  The effects of cold

  Cold weather, particularly frost, causes the water in plant cells to freeze, damaging the cell wall. Frost-damaged plants are easy to spot, their growth becomes limp, blackened and distorted. Evergreen plants often turn brown and the leaves of tender plants take on a translucent appearance. Frost problems are often made worse where plants face the morning sun, as this causes them to defrost quickly, rupturing their cell walls.

  Hardy plants and tough evergreens can also be damaged by prolonged spells of severe cold when soil becomes frozen. Roots are unable to take up water and plants die from lack of moisture. Periods of cold, frosty weather during April and May can also kill blossom and damage fruit.

  Minimising damage

  Prevention is far better than cure, so try to minimise the damaging effects of cold on your plants:

  ·         Avoid golden or variegated plant varieties that are often more tender.

  ·         Choose plants that are reliably hardy in the area where you live.

  ·         Avoid high-nitrogen fertilisers as they encourage plants to make lots of sappy leafy growth that is particularly susceptible to                damage, especially early and late in the year.

  ·         Make sure tender specimens are planted in a sheltered spot, under large trees and shrubs or against walls, give them some                  heat and protection during the winter.

  ·         Ensure that plants with tender flower buds or shoots are not planted in east-facing sites.

  ·         Leave the old growth of tender plants unpruned over the winter months. This will help to protect the central crown of the                 plant and take the brunt of any frost damage. If plants are cut back hard in autumn new growth could be damaged by frost.

  ·         Cold air and frost always descend to the lowest point in a garden so avoid planting tender plants in obvious frost pockets.
