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.
