How to grow

Cultivation Plant snowdrops in a partly-shaded position in a moist, but well-drained soil with leafmould or garden compost incorporated. It is important that the soil does not dry out in summer. This species comes mainly from north- eastern Turkey and eastern Georgia and southern Russia and is often found on chalk, but has a wide range of soils and conditions under which it grows. In the garden it is easy to grow and its leaves are a fresh green, making a change from the glaucous leaves of many other species

Propagation There are four methods that can be used to propagate snowdrops. Divide snowdrops 'in the green', Propagate by seed, chipping or twin scaling. Further bulb propagation advice

How to care

Pruning No pruning required. Allow the foliage to die back naturally

Pests Squirrels digging up snowdrops planted as dry bulbs may be a problem

Diseases Sometimes seedlings are lost through damping off which is caused by fungi and results in their collapse. Grey mould can affect snowdrops, especially in mild winters.
