I bought a bougainvillea last summer, I kept it inside all winter and all the leaves fell off, i figured it was the winter shock. I've had one or two leaves grow and fall off. Now that spring is here I loosened the soil in the plants pot and noticed a bunch of tiny little worms, they are very thin like 0.77mm pencil lead and an inch or smaller in length. I rinsed a few off with water and noticed that they were opaque and with dirt inside of them? I live on a third floor so the plant has been kept on a balcony above ground level. Any ideas of where these worms came from and if they are harmful to my plant, if so how do i get rid of them?
Thanks for all your help.
