Hi all. I’ve had this hibiscus for a few years and I’ve never pruned or trimmed her. I want it to be less “stick-y” looking and more full. It used to be bushier with dark, dark green leaves. I’ve read on this subreddit to trim but I’m having a hard time justifying the trim when the tips of the sticks have so many buds coming in. Any ideas? Also- how often should they be pruned?
