Could I just add to this thread my recipe for making a very good, organic & effective aphid killer?
You'll need 1kg / 2.2lbs rhubarb leaves, 2 litres / 67 fl.oz water and a few drops of washing-up liquid.
Place the rhubarb leaves into a large pot, add the water.
Bring to the boil and then simmer for 20 minutes to half an hour.
Strain off the leaves (and dispose with) allow the liquid to cool, then add a few drops of washing-up liquid.
The solution should be diluted 1 part solution and 9 parts water; in other words, add 9 litres / 2.3 gallons water to create a spray.
This spray should not be stored but should be used within 24 hours to achieve the best effectiveness.
