Agave

Agave americana · Succulent

A bold rosette of thick, sharp-tipped leaves that stores water and shrugs off heat and drought. It grows slowly, flowers once after many years on a tall stalk, then the main rosette dies while offsets carry on.

When?

Plant or repot in spring or early summer when growth starts. Outdoors, plant only where winters are dry and mild enough for the species.

Step by step

1. Wear thick gloves; leaf tips and edges are sharp.
2. Use a pot with a drain hole and fill with cactus mix plus extra grit or pumice.
3. Set the rosette at the same depth; do not bury the leaf bases.
4. Wait a week before the first watering to let damaged roots heal.
5. Water deeply, then let the soil dry completely before watering again.
6. Feed with a diluted cactus fertilizer once or twice in summer at most.
7. Remove offsets (pups) with some root and pot them up separately.
8. Trim the sharp tips if children or pets pass close by.

Common problems

Pets

Sap and leaves are harmful to cats and dogs and can irritate the mouth and skin; the spines can also injure. If in doubt, ask your vet.
