Hello! I have a couple agapanthus that are turning yellow and drooping. They get sun until about 2 or 3 in the afternoon. They're fertilized probably once a month with liquid MiracleGro, and I've tried treating them with iron twice. Any ideas? Thanks!
Check soil moisture. Discontinue chemical applications unless and until you have specific information indicating these are needed.
Thanks. I have clay soil and water twice a week. I live in SoCal about 15 or 20 miles from the coast, but it's still hot and dry. I've been doing the chemical applications based on their appearance. You think I should stop, though?
I agree with Rob B. Chemical applications usually do more harm than good. It looks, too, you have your plants over watered. Agapanthus is drought and heat tolerant. Lift one of the bulbs to see if it is healthy or may be it is rotting. If it is already rotting the hope for recovery are slim.
As I've been reading more about them, it sounds like benign neglect is the way to go. So I'm pretty much just going to leave them alone except for a little watering and see what happens. Thanks, you guys, for all your advice!
Mulching with organic debris or stones is a good way to stabilize soil moisture conditions and moderate soil temperatures.
The top always seems so dry, though. I'll just stick my finger in a little, and it doesn't usually feel very moist. Maybe I just don't go deep enough.
