This fresh-scented lemon pesticide is especially useful if your garden is inundated with aphids – those sap-sucking insects that do untold damage to your precious plants.
To make, simply bring a pint of water to the boil. Meanwhile, grate the rind from one lemon. Once the water is boiling, remove it from the heat and add the lemon rind. Allow to steep overnight before straining the liquid through a cheesecloth or fine mesh sieve. Pour this clear liquid into a spray bottle and apply to the top and underside of the leaves of the affected plant.
Note that the mixture must come into contact with the insects’ bodies to be effective.
