Speaking of treating whiteflies, I saved this "recipe" several years ago. It was provided by a Duval County, FL Master Gardener and published in my local paper. Not only does it save you money, it is an environmentally friendly option to harsh chemicals.
Homemade Insecticidal Soap
- 2 tablespoons concentrated dish detergent
- 2 1/2 tablespoons vegetable oil
- 1 gallon of water
Combine all ingredients and pour into spray bottle. Spray all parts of the plant, including the underside of leaves. Repeat in 5 to 7 days, then as necessary.
Do not use soap sprays on gardenias or shrubs with sensitive leaves. If in doubt, spray a small area and check back in three to four days for damage to the leaves.
