I'm stymied, (kinda)!
I've attached a link to pics of a plant I've been having problems with. It's a young plant (less than 2 years old) that I started from seed. Very healthy, started blooming early last summer.
The leaves started to wilt about 2 weeks ago. All over the plant, not just on one side. They're still green, no browning, or yellowing. It was in my greenhouse with other hibiscus that are all fine, still blooming, etc., and are starting to go dormant. All normal. This plant was next to a glass door on the North side of the greenhouse. I had cut back on watering, but had watered and fertilized it lightly, a few days before I noticed the problem.
I cut it back and brought it to a warmer location. The inside of the stems looked fine, no brown streaks or dishcharge.
Thinking it may be something in the soil, I got rid of as much of the soil as possible, looking for grubs, etc, (none). Root system seems to be just fine - healthy, strong, etc.
Put it in a different pot with fresh soil.
I've tried to figure out what it is thru my hibiscus books and on the Web and am thinking it was either overwatered or there's something in the soil.
This was the second hibiscus I've ever grown from seed, so I don't want to loose the little darlin'! I'm hoping I was just an idiot and overwatered it. If so, I've certainly never done it before, because I've never seen a hibiscus look lke this!
