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.
Things You Will Need
- Liquid soap, such as laundry or dish soap
- Crushed red pepper
- Fresh garlic
- Storage container with lid
- Test the mixture on plants that could be damaged by the soap mixture prior to applying it to the entire plant.
- Don't leave the soap mixture on plants for long periods of time. Rinse it off after three or four hours. The soap will have suffocated bugs on the plants, and odors remaining from the pepper and garlic will repel others.
