A: Marguerite daisies are considered as annuals in other gardening regions, but as you’ve discovered, they become woody perennials in southern California! To keep the plants in shape, pinch and prune them while they’re still young. Because your plants are overgrown, it may take an entire growing season to gradually diminish their size without causing undue stress. Remove roughly one-third of the length of the stems in early spring, just before new growth begins. New growth will be forced from below the incisions. During the growing season, remove any wasted blooms as well as some stems. This will foster bushy growth while also keeping the plant’s height and width under control. In a same way, you can shrink the size of your coreopsis. Cut back the stems once the blooms have faded to keep the plants looking lovely, and fresh flowering stems will grow lower down on the plant. Take advantage of your new surroundings!
When should I cut back my coreopsis?
After the summer growth season, trim back Coreopsis cultivated as a perennial. Reduce the plant’s height by one-third to one-half. According to the University of California Cooperative Extension, pruning should not reach into the older brown woody growth, as this could destroy the plant.
How do you prune coreopsis for winter?
Many perennials benefit from being pruned down for the winter months so that they can come back with vigor the following spring.
Cutting them back at all, though, might be fatal for this short-lived perennial. The stems and foliage on the plant benefit from being left intact since they act as insulation and help shield the crown from the cold.
So, regardless of your growth zone, after the plant has died all the way back, you should ideally leave the stems and foliage in situ. In the fall, the leaf changes color to a lovely mahogany before drying to a brownish-gray tint, giving dimension to your landscape.

Late in the summer, cut “Early Sunrise” back to just a few inches above the ground to encourage the growth of new, compact leaves. In the fall or early spring, consider relocating the plant to a drier location with less rich soil.
