It does not look too bad in the picture so I would not panic; you should have seen my mopheads this am. In the day, I would expect some wilting on new LLs and with 99-100 temps. The blooms are getting old and when they do, they turn other shades of green with pink/etc.

Wilting 24/7 indicates that either the soil is dry or it is getting too much water so make sure you do not keep the soil always wet as this makes it easy to get root rot. A little wet now and then is ok (> week of wet and I would worry).

Check the condition of the leaves in the morning and not at night since they sometimes take a while to recover. My mopheads this AM looked wilted so I had to water them by hand. It is just plum too hot here in Texas so the leaves during the summer will wilt in the day, especially recently planted shrubs. Next year, it should behave better.

Investigate why the soil is wet so much... to confirm your overwatering suspicion. An ck why the soil may not be draining well.

I drip water 1.5 gallons on my LL per watering. Twice a week. Sometimes every other Sundays, I will also water by hand as drip does not do a good job on roots that are in the top 4".

Thank you for the info! This morning they looked just as bad unfortunately. I do not yet have a drip so I've been hand watering with a hose. The roots look pretty bad many many dead. Do you think I should remove all the blooms so she puts all energy in repairing roots? I'll sacrifice her beauty for a while if I can save her.

Removing blooms is what many people like to do on year one with all kinds of plants. I do not see a problem with that myself either. Make sure you give them about 1.5 gallons of water with the hand watering and not too much after that. But the only area that looks wilted is the top of the picture so you could leave the other unwilted stems with blooms.

Going to try it. Thank you so much!

Since we are talking about helping this plant in its new home, I wanted to mention that a limelight can get very large, 6 feet wide, large. If you are considering lifting it again, at all, you may want to move it further way from that lovely brick ledge.

Not sure of the site entirely, but it will grow onto and maybe even over that ledge in just a year or two.
