Organic gardening presents some extra challenges, including protecting plants from insects without using harmful chemicals. Basic liquid soap, especially when combined with a few other ingredients to repel a variety of plant-damaging insects, is a good alternative. When used in conjunction with beneficial garden insects, soap can keep most garden pests well under control. In some cases, it will even repel deer and rabbits, keeping your plants growing healthy and strong without using chemicals.
Place 2 tbsp. of crushed red pepper in a container that will hold at least 1 qt.
Chop two cloves of garlic.
Add the garlic to the container with the crushed red pepper.
Pour 1 tbsp. of liquid soap into the container with the red pepper and garlic.
Fill the container with 1 qt. of water.
Mix the ingredients thoroughly. The soap mixture is now ready to be sprayed on plants to kill and repel insects.
