Spineless yucca care guide

Yucca gigantea

Also known as: Stick yucca, Yucca elephantipes

Pets and children

Considered toxic

Saponins in the leaves and trunk can cause vomiting, diarrhea, drooling, and unsteadiness; keep it out of reach and consult a veterinarian (or a doctor, for a child) if eaten.

How often to water Spineless yucca

Spring–Summer (Mar–Sep)
Every 7 days
Water thoroughly once the soil has dried through, as a guide; it tolerates drought, but constant moisture rots the trunk.
Autumn (Oct–Nov)
Every 10 days
As it cools, wait roughly four to five days after the soil dries.
Winter (Dec–Feb)
Every 20 days
Water sparingly about ten days after the soil dries; a drier plant stands the cold better.

Light and placement for Spineless yucca

Generally wants a sunny spot: a sunlit window indoors, or the open air from spring to autumn; too little light makes the leaves droop and fade and the trunk stretch.

Overwintering Spineless yucca

Overwintering guide: 3°C (37°F) or above

Fairly cold-tolerant, taking around 3°C; as a guide, move it out of frost under the eaves or to a sunny spot indoors, and keep it on the dry side through winter to avoid damage.

Fertilizing and repotting Spineless yucca

Fertilizer

Slow-release fertilizer about every two months from May to September is generally enough; it comes from poor soils and needs little, with none from October on.

When to repot

Spring–Summer (Mar–Sep)

Common problems with Spineless yucca

  • Overwatering rots the base of the trunk until it wobbles and falls.
  • In a dim room the leaves droop and yellow and the plant stretches.
  • Scale insects and spider mites move in when the indoor air is dry.

Tips for growing Spineless yucca

  • When it gets too tall, cut the trunk in spring and new shoots appear below the cut.
  • Let the cut top dry, then set it in soil and it roots.
  • It leans toward the light, so turn the pot now and then.

These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
