My favas are gone. I pulled them up today. Though the lady bugs have arrived, the fava beans were just too stunted from black aphid damage to leave growing. (I almost pulled the adjacent pole beans too. These also have aphid damage, but seem to be recovering. I left them for now.) In place of the favas, I planted a mix of sunflower seeds.
I am glad to see the lady bugs, even though they are the big Asian type. They will help to control the green aphids on many of the plants in my garden.
