Neem is a fast-growing tropical tree, kept as a tender container plant in cold climates and brought to the sunniest spot indoors over winter. It is the source of neem oil, the garden insecticide, but the potted plant earns its place on the fine, feathery evergreen foliage alone.
Give it the brightest window in the house and keep it warm — it slows and sheds leaves below about 50°F. Let the top inch of soil dry between waterings; it resents both drought and soggy roots. Prune in spring to hold it to a manageable size, and stand it outdoors for the warm months once nights stay above 50°F.
Wants the brightest, sunniest window you have — several hours of direct sun. In low light it drops leaves and grows thin, weak stems.
Putting it outside for summer? See its garden profile — hardiness zones, bloom window, and when to bring it back in.Water thoroughly until it drains, then empty the saucer — never leave it standing in water
Low — keep to a consistent rhythm and don't let it dry out hard.
Foliage is not considered toxic — neem is long used in traditional medicine. Neem oil is a topical and garden product, not for eating.
Water once the top inch of soil is dry
Feed with a balanced houseplant fertiliser
Prune to shape and control size
Check leaf undersides for spider mites in dry indoor air
Repot as it fills the pot — it grows fast
