I will need to prune back a burning bush to reduce its size. It is currently about six feet and I am hoping to reduce it to about 3 feet. I know that this can be done. I am wondering about timing. I am not sure if late Fall or early Spring is better. I also have some Privets that I plan to thin out. A Magnolia also. Pruning will all be selective thining by hand. I am aware that the Magnolia buds have already been set for the coming season. Pruning is enjoyed, have been told that I excell at it. Embarassed that I lack this knowledge of timing. Guess this is how we learn. In advance, thank you for your help!
