Agave care guide

Agave

Also known as: Century plant

Pets and children

Caution advised

The leaf tips are sharp and the sap irritates skin and mouth; eating it can cause vomiting, so keep it out of reach and consult a veterinarian or doctor if swallowed.

How often to water Agave

Spring–Summer (Mar–Sep)
Every 7 days
A summer grower: as a guide, water deeply once the soil is dry all the way through, in the evening in midsummer.
Autumn (Oct–Nov)
Every 14 days
Cut back as it cools; as a guide, wait about a week after the soil dries before watering.
Winter (Dec–Feb)
Every month
Growth stops, so keep it nearly dry, moistening the soil lightly about once a month on a warm morning.

Light and placement for Agave

Best outdoors in full sun with good airflow year-round, as a guide; too little light stretches the leaves, and midsummer sun is generally fine unless the pot overheats.

Overwintering Agave

Overwintering guide: 0°C (32°F) or above

Hardiness varies by species, but generally it takes about 0°C if kept dry; shelter it from frost and winter rain under the eaves or at a sunny window, as a guide.

Fertilizing and repotting Agave

Fertilizer

It needs little: as a guide, a small dose of slow-release fertilizer or diluted liquid feed about monthly from April to September, and none from fall on.

When to repot

Spring–Summer (Mar–Sep)

Common problems with Agave

  • Grown in dim indoor light, the leaves stretch and the rosette loses its shape.
  • Overwatered in winter, the roots rot.
  • Water left standing in the saucer suffocates the roots.

Tips for growing Agave

  • Use a fast-draining mix so water runs straight through the pot.
  • Remove dried outer leaves at the base to keep air moving around the plant.
  • Wear thick gloves when repotting to avoid the spines.

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.
