|I have older forsythia plants. They have finished flowering and I want to prune them. They are too tall and bottoms and centers are bare. How severe can I prune?

|Forsythia can take just about any amount of pruning. It flowers in the winter on the branches it develops in the summer so pruning now will ensure you have lots of new growth this summer and lots of flowers next winter. You can prune yours down by one third to one half. This will force growth at the bottom of the plant to help it fill in and will result in lots of new stems for flowering next winter. Best wishes with your forsythia.
