How Fast Does Yucca Rostrata Grow?

Yucca rostrata grows slowly, taking around ten years to reach their maximum height. It will eventually become a significant focal point in your landscape. Growing Yucca rostrata is simple, requiring well-drained soil with tiny stones and sand. Yuccas that grow trunks thrive in alkaline soil but thrive in acidic soil.

Growing your Yucca rostrata in a pot will need to be repotted every four years. The plant is ideal for Mediterranean gardens and rocky slopes. They may even be grown in gravel gardens.

While it grows slowly, it does require constant watering at least once a week. The soil may dry out quickly during the growing season in the spring and summer. However, do not drown your plant by leaving it wet since this might cause root rot.

Watering can be reduced over the winter. However, the general guideline is to check the soil moisture before watering your plant.

The ideal temperature range for growing your slow-growing plant is 65°F to 74°F. Your plant can withstand temperature decreases of up to ten degrees Fahrenheit. Even so, we recommend covering your plant from the cold while it is below freezing.

Your tree-like Yucca can also withstand high humidity levels. You may grow it as an outdoor plant if you reside in USDA hardiness zones 5 to 10.

The leaves are bluish blue-green with yellow edges and waxy and tapering ends. Nonetheless, the Saphire Skies variety has a powder blue hue to it. In the spring, Yucca rostrata blooms with pale flowers on lengthy panicles.

It also bears yellow-orange blooming stalks that can grow to be 40 inches tall. These stalks can be quite messy and make it difficult to trim or remove the dead flower heads. Yucca rostrata also produces white-yellow flowers in mid-summer. These flowers resemble a puffball and come with a scent that resembles rotting meat.

The roots are long and fleshy. They may get to be about eight inches in diameter but are not as hardy as their leaves, which take a very long time to decompose after they fall off the plant.

Is Yucca Rostrata Hardy?

Yucca rostrata is a drought-tolerant plant. It can withstand droughts and extreme heat. Yucca rostrata is suitable for USDA hardiness zones 5 – 10. While these plants produce lovely clusters of white flowers, they are often planted for their powder blue foliage, which is stunning on its own or in combination with other plants.

When you first plant your Yucca rostrata, it may take some time for the roots to develop properly. Therefore, avoid overwatering your plant when you first receive it, as the tree may get root rot. Yucca rostrata is a good choice for container gardening because of its resistance to both drought and extreme heat.

When you do container gardening, use a good potting mix, such as one made of composted bark or composted animal manure mixed with sand or gravel. You can also use a soil-less mixture like perlite or sand if you prefer not to fertilize at all.

It should never be watered with tap water since it could encourage root rot. You may also use a manufacturer’s fertilizer. Just ensure to avoid over-fertilizing, or your plant will not do well.

Yucca rostrata will survive a light frost if it is below freezing, however, it is susceptible to freeze damage above freezing. The trees require minimal maintenance and are hardy enough to grow outdoors in zones 5 – 10 but can be started indoors if desired.

They require minimal sunlight and need to be protected from the cold. The potted Yucca begins to bloom after 5 – 6 years of growth, however, it can take up to 12 – 15 years for the plant to reach its full height of around 8 feet.

How Do You Care For A Yucca Rostrata Plant?

Yucca rostrata caring is simple if the proper growth conditions are provided. Other popular names for the plant are Big Bend Yucca, Blue Beaked Yucca, Beaked Yucca, and Silver Yucca. Growing Yucca rostrata is quite simple, and it requires well-drained soil with tiny stones and sand. Yuccas that grow trunks thrive in alkaline soil but thrive in acidic soil.

Yucca rostrata thrive in direct sunlight. These plants flourish near rocky slopes and ridges in their native habitat. Canyon bottoms and plains are also ideal habitats for the large bend yucca.

The more sunshine they get, the better they grow and thrive. Choose a location that will expose them to as much full sun as possible. Indoors, however, avoid placing it right next to a south-facing window.

