Q.Forsythia plant is turning brown and leaves are curling up
The forsythia I planted last year is starting to turn brown and some of the leaves are curling up. I looked for bugs but there are none. The main plant is still green but the newer growth is turning colour.
Should I be spraying the leaves with something, or cutting off the brown sections? We have had lots of rain so lack of water is not the issue.
You may have a forsythia blight which is treatable. Always remove infected leaves quickly, prune out dead stems and don't compost the debris. In fall, remove all leaves from the vicinity. Here are 2 articles that I hope will help you pin down the problem. Make sure there are no signs of a burrowing animal that might have destroyed roots.
