I am very new to this forum. I have a blue pea vine in my terrace in a pot. The plant gives me good flowers, but during the summer some white pests comes and accumulates on the branches. After this all the leaves gets shredded and the plant looses it's charm. I manually remove these pests, and water the plant regularly. The plant returns to it's original state but the pests return back. Can anyone please suggest me what should I do?
