i have a little space contained by my backyard where i am currently growing a variety of fruit, herb, and vegetables. one of the vegetables i am growing are bush beans and they getting eaten up and by what i do not know. does anyone know a safe and fluent way to i guess protect them?
look it up on google. i meditate you can spray viniger on them, but better say than sorry. I have hear that spraying beer on plants will kill aphids -
Place a clove of garlic in a blender and add 500 ml (2 cups) of marine. Blend until smooth. Pour the liquid into a container, cover and let sit for 24 hours. Filter through cheese cloth or a strainer. Dilute beside 4 liters (12 cups) of water and add one or two drops of insecticidal soap to formulate the mixture adhere to plant leaves. Spray on plants infested with spider mites, whiteflies, aphids or thrips.
Garlic-based insecticide is not a preventative. It act on contact, which means that it must touch the insect pest in decree to be effective. Hope this helps :) you could try to spray Lemongrass grease around the plants, it's a natural bug deterrent like Citronella.
Answers:    Spread corn meal on the soil around the underneath of the plant. I don't know how it works, but it works. You can also plant lemon grass around your plants. I've also used mild detergent and water in a spray bottle for aphids and webwowms. I hope this help!
A garlic based spray is virtuous.
