Overwatering serbian bellflower
I had a very healthy vital Serbian bellflower planted in full sun and it was doing great. However, within the last 2 weeks, it started looking like someone had stepped on the middle of it (they hadn't). Tonight I moved some of the plant stems and the whole thing separated from its base plant. The plant 1.5 feet away from it is doing beautifully with no issues. Could this be the result of overwatering or a pest of some kind? Thank you!

Serbian Bellflower is susceptible to crown rot and mildew under wet conditions.
The top 2 inches of soil should dry out between watering.
Avoid having mulch up to the plant, give it room to help dry out the soil.
