If you are struggling to save your plants and vegetables from aphids, below are some tips that I have found useful. Hopefully, you are lucky enough to have an aphid-free garden...
Mix the following ingredients in a spay bottle:
1 cup vegetable oil
1 1/2 cup warm (not hot) water
2 teaspoons dish soap
Spray the entire plant vigorously to knock off as many aphids as possible. You want to clean the plant as much as you can with plain water first. The more aphids you can knock off, the better.
Spray the plant with the vegetable oil & soap solution outlined above. Be sure to spay under leaves and concentrate the spray on areas that have new growth. The soap will wash off the aphid’s protective coating and will cause fatal dehydration. The treatment will start to work in minutes.
The vegetable oil & soap mixture can be sprayed once a week, or when aphids are visible. You can identify aphids by looking for small lice-like bugs on trunks, leaves, stems and branches. Common aphids are green, but they can also be yellow, red, brown and black depending on the species and plants they feed on. A sign that you have aphids will be a waxy liquid on leaves; this is the area where aphids are feeding.
Try and avoid using the vegetable oil & soap solution on very hot and sunny days. Oil build-up can magnify the sun and possibly burn leaves and harm the plant.
