- 1 gal. of warm water,
- 1 cup of instant coffee crystals,
- a squirt of dish soap(not detergent),
- several dashes of tobasco sauce.
If you make kess than a gallon you could just throw it awy and start new in the Spring.
Do Not Use Instant Powder Coffee; it won't disolve well.
The soap is a surfacant which helps insecticide stick to the leaves. I think the key may be the tobasco sauce. Good Luck.
- 2 tsp. baking powder
- 1/3 cup rubbing alcohol
- 1/4 tsp liquid dish soap
You will be amazed at how fast this knocks out unwanted pests.....before your eyes!
I would suggest you do this very early in the morning as to not burn your plants in the heat of the day.
You have to repeat this as you see the return of the unwanted pest, but it is safe, easy and works great ... I have not found any insect that it will not kill, with direct contact. I also see that it keeps them away for a period, depending on water and rain fall.This is safe and can be applied same day as harvest, just rinse well.
- Garlic Concentrate (this can be bought at gardening supply stores)
Another option is to use certain kinds of plants strategically to drive unwanted bugs from your more delicate varieties. Called 'companion planting', this approach aims to leverage plants' natural properties for use in your garden. Popular companion plants are marigolds, 4 o'clocks, nasturtiums, garlic, borage and tansies.
