All-purpose, non-chemical, insect repellent for plants
Before reaching for chemical pest controls, try this simple formula you can make at home.
1 garlic bulb
1 small onion
1 tablespoon cayenne pepper
1 qt water
1 tablespoon liquid hand soap
Chop or grind garlic and onion, add cayenne and mix with water.
Let steep about an hour, then add liquid soap.
Put into a spray bottle and spray only affected areas.
This mixture will keep in the fridge for about a week.
(It is recommended to first test your mixture on a small part of the plant.)
