Can and should Lobelia be trimmed down hard to enable regrowth and reflowering?
Will my doing so enable it to rejuvenate? I do hope it is so, as I feel it would be the only hope for this deep 14" basket. It has got really rather loose and sprawling but few flowers. It has had liquid feeds every 10 days or so. Can anyone give me hope for it? (Its not only about getting good results, but about learning things too).
