end of season sale “Shasta Daisies” are rotting

Question

I bought them in bad shape and rootbound. But once I planted them, they seemed to be doing fine. Now some of the plant’s leaves are looking black and wilted, almost like it’s rotting. HELP!

Answer 1

Most likely over watering – Are the daisies planted close together? Mine still do the same because they multiply like rabbits!
I’ve given a bunch away, and transplanted even more…each year they keep popping up!
ALWAYS remove the yellow/spotted leaves ASAP – could be mold which spreads. I cut down to about 6″ in fall, then in spring when they show signs of growth start dividing! PS – mine grow in sun and shade, and can get very tall!

Hope this helps!
