Will annual clover invade other areas of the yard? I have literally been on my hands and knees to dig the white flowered clover from my lawn for the last three years. If there is an annual clover where would I buy it?
Yes some will. But as the article states, you kill it when you till it back into the soil. If you want a cover that you don’t have to till and will die over the winter use rye grass or oats. However, they grow best in cool weather so they may not work as well if you are harvesting in hot weather and replanting cover immediately.
Yes, just be aware that you will have extra nitrogen in the soil. So you do not want to add too much nitrogen fertilizer. If you add too much nitrogen the green beans will grow greenery at the expense of beans.
