Q.My Camellia Hasn’t Grown? It Looks Unhealthy.
It gets morning sun from until about 1 or 2 in the afternoon. I use a drip system and usually let it run for 2 hours, once or twice a week. In the summer it runs probably every other day. Maybe it’s to much water? I can’t seem to diagnose it properly.
