Yucca cultivation isn’t limited to the home. The sword-like leaves of the yuccas plant offer a distinctive look to any place, especially the landscape. There are multiple species of this perennial, evergreen plant. Let’s look at yucca landscaping and how to care for yucca plants in your yard.
Do yucca plants come back every year?
Yuccas flower only once a year, from the middle of summer to the beginning of autumn, depending on the variety. Adam’s needle yucca, for example, blooms from June to July, but Spanish dagger (Yucca gloriosa) blooms from July to August. Once a yucca has reached maturity and bloomed, it will usually bloom at the same time every year. On long spikes, all forms of yuccas produce similar inflorescences, but certain varieties, such as aloe yucca (Yucca aloifolia), have blooms that entirely cover the spikes, creating a particularly stunning display. If left uncut, yucca flower spikes can last up to two years after flowering before becoming an ugly brown. When flowering has finished, you can remove them.
Do yucca plants survive winter?
Yucca plants are usually fairly hardy in the winter. If it gets dry in a container, you’ll need to water it during winter. Prior to a strong freeze, pay special attention to water requirements. Wrap the container to protect the roots if exceptionally cold temperatures are expected. Otherwise, I believe it will work out perfectly.
Q We’ve been hearing a lot about planting native plants, and I’ve started doing it myself. What, on the other hand, would be an excellent flowering, pollinator-friendly native tree? I’m guessing dogwood, but what else could it be?
A There are several beautiful native trees that are great for pollinators in a variety of sizes. Consider an American basswood or “Little Leaf” linden for a larger shade tree. They attract bees when they are in bloom. Sourwoods are a tiny tree with summer flowers that pollinators love, as well as beautiful fall foliage. Blooming trees such as redbuds, magnolias, and serviceberries are beneficial to pollinators. The tulip poplar is another enormous shade tree, but it can grow to be over 100 feet tall.
Q My query concerns a Japanese maple that I grew from a seedling when my husband and I relocated to a retirement community in Fayetteville. Before we relocated to our current cottage, I planted it in a pot when we were temporarily living in a larger home. I honestly don’t recall whether it ever turned red in the pot, but it has only turned red in the fall since I transplanted it to its current position 10 years ago (it’s gorgeous right now). Is this due to the fact that it grew from grafted rootstock? It’s in a spot that doesn’t get much sunlight.
Japanese maples do not produce true descendants from seed. Summer and fall colours will have a lot of variation. They germinate quickly. You could graft a preferred cultivar onto the root stock of your seedling if you can get a cutting from it. The majority of Japanese maples are grafted.
Q We’ve been raking a lot in our yard and have several bags of pine needles. Is it okay to use pine needles as a mulch for flower beds?
In flower beds, pine straw mulch is fantastic. I avoid using it in vegetable gardens since it takes a long time to break down and can cause the soil to become acidic. Pine straw is very beneficial to azaleas and other acid-loving plants.
Q My neighbor’s crape myrtle has already been decimated. I don’t intend to be as harsh, but is it the right time to prune them?
A Crape myrtles should not be pruned until late February, and I never promote crape murder! I prefer to wait before pruning because the plants will be less exposed if we have a bad winter. If you trim them back now and we get bad weather in winter, you will have to chop away additional dead wood or risk losing the plant to the soil line.
How do I keep yucca over winter?
The easiest strategy to help a yucca plant survive a frost or freeze is to make sure the yucca plant receives as little harm as possible.
To avoid frost and cold weather damage, cold-sensitive yuccas must be sheltered. If the weather has been warm and a sudden cold period occurs, hardy yuccas may require protection. The yucca plant hasn’t had enough time to prepare for the cold and may need to be protected for a while until it hardens up.
Start by covering your yucca with a fabric sheet or blanket to keep it warm. Avoid utilizing synthetic materials and NEVER use plastic that comes into direct contact with the plant. During cold weather, plastic contacting the yucca will harm the plant. You can cover your yucca with a sheet and then cover the sheet with plastic if you foresee damp weather.
If you expect more than a little frost, you’ll need to take extra precautions to protect your yucca from the cold. Wrapping the yucca plant in non-LED Christmas lights or inserting a 60-watt incandescent bulb before covering it would help keep the cold at bay. Before covering the plant, place gallon jugs of hot water at the base to assist keep the temperature higher overnight. Multiple layers or thicker blankets may be required in colder weather to keep the temperature consistent for the yucca plant.
Are yuccas annuals?
The Yucca genus (Yucca spp.) is a mounded rosette of roughly 40 drought-tolerant perennial plants. Yuccas, which are members of the agave family, feature sword-shaped, grayish-green evergreen leaves that can be soft and pliable or hard and pointed. Yuccas grow stiff stalks topped with white flowers that are pollinated by the yucca moth in late spring and early summer. Yuccas are native to North America’s arid regions and are frequently linked with the desert. If cultivated in the correct conditions, they are low-maintenance plants.
What is the lifespan of a yucca plant?
