Hi again. Using the same thread as it's still relevant to my issue...

I am back and glad to say my dahlias made it past the pests thanks to the advice and began blooming a couple weeks ago. I had tons of beautiful blooms.

My issue:

We had 3 days of VERY bad rain/flooding. Our yard is under the water table and we had sitting water for about 3 days. The dahlias are raised a bit so they were not submerged, but the area where the dahlias were in the yard is around where the water retreated to last, so it was near the sitting water the longest. The first day of sitting water I only had one plant drooping. On the third day they all have begun to droop but one. They are not looking too good, and we just had rain again this morning.

My question:

Anyone have this issue with too much water/rain? Do I wait it out? Do they bounce back? Do they rot easily? If so should I dig them up early to dry before they rot?
