Next time you pick some rhubarb stems to eat, you can put the leaves to good use rather than just composting them.
The leaves contain so much oxalic acid and anthraquinones that they are poisonous to eat, but they make a good inseticide spray. Rhubarb roots should be considered poisonous, too, unless used by a skilled practitioner of traditional Chinese medicine. . If the plant is subject to extreme cold, the dangerous acid can migrate into the stalk, so be sure to store rhubarb in a warm or temperate space, just like the climate it normally grows in.
Rhubarb leaves can be used to make an effective organic insecticide for any of the leaf eating insects (cabbage caterpillars, aphids, peach and cherry slug etc).
- Basically you boil up a few pounds of rhubarb leaves in a few pints of water for about 15 or 20 minutes,
- allow to cool,
- then strain the liquid into a suitable container.
- Dissolve some soap flakes in this liquid and use it to spray against aphids.
Keep away from pets and children.
