5 to 3 feet (0.4 to 0.9 meters) long. Varieties with variegated and other unusually colored leaves are available. Each plant usually produces one semi-woody stem but may produce branches.

Curved leaf yucca flowers appear in late spring or early summer, and in some areas, the plant can bloom again in fall. The white, bell-shaped flowers are borne on a large, showy flower cluster up to 5 feet (1.5 meters) tall.

How to Grow Curved Leaf Yucca

First, choose an appropriate location for the plant. Curved leaf yucca is a large evergreen shrub that grows 6 to 10 feet (1.8 to 3 meters) tall. Full sun is best in most regions, but in very hot locations like the American Southwest deserts, this plant should be shielded from intense sun by placing it in partial shade. A curved leaf yucca growing in a well-drained soil will be healthiest and look its best.

Curved leaf yucca care includes regular watering; although the plant is drought tolerant, it will look its best if kept watered. Pruning is not necessary or beneficial, except that dead leaves should be removed at their base.

Spider mites may infest the plant and should be washed away by hosing down the plant. Propagate curved leaf yucca by seed, by division, or by making short cuttings from the stem.

How to Grow Yucca recurvifolia Plants in your Garden

Yucca recurvifolia is an ornamental evergreen shrub native to the southeastern United States.

Commonly known as curve-leaf or pendulous yucca, this large, vase-shaped plant is a cultivar of Yucca gloriosa and a member of the Agavaceae family.

The plant's long, thin leaves are semi-flexible, growing upwards from its center and gently fanning downwards so that the lowest leaves touch the ground.

Each blue-green leaf ends in a sharp point, and the central stalk can grow upwards of six to ten feet tall (1.8 to 3 m high).

Mature Yucca recurvifolia bloom in late spring and early summer, growing towering spikes that hang with dozens of white, bell-shaped flowers.

Often used in landscaping due to its distinct architectural qualities, shrubs also do well indoors planted in decorative containers.

Reasons Why Your Yucca Plant Might Be Dying

First, we’re going to take a close look at the potential causes of your yucca plant’s troubles then we’ll tell you how you can identify and solve them. You’ll be happy to know that, in most cases, your yucca plant can make a quick recovery with a few small changes!


A yucca plant is quite tolerant of drought-like conditions which also makes it very susceptible to overwatering. Simply put, your yucca plant probably doesn’t need as much water as you think it does.

If your yucca is overwatered, you might notice that it has generally yellow leaves, root rot, or a trunk that feels spongy. In the early stages of overwatering, simply cutting back on watering and letting the plant and soil dry out is sufficient. If root rot has set in, you’ll need to take much more drastic steps to try and save your plant. Read this article to learn how to identify and fix root rot for more info.

Yuccas only need to be watered once the soil has almost completely dried out. Don’t water your Yucca on a schedule, but assess the plant and the dryness of the soil before deciding whether to water it or not. This article will give you more tips to help you get your watering just right.

It’s really important to allow the water to drain properly so that it doesn’t sit in the bottom of the pot for too long and damage the plant. This means that you have to use a pot with sufficient drainage. Ensure that the moisture can drain out of the pot naturally. Next, do not use a pot that is too big. A large pot allows the water to remain in the soil for longer than is necessary.

Cold Or Heat Stress

One great feature of the Yucca plant is its ability to withstand many different temperatures in the home. Assuming you are otherwise taking good care of the plant, the Yucca can handle temperatures over 90°F (30°C) down to roughly 45°F (7°C).

Outside of this range, though, is where you might get into trouble. If you notice leaf spots or leaf disfiguration, it might be due to stress from the temperature. Be sure to keep your yucca in an acceptable temperature range. If you live in a colder climate, remember that this is not a plant you can keep outdoors all year round.

Low Light

The yucca plant needs sufficient sun to survive. If your yucca plant is dying, one of the top reasons may be that it is not getting enough sun.

Outdoors, yucca plants thrive in full sun. That said, it is a popular indoor plant as well. If you keep your yucca in the house, place it in a spot that gets a lot of sun. A south-facing window is best. Choose one that gets as much unobstructed sun as possible. Generally speaking, the more sun, the better, especially if you are growing your yucca inside.

Believe it or not, the first sign that a yucca plant is not getting enough light is that the leaves become greener. The plant makes more chlorophyll to compensate for the lack of a natural light source. Shortly after this, though, the leaves start to yellow and will eventually fall off.

Luckily, this problem has a very easy solution. Move your yucca near a window where it will receive more sun. If this was the cause of your problem, your yucca should heal itself pretty quickly.

Sunburn From Excessive Direct Sunlight

As with anything, there is a balance to be had and, even though yuccas love the sun, it is possible to have too much of a good thing.

