Q: How should I prune the pyracantha that’s climbing the wall of my garage?
A: Pyracantha blooms in April or May on twigs that grew the previous year. If you prune severely now, you won’t have flowers or the bright red berries next year. The best method is to prune right after peak flowering in May, leaving as many flower clusters as possible. Pyracantha’s common name is firethorn, so wear thick gloves when working. If you only need to remove a wayward branch, you can do it now.
