Q How should I plant lilies in pots?

A All parts of the lily are toxic to cats, so avoid growing them if you have cats as pets.
Although advice often suggests planting lilies in autumn, but many varieties are sold to be planted in spring, preferably by the end of March.
Plant the bulbs into deep containers leaving plenty of space for the roots and 15cm above the bulb to the surface of the compost. Use a Best Buy compost for containers and add granules of a controlled-release fertiliser.

Q How should I care for lilies in pots?

A Place the pots in full sun and ensure the compost is moist at all times, but not wet. Feed with a liquid fertiliser, such as tomato feed, every fortnight during summer. Repot bulbs in the autumn  when the foliage dies down, or transfer them to the garden. To overwinter the containers, place in a cool but frost-free, airy place.

Q Which pests and diseases can attack lilies in pots?

A Lilies can be affected by slugs, snails and grey mould. The biggest threat are bright-red lily beetles, whose excreta-covered grubs can strip a plant of its leaves, spoiling its look and reducing the vigour of the bulb.