With the yucca plant, this can happen when they are abruptly moved from an indoor environment to the harsh, outdoor sun. Plants adapt to their environment so if the yucca gets used to a certain amount of sun and is then abruptly moved into the full sun, it may cause damage.

You might notice that the leaves become burnt which appears as yellow and white spots. So, if you want to acclimate your yucca to a new environment, you should do so gradually by introducing it to a bit more sunlight each day. Over time, it will adjust.

Insufficient Or Excessive Fertilizer

Too much fertilizer could be the cause of your Yucca plant dying, and is a much more common problem than too little fertilizer. Yuccas have slow growth patterns and do not need a lot of fertilizer, so it is much more common to have problems due to excessive fertilizer.

You should ideally only fertilize your yucca plant a few times a year. A balanced fertilizer is best. I recommend using either a water-soluble or liquid fertilizer, made up at half the recommended strength. Fertilizing every 2-3 months during the growing season should be more than sufficient.

If you have been applying excessive fertilizer, this will result in fertilizer burns and a sickly plant. Look out for the following signs your yucca plant is dying from excessive fertilizer

  • Brown leaf edges and tips
  • Slow growth
  • Leaf drop
  • Wilting leaves and yellowing of lower leaves
  • Slow to no growth.
  • A build-up of fertilizer salts in the soil

The best measure against this is caution. Be very sure not to over-fertilize your plant. If you think over-fertilizing is the cause of your Yucca plant dying, flush the soil with plenty of water. This helps leach excessive fertilizer salts out of the soil. Avoid repotting a stressed plant, as this can often create additional stress for your plant.

Read my guide to fertilizing houseplants for more information about how to get this important aspect of plant care right.

Transplant Stress

Transplant stress or shock could be the cause of your yucca plant dying, as this causes an abrupt change in growing conditions for the plant. In this situation, some of the roots may die and they will no longer be able to support the yucca. You might notice the plant starts to wilt, stop growing, and generally look a little sad when this happens.

What you should do in this situation is to always be sure to properly transplant or repot your yucca. Pick a proper sized pot based on the size of your yucca that allows the roots to grow large enough to support the plant. This process should be based on the needs of your specific yucca plant.


The yucca plant is a relatively low-maintenance plant and, luckily, that usually extends to pest problems. This plant doesn’t get pests very often and, when it does, it is usually an easy fix. There is a small chance that your yucca can die from a pest infestation but that chance is low.

Regardless, you should be on the lookout for these pests in your yucca plant:

  • Aphids: Aphids might be found eating the leaves on your yucca plant. You can rinse them off with some water, or try using insecticidal soap or horticultural oil weekly until controlled.
  • Mealybugs: Mealybugs leave waxy markings on your yucca plant which are easy to spot by their white filmy appearance. Rubbing alcohol, horticultural oil or insecticidal soap are good treatments.
  • Scale: Scale are hard-armored pests that could overrun the leaves of your yucca. They appear as hard bumps. These can be manually removed, or treated with rubbing alcohol, neem oil or horticultural oil quite effectively.

If you need to get rid of pests on your Yucca, or any of your houseplants, I’ve used the following treatments with great success. Click the links below to see on Amazon.

  • Horticultural Oil
  • Neem Oil
  • Rubbing Alcohol

Overall, you probably won’t have too many problems with pests on your yucca but it is an important thing to look out for.


A yucca plant is susceptible to a few diseases that may be responsible for poor health. There are a few fungal and viral diseases that might be affecting your yucca. Learning to identify and treat these diseases can help your yucca get back to good health.

Fungal Disease: You can often spot a fungal disease by the effect it has on your yucca’s leaves. The disease often causes spots on the leaves of your plant because spores from fungi thrive in the water on the yucca’s leaves. For this reason, you should be extra careful not to overwater your yucca plant. If needed, you can purchase a copper fungicide to address a fungus infection.

Blight: Blight is another condition that can affect yuccas. It can cause dark spots on the plant and, because it is spread in the water in the soil, you can let the plant heal by drying it out.

As you can see, many infections and diseases are caused by excess water. The yucca plant does not need a lot of hydration so be careful to avoid overwatering.

Yucca plants require full sun and sandy, well-drained soil. They are drought-resistant plants, needing additional water only until they are established. Fertilizing is generally not necessary, although young plants can be fed to encourage initial growth with a half-strength solution of a well-balanced fertilizer.

Use a hose or watering can to water near the base of a yucca rather than from overhead. The less the foliage is exposed to water, the less likely that it'll have fungal problems. If you must water a yucca from overhead, water in the morning so that the foliage dries out before night.
