You'll see some early bud movement on your fruit trees.
This is the time that fungal diseases can get established. As an alternative
to copper sprays try spraying with Condy’s Crystals. It is a salt which has an
oxidising effect. It has antifungal and antiseptic properties. Mix one teaspoon with
one litre of water and add a dash of liquid soap. The mixture will be vivid purple.
Spray on trees and around the drip line on the soil. You can buy Condy’s Crystals
from most garden Potassium Permanganate centres or chemists. It is sometimes sold as Kmn04
