Use a gritty, fast-draining compost from the start rather than standard houseplant compost, which retains too much moisture. Flowering indoors is a rare, occasional event on a mature, well-lit specimen — most Aloes grown as houseplants are grown for their form rather than for flowers, so don't worry if yours never blooms.

Care

Light

A sunny windowsill suits it well.

Water

Succulent, drought-tolerant; allow compost to dry out completely between waterings.

Soil

Free-draining, gritty cactus/succulent compost.

Pruning

Remove damaged or dying leaves at the base; offsets can be removed and potted up separately.

Feeding

Two or three weak feeds with a cactus fertiliser over the summer, no more. A well-fed aloe grows fast, pale and soft — the opposite of the tight, firm rosette that survives a windowsill winter.

Propagation

Detach the offsets that form round the base, keeping whatever roots come with them, and let any cut surface dry for a day before potting into gritty compost. Water sparingly until they are established.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.

Questions

Aloe: is it hardy?

H1c: Tender, needs above 5°C. It survives above 5 °C.

Can it grow in a pot?

An ideal windowsill succulent.

Aloe: when do you prune it?

Remove damaged or dying leaves at the base; offsets can be removed and potted up separately.

Aloe: when does it flower?

In the climate of UK it flowers in January–March.

When do you feed it?
