I'm wondering why my crape myrtle never blooms. It hadn't bloomed in years so I decided to trim in 2 winters ago. The next spring it bloomed like crazy. I didn't trim it this past winter because I shouldn't need to to get it to bloom, so this spring it did nothing and got no blooms. Do I just need to trim each year? It gets plenty of water and full sun. I feed the grass around it with nitrogen. I recall putting fertilizer spikes in one or two years before and dont recall it doing much. Maybe it is getting too much nitrogen and not enough phosphorous?
