Milk spray

Combine 1 part milk (preferably organic) with 9 parts water and use immediately as a preventative spray against fungal diseases such as powdery mildew on cucumber, pumpkins and zucchini.


This by-product of sugar refining acts as a deterrent to feeding for caterpillars and other leaf-eating pests. Dissolve 2 tablespoons of molasses in a little hot water and then make this up to 1 litre by adding cold water. Add 1 teaspoon of liquid soap. Spray over the leaves of any plant attacked by caterpillars. Use within a week.


Add 100ml of vegetable oil to 20ml of liquid soap in a jar or bottle with a secure lid. Shake vigorously until well blended. Label and store in a cool spot where it will keep for several months. To use, shake well and then add 1 tablespoon of concentrate to 1 litre of water and spray. Don’t use on hot days when it can cause leaf burn.

She-oak spray

Gently boil 100g of she-oak (Allocasuarina or Casuarina spp.) needles with 1 litre of water in a covered pan for about 20 minutes. Cool and strain. Use within a few days to treat bacterial wilt.


Add 1 teaspoon of soap flakes or ecologically friendly laundry or dishwashing detergent to 1 litre of water. Do not apply more than once a week for a few weeks as it can damage plants and leave a residue in the soil that kills beneficial soil creatures. Commercial potassium-based soap sprays do not leave a residue so can be used more often. Soap sprays are used to treat a wide range of pest problems including scale.


Pour 1 litre of boiling water over three firmly packed cupfuls of roughly chopped leaves from Artemisia absinthium, A. arborescens or A. pontica. Leave to cool, strain and dilute with twice as much water. Use within a few days.
