We've had this rhododendron for a few years now and it has never really grown up. It flowers a few times in the summer, but continues it looks really sad and pathetic. It's in full sun in the morning and then mostly shade after noon.
I'm (very) new at gardening so am reading up on the plant and am not sure what advice to follow. I know that the soil PH is 6.25, which may be the issue?? I've read mixing vinegar w water will help the soil be more acidic, but I don't want to make things worse.
Any ideas?
