Problems with a Blueberry plant
I have a blueberry bush, and its around 2 months old I think, I have it in a big pot in my balcony and there are these small insects that live in the pot too, there are many of them. I bought an insecticide and use it every week to kill them but they keep coming back, they are very small, black and have wings, how do I get rid of them?
Also, my plant is developing these brown markings on the leaves and some of the leaves have curled up and fallen off the plant, I included a picture of some of the leaves. Please help.
