Q.Coral bells
I planted these coral bells about 3 yrs ago. I should have split them last fall, didn’t:). Now they have gone crazy with blooms. One of the plants has fallen over and is looking very bad. What should I do next? Thank you

You should typically wait till fall to split them, but if it looks like you're about to lose one, you might as well try to transplant it to see if the extra room will help the sickly one. Or, you could leave them in the same spot, pay special attention to the water and light situation and wait till fall to divide them. This article may give you some tips on continuing care:
