Rose of sharon won't bloom
Anyone know why my rose of sharon won't bloom? It is about 4 ft tall, and is loaded with buds that look like they are about to open, but they don't. This is the 2nd year it has done this. Last year I thought maybe it was still getting established, so I didn't think much of it, but now that it's doing it again this year, I think it must not be happy with something. The tree looks healthy overall. Thanks for any info.
