Easy the first year; flowering again depends entirely on how well you feed the leaves after the flowers fade.

Care

Light

A bright window while growing; turn the pot to keep the stem straight.

Water

Sparingly until the stem shows, then medium while in leaf; dry from late summer for the rest period.

Soil

Loam-based compost with grit, in a pot just 2-3cm wider than the bulb.

Pruning

Cut the flower stem off near the bulb once faded, but keep the leaves: they feed next year's flowers.

Feeding

A high-potash liquid feed every two weeks from the end of flowering until late summer, to build up the bulb.

Propagation

Offset bulbs detached when repotting in autumn take two or three years to flower.

Month by month

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