Rhubarb Aphid/Fungus Spray

When harvesting rhubarb, the poisonous leaves are often discarded in the compost. While this is a great place for them, they can also be recycled in another way - making a spray that repels soft-bodied insects, such as aphids, and helps reduce fungus in the garden. The spray can also be used to lower the pH of the soil: just pour the blend anywhere you require a little more soil acidity.

Here's how:
Place three fresh, chopped leaves in a 4-L (16-cup) pot of water, bring to a rolling boil and turn off heat. Let sit overnight, then strain. Discard leftover bits in the compost pile. Place liquid in a spray bottle and label. Spray plants thoroughly at the first sign of aphid or fungus infestation. Make a new batch and repeat in 10 days.

Important: Rhubarb leaves are poisonous so do not use on edible plants. Be sure to wash all kitchen equipment thoroughly after making the spray.
