One of the best things about daisies, besides their delightful range of appearance and colors, is that they are usually a perennial plant. They will grow back year after year with proper pruning practices. Blooming usually in spring and summer, depending on the variety, they begin to fade in the fall. Depending on your climate there are some simple steps you can take to prune your daisies for winter.
Check what type of daisies you have in your garden to confirm they are perennials. There are a few daisies that are annuals, which means they will die off every year and need to be replaced by new daisies.
Cut back the dead stems back to soil level in late autumn/early winter when the plant has finished blooming.
Place a heavy mulch over or cover with straw in colder climates to protect them from frost and snow.
Dig up and divide your daisies every 3 to 4 years to minimize overcrowding. Signs that your daisies are getting too crowded are smaller blooms in relation to previous years.
