Here's the recipe my husband uses on our peach trees which suffer from leaf curl caused by insects. He also sprayed it on the tomato p!ants that had white fly. It is effective, and entirely natural.
Organic gardening is about using natural products to produce food that is chemical free. Using garlic water is a great way to maximize crop production without relying on chemicals.
Standard garlic water recipe:
6-cloves of garlic peeled and sliced fine.
2-quarts of tap water or purified water.
1 TBLS natural soap (castile is a good brand)
1 Spritzer bottle.
1 Mason Jar with lid ( recycled jar works fine too)
In a sauce pot, warm water until it begins to steam. Add sliced garlic and maintain temperature for 20 minutes. Allow water to cool, Remove garlic from water and discard (compost.) Add soap to spritzer bottle. Using a funnel add enough water to fill the spritzer bottle almost full but leave at least 1/2 inch of room. Put the lid on the spritzer bottle and shake slightly when ready to use. Spray plants early in the morning or in the evening time after the hottest part of the day has past. Several applications may be needed. Avoid using the spray on hot days as the liquid and sunlight may burn the plants. Extra liquid can be stored in the jar in the fridge for up to two weeks.
