Cut back frosted growth in spring to a healthy, new bud, to prevent further die back and encourage plants to produce fresh, new shoots.
Feed damaged plants with a balanced fertiliser (one with equal amounts of Nitrogen, Phosphorus and Potassium) to encourage strong, healthy growth. Dig up small, tender plants and take them into the greenhouse. Many will quickly produce new growth and recover, provided they are not subjected to prolonged periods of heavy frost, wet or cold.
Newly-planted specimens will often lift themselves proud of the soil surface if there is a hard frost straight after planting. Check them regularly and re-firm the ground around them to ensure their roots are always in contact with the soil.
The benefit of snow is that it acts as an insulator, protecting plants from the cold and frost, however, a heavy layer of snow can also cause leaves and branches to break, so it's important to know how to deal with it when it arrives:
Shake excess snow from the branches of large trees, shrubs and hedges, to prevent them from becoming disfigured by the weight.
Remove heavy deposits of snow from the roofs of greenhouses or cold frames to let in the light and prevent the structures from bending under the weight.
Use lengths of string to support the branches of conifers and stop them being pulled out of shape. Branches that move away from the main plant won't spring back into place when the snow melts.
Avoid walking on snow-covered grass as it will damage the turf beneath and leave unsightly marks on the lawn. It can also encourage the growth of fungal diseases which thrive in the cool damp conditions.
