Dennis Greville - Organic Sprays - 13 November
2 whole garlic heads
1 teaspoon kerosene
1 litre water
1 tablespoon grated soap (Lux Flakes or similar)
Crush the garlic with the kerosene. Boil the soap flakes in the water until dissolved. Cool, add the garlic and the kerosene mixture and strain. Keep this spray sealed in a bottle. Use against aphids and other insect pests. When required, dilute the mix at a ratio of 1:50 with water. The addition of a little conqueror oil at summer strength, or milk, will help the spray stick to foliage.
Baking soda mix
3 tablespoons baking soda
2.5 tablespoons horticultural oil
4 litres water
Mix ingredients. Use to combat powdery mildew and leaf spot; spray onto infected plants and reapply as often as needed.
Bicarbonate soda mix
3 level teaspoons bicarbonate of soda
2 good splashes fish emulsion, such as Oceanic Nitrosol (this helps the spray to stick while at the same time feeding the foliage)
Mix together in a 10-litre bucket of water and spray weekly
