Winter wash pest and disease control on roses and fruit trees and bushes

Winter wash and tar wash

Application of tarwash or winter wash during the winter is now key with climate change to help keep your rose and tree trees and bushes free of pests and diseases during the spring and summer months. Winter washing will kill all the overwintering pests and pest eggs hiding in the buds on the bare stems in winter.

Applied once the plant has dropped the leaves in the autumn or winter on a frost free day. It is applied as a jet from a sprayer and allowed to run down the plant’s branches killing all the overwintering pests, eggs and disease spores. In the case of bacterial diseases it is important to remove as many of the fallen leaves as possible on the ground under the plant and treat the soil under the plant and mulch with a general mulch.
