Questions About Coreopsis Plants

    There are so many varieties of coreopsis, some are annual and some are perennial, and some are much more winter hardy than others. The winter could certainly have affected them in some way. At best, they last only 2 -5 years, so the weather may have hastened their old age. I think I would plant some different varieties, but leave those, in case they recover after some extra time. Here's some general information on these beautiful flowers: https://www.gardeningknowhow.com/edible/fruits/oranges/growing-an-orange-tree.htm

    We trim ours off as far back towards the main plant as possible. More blooms will come in fairly sort order too!

    I like to trim mine down to the next leaf structures.

    I use a small sharp garden scissors and it makes a nice clean cut.

    This article should help, though it's directed to roses it would still apply to your situation as well: https://www.gardeningknowhow.com/ornamental/flowers/roses/budworms-roses.htm

    If it is not budworms but another caterpillar or worm pest attacking your plant, then they can be treated with products containing Bacillus thuringiensis (Bt), a natural bacteria that kill worms without harming plants. Neem oil may be helpful as well. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/using-bacillus-thuringiensis.htm

    Coreopsis should do well being moved this fall. Prepare the temporary bed and move the plants. Water the plants well for the first 2 weeks, then you can cut back. Mulch around the plants for moisture retention and winter protection.

    Your growing zones are 10-11, making it possible for you to grow a number of plants--many of these year round. You can grow coreopsis and blanket flower together, as well as all the other plants you mentioned. As long as they all share the same or similar growing requirements, these plants can be grown together in the garden.

    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.
