Can I cut back coreopsis in the spring?
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!
What do you do with coreopsis in the fall?
Laying compost or manure in the fall will allow it to break down during the winter. Mulch, if desired. The coreopsis plant should be left alone. If using fresh manure, keep it away from the roots of the plants because the high nitrogen content of non-composted manure might cause the plants to burn and die.
