Want to make your own botanical fruit tree spray? Here’s a recipe to try. While this spray is all-natural, it can harm beneficial insects like bees, so be sure to spray at a time when bees aren’t active (early morning and late evening). Keep an eye out for bird nests and avoid spraying near them. And remember, you wouldn’t want to get this in your eyes or on your skin, so handle it with care!

Garlic Fruit Tree Spray
Garlic is known for its strong scent, which can deter many types of pests, from aphids to caterpillars and even some types of fungi.
Ingredients:
- 1 pound of garlic
- 1 gallon of water (rainwater is best)
Instructions:
- Peel and Mince: Start by peeling the garlic cloves. Then, mince or finely chop them to release the essential oils. The finer, the better.
- Simmer: Combine the minced garlic with water in a large pot. Bring the mixture to a simmer (not a full boil) and let it cook for about 20 minutes. This process infuses the water with garlic's active compounds.
- Cool and Strain: After simmering, take the pot off the heat and let it cool. Once it's cool, strain the mixture to remove the garlic pieces. A cheesecloth or a fine mesh strainer works great for this. You want the liquid as clear as possible to prevent any sprayer clogs.
- Dilute (Optional): Depending on what you're dealing with, you might want to dilute the mixture. A common approach is to dilute the concentrated garlic water with more water. This step is adjustable based on your needs and the sensitivity of your plants.
- Bottle Up: Pour the strained, cooled liquid into a spray bottle or a larger sprayer for application. It’s ready to use!
- Apply: Spray it on the leaves of your fruit trees, covering both the tops and undersides where pests like to hide. Early morning or late afternoon is the best time to apply, avoiding the hot midday sun to reduce the risk of burning the leaves.
Tips:
- Storage: You can store the garlic spray in the refrigerator for up to a week. For longer storage, freeze it in an ice cube tray and thaw cubes as needed.
- Test: Always test the spray on a small area of the plant first to ensure it doesn't react badly.
- Reapply: After rain or watering, you might need to reapply, as it can wash off.
