Q.It is mid September- do I trim my tick seed back

Zone 23320 | Anonymous added on September 17, 2020 | Answered

The green part of the tick seed has turned dark and dry with no blooms. Does these mean that I should trim them way down? If I do trim them now will they come back in the spring.

There are several things that could be happening to your plant, but you should go ahead and prune it back, removing any dead leaves. Coreopsis is a perennial and should come back in spring. Some varieties enjoy a severe pruning in late summer and will come back strongly. You may also want to treat the plant with neem oil just in case, but when water sits on the leaves of this plant, it can turn dark.
