Grow yucca in full sun and soil that drains. Adam's needle is the hardy garden kind.
Give it full sun, soil that drains, and skip winter wet
| Factor | Recommended | Avoid |
|---|---|---|
| Sun | Full sun, at least six hours | Do not site it in deep shade |
| Soil | Sandy or gritty ground that dries after rain | Do not leave it in a low spot that stays wet |
| Water | Water a new plant; then let the soil dry | Do not keep the crown wet in winter |
| Feed | Little or none | Do not pack rich, wet compost against the leaves |
Yucca is an evergreen clump or a small tree with sword leaves. Give it full sun and soil that drains. Once the roots take, it tolerates dry spells. Soil that stays wet around the crown leads to rot and leaf spotting. [1] Hardier kinds such as Adam's needle and Color Guard want that same sun and drain. [2] Pick a kind on Types of Yucca.
- Site it in full sun. Light shade is tolerated; bloom and color are weaker there.
- Keep the crown high and dry. On clay, mix in grit or plant on a slight mound. [3]
- Water to settle a new plant, then wait until the soil is dry. Skip extra water in cool, wet weather. [4] A nursery plant goes in the ground on Planting Yucca.
- Wear gloves. Sharp tips belong off a walk and away from where children play.
Does yucca need full sun?
Yes. Give it at least six hours. Shade makes the clump stretch and bloom poorly.
How often should I water yucca?
Water a new plant until it roots. After that, water when the soil is dry. Do not leave the crown in standing water, especially in winter.
A spineless cane such as giant yucca is a houseplant, not a hardy needle you leave in a wet bed. Keep that plant on Yucca in Pots.
Not cassava, not an agave, and not red yucca
Yucca is the sword-leaf plant. Yuca, with one c, is cassava — a tropical food crop with a swollen root, not this garden shrub. An agave has thicker succulent leaves, and most kinds bloom once then die. An aloe is a softer, fleshy rosette. Desert spoon has a grassy fountain, not a stiff yucca sword. Red yucca is Hesperaloe: grass-like leaves and coral tubes, not a white yucca panicle.
Is yucca the same as yuca?
No. Yucca is this sword-leaf plant. Yuca is cassava, a different crop.
Is yucca the same as agave?
No. Agave has thicker succulent leaves, and most kinds bloom once. Yucca usually blooms again.
Is red yucca a yucca?
No. Red yucca is Hesperaloe. It has grass-like leaves and coral tubes, not a white yucca panicle.
If the crown stays wet after rain, move the plant onto draining ground and stop extra winter water.
FAQ
Does yucca die after it flowers?
Most garden yuccas bloom again. Our Lord's Candle often dies after that rosette flowers, then offsets may take over.
Is yucca toxic to pets?
Yes if eaten. Saponins in the leaves and roots can make dogs, cats, and horses sick. Keep chewing pets away from the plant.
Why do yucca leaves spot?
Wet soil around the crown is the usual cause. Improve drainage and skip extra winter water. Do not start a spray program until the soil dries.
Is a yucca palm a palm?
No. Yucca palm is a nickname for a trunked yucca. It is not a true palm.
Can I eat the flowers?
Some people cook the flowers. That is not the garden job here, and yuca in a grocery bin is cassava, not this plant.
