Neem - grow it

Unfortunately you are unlikely to be able to grow this plant, as there are no suppliers of live plants or fertile seeds known in the British Isles. Neem can only be grown indoors in this cold climate, and does not fruit well in pots.

Hardiness

Neem will not grow outside in the UK - it needs a heated greenhouse or very warm window sill. Minimum temperature required is around 18°C
propagation icon

Propagation

From seed. Sow seeds in a pot, cover with 2-3 cm of compost and keep warm inside a sealed plastic bag: germination should take about 3 weeks at 20°C.
cultivation icon

Cultivation

Pot on seedlings, once large enough, and move into bigger pots as needed. Neem responds fairly well to being trimmed and can be grown in a 45cm pot for some years in a heated glasshouse. Prune over large plants in spring, and lightly prune again in August if necessary. Water plants well in the growing season and feed fortnightly using a general liquid feed.
