hello. . . I have a nice sized hibiscus that I bought from the local farmers market a few years ago. it gets really tall (6+') and blooms nicely. I would prefer it to be more bushy than upright. I was told or read somewhere that if you want them more bushy then you should trim them. When is a good time to trim them? They are very slow to break dormancy here, usually mid to late June and blooming by the first part of August. . . Thanks for any help. . .