Yucca rostrata grows best at temperatures ranging from 65° to 74° Fahrenheit. When it comes to frost tolerance, these plants can withstand temperatures as low as -10° F or -12° C. The following are the factors to consider when caring for Yucca rostrata:


Yucca rostrata requires full sunlight. However, they should not be placed in direct sunlight as they can scorch, especially if the plant is young and small. If you live in a tropical or hot climate, keep your plant under partial shade to protect it from scorching.

If your plant is young, attach a shade cloth to the windows of your home to protect the plant from direct sunlight. The amount of sunlight required by this tree depends on its age and size.


Yucca rostrata is drought resistant and does not require much water to grow well in its natural habitat. Let the plant dry between watering sessions. Water it deeply but avoid watering the leaves and flower stalks directly as this can cause rotting. If you are watering your yucca rostrata outside, water it once every one or two weeks during the summer months.

In winter, check to see if there is residual soil moisture before watering your plant again. The soil should dry out between watering sessions. Overwatering can lead to root rot and other problems with your tree’s health.


Yucca rostrata should be planted in well-drained sandy loam soil that is poor, dry, and alkaline. If you are planting your tree indoors, use potting mix or garden soil to plant it in, along with gravel and sand to keep it well drained. You can also use perlite to create the perfect mixture for your plant.

In their natural habitat, Yucca rostrata live in alkaline soil that is rich in minerals. This makes the soil very useful for the growth of other plants as well. You may choose to place Yucca rostrata plants near other plants because of this property in the soil.


Yucca rostrata can tolerate temperatures between 65° and 74° Fahrenheit, or 18° and 23° Celsius. However, it should not be exposed to temperatures higher than this range as it can dehydrate and begin to wither. Yucca rostrata can also tolerate freezing and snow in their natural habitat.

If you live in an area that experiences cold temperatures, dig a hole in the yard where you will be planting the tree with care. Keep the portion of the tree that lies underground slightly above ground level to prevent snow build-up on its branches during winter.


Yucca rostrata is a plant that thrives when it is humid. However, it does not like high humidity. Keep surface water from collecting on the leaves of your yucca to prevent rot and other problems. The humidifier in your home can increase the air’s humidity levels if it is too dry.


Yucca rostrata requires little or no fertilizer as it requires minimal soil nutrients and water. While feeding your Beaked Yucca is not required, a slow-release fertilizer can help it thrive. You may do this in the spring, but remember to water well afterward. During the growth season, you may trim it to remove old leaves or damaged foliage.


Yucca rostrata can be propagated from seeds or cuttings during the spring and summer. The seeds of the yucca are extremely small and are released in masses, so you will have to gather them up individually.

Seeds may not germinate well indoors, so try placing a pot outside in the soil and wait for the plant to spring up on its own. If you live in an area that experiences freezing temperatures or snow, wait until spring to plant it outdoors.

When propagating your Beaked Yucca from cuttings, use a sharp knife or pruning shears to take a piece of the stem that is 7- 12 inches long with at least two buds along it.


Yucca rostrata is ready for repotting. Set up your Yucca rostrata in a medium-sized pot filled with a specific indoor plant soil mix or green plant soil mix. Although it may be essential to repot it in the spring every 2 or 3 years, frequent topdressing should completely meet the plant’s growth media demands when not repotting.

When water runs straight through the container without touching the soil or when the roots are matted on top of the potting mix, it is time to replace the potting mix. Use a tree-shaped drainage hole in the center of the pot. Pruning:

Yucca rostrata should be pruned once a year, which is best done in the spring and summer. You may use a hand saw to cut dead or damaged branches. Remove dead branches and try to maintain the shape of the trunk.

You can also prune small branches that rub against each other. This tree must be maintained with regular pruning because it helps keep it looking good and healthy.

Pests and Diseases:

Yucca rostrata are vulnerable to disease, insect infestation, and pest damage. They tend to attract aphids, spider mites, and scale insects, which feed on sap. They also attract mealy bugs, white flies, and Tephritid fruit flies that affect your plant’s growth.

These insects spread plant pathogens and may cause your tree’s leaves to curl up or become discolored or spotted.

Yuccas are also vulnerable to fungal infections like Botrytis blight and powdery mildew. The fungus thrives in damp, cool conditions when the air is not circulating properly.
