What do you do with the Tickseed Coreopsis flower before winter sets in? I have just planted the Tickseed Coreopsis flowers and I want to know what to do with the plants before winter. Should I cut them back to ground level or just let them alone?
According to my research cutting down tick seed coreopsis may decrease their chance of winter survival and risk the plant putting on new growth using energy reserves intended for spring. So, I would recommend leaving them alone.
