This was SO easy - and SO SO effective! It is totally non-toxic and organic (depending on the products you choose).
1 and 1/2 tsp of Extra Virgin Neem Oil
1/4 tsp of soap (any soap you use is fine - you just need a tiny amount - I used some organic Ava hand soap)
24 oz of warm water
24 oz spray bottle
You will need to shake it each time you use it, but spray your plants late in the evening or in the morning, leaves, stems, etc. I did it right after a rain to ensure the oil wouldn't be immediately washed away... and have done it about once every 2 weeks since. The neem oil smells a little like old potatoes and onions, but doesn't affect the produce. Neem oil has lots of other uses too - so check out what else you can use it for!!
