Please also note that dishwashing liquid is called for in most of these ‘recipes’. It serves as a ‘wetter’ enabling the liquid solution to adhere to the plant for maximum effect. The environmentally friendly non-toxic dishwashing liquid is ideal for this purpose.

Comfrey foliar feed
This is a good general purpose liquid manure and may be used on all plants.

Cut holes in the bottom of one of the buckets. Fill the bucket ¾ full with Comfrey leaves and pack down tightly. Put the plate on top of the leaves and weigh down with a brick. Place the flowerpot upside down in the second bucket and place the Comfrey-filled bucket on top of this. After 3 weeks there should be brown liquid in the lower bucket. Bottle the liquid and place the remaining wilted contents of the top bucket on the compost heap.
To use: Dilute 2 tablespoons of the Comfrey foliar feed in 2 litres of water; and add a little dishwashing liquid.
An alternative method of controlling powdery mildew is to spray weekly with milk dilute. Milk also acts as a foliar fertilizer and boosts the plant’s immune system.
Dilution: 2 parts milk to 9 parts water. Spray the affected plant weekly for good effect.