Could you please identify this plant for me? It split in half shortly after this photo was taken during a windstorm. I had intended to replant part of it in a different location. Now I’m wondering if it’s nearing the end of its useful life and whether I should spend the money.
Yucca recurvifolia or pendula is the plant in your photo. Yucca pendula can reach a height of around 6 feet and takes about 10 years to reach that height. It has a lifespan of approximately 20 years. Yucca pendula often forms a huge clump and rarely branches. I’m guessing yours is close to a decade old.
Comments from readers: Two readers have responded to a previous column’s question (Nov. 1 column) about bougainvillea leaves being eaten:
– You said it looked like a carpenter bee. I’ve been growing bougies for over 30 years and have never had a carpenter bee attack them. The eating of bougies and tacoma by sesame leaf rollers has been a problem for me. I give them Bt (Bacillus thuringiensis, an insecticide) on a daily basis, and it appears to help. I’m wondering if this is the writer’s problem.
– I mentioned your sesame leaf rollers article (see note below). The small green worms on my bougainvillea were finally discovered. For the past two weeks, I’ve been spraying on and off, but I couldn’t figure out what was causing the problem. My leaves have holes, lace, and plant pieces that have been eaten away. Several folks in Pebble Creek, in the West Valley, have complained about the same plant. That made me question if that was the basis of the lady’s difficulties. I was told to use Severin by the staff at Lowe’s, so I sprayed it on and found a worm three days later.
The insect got its name from the fact that it is a major problem in India, where sesame is commercially farmed. The sesame leaf roller was initially discovered in October 2011 in Baja, Mexico, and again in April 2012 in California.
This species is native to a tropical environment. It will hopefully vanish with a frost.
If you wish to get rid of this caterpillar, use Bt and cover all of the plant’s surfaces, including the undersides of the leaves. The item is available at your local garden center. Always read and follow the directions on the label.
Do yuccas spread?
Yuccas are drought-resistant and low-maintenance plants. The main stalk of the Yucca plant sends out rhizomes, which help the plant to grow. The rhizomes produce new plants, which is why yucca spreads so quickly that it is considered a pest by some. Cutting the rhizomes with baby plants from the main root is one way to propagate yuccas. The same concept applies to dividing yuccas to regulate their development. Because the yucca plant can jam itself with too many clumps packed closely together, it’s vital to thin it out by dividing it as it grows.
Should yucca plants be cut back?
Pruning a yucca is best done just before it enters its growth stage, as it is with most plants. This will take place in the early spring. Although early spring is the best time to trim a yucca, it can be done at any time. Simply ensure that the yucca plant receives plenty of light while it recovers.
How do you take care of a yucca plant outside?
When pruning or removing yucca plants, make careful to wear protective chain mail or very thick gloves because their spiky foliage can easily slash off a finger!
How to Care for a Yucca plant
- Outdoor Yucca plant care: Yucca plants prefer dry soil with full sun exposure. Overwatering the plant might cause the roots to rot, so be careful.
- To maintain the plant tidy, remove all of the dead leaves. Wear thick gloves to protect your hands from being cut by the leaves.
- Yuccas dislike being relocated, so make sure you pick the correct spot before planting them.
- Yuccas thrive in low-nutrient environments and are light eaters, so a once-a-year feeding is sufficient.
Pruning Tips
- Yuccas, like many other plants, benefit from pruning just before they begin to develop, which is normally in early spring, though it can be extended to the beginning of summer.
- To maintain a clean appearance, the flower stalks must be cut once the blossoms have faded.
- Cut the stalk off at around 7 to 10 cm (three to four inches) above where it had emerged from the main stem with sharp cutters or pruning shears.
Care For Potted Yucca Houseplants
Indoor yucca plant care: make sure the plant receives plenty of bright light. Yuccas are heavy in both their stem and foliage, so use sturdy containers.
If the soil feels dry, gently sprinkle water on top of the plant when watering.
Although yuccas do not like to be overwatered, a lack of water or a draught can cause the leaves to turn brown or yellow. It takes care of itself, with the exception of pruning a Yucca plant.
Apply a time-release fertilizer in a circle around where you expect the roots to be when growing outside.
Propagate Yucca Plant from Cuttings
When propagating, it’s best to utilize mature tissue (to avoid root rot) and to do it in the spring.
After marking the trunk, cut off the leafy top, remove all of the upper leaves, and put the trunk in potting soil with the end that used to have the leaves looking up.
Now move the pot to a shady location. Within two to three weeks of planting, the trunk should have rooted itself and will begin to generate new leaves.
Will yucca survive outdoors?
Yucca thrives on soil that drains well and can be in full sun, as it is a native of the southern United States. It can even tolerate temperatures as low as 10 degrees Fahrenheit (-12 degrees Celsius), allowing it to thrive in a variety of settings.
The creamy-white flowers bloom best in full light from mid-to-late summer, with some yucca reaching heights of up to 10 feet (3 meters) and leaves up to 2 1/2 feet (76 cm).
