Homemade Insecticidal Soap
To eliminate the cost and more importantly the use of chemicals in your garden, why not make a great homemade insecticidal soap.
This is a very lazy recipe. Two tablespoons of your favorite dishwashing detergent to one gallon of water. Pour in a spray bottle and you are good to go.
A drop or two of cooking oil can be used to make the soap stick if you'd like. Not entirely necessary.
Be sure to spray both the top and the bottom of the leaves. And do not spay in the heat of the day because sun scald might occur.
This is an excellent preparatory spray for bringing in houseplants for the winter.
