Periwinkles and rain

How do your periwinkles take overwatering? The week of rain here in August ended and I thought that my large group of 2-yr old periwinkle volunteers had been hit by a microscopic pestilence. Branches were suddenly dead (soft stems and black leaves). I cut away all of that, and some leaves still suddenly die, but the group has survived well. They grow in dappled oak shade, drain well, and have never needed watering. Everything else in my yard of varied plants in pots and ground seemed to thrive on that week of rain, even succulents.

I know they don't do well with a lot of water, but another thing might be nematodes. I've lost them several times when planted in the ground but when they are in pots they do fine, then I read somewhere that they are very susceptible to nematodes which makes sense. So I stopped planting them in the ground.

They don't like wet feet. It kills them every time. I grow mine in the ground and they do fine, but I cut them back and put them in pots in the winter to bring inside. They don't like a lot of mulch around them, either. Honestly, if you have a place with plain old Florida sand that hardly ever gets watered, that's where they do the best.
