The name daisy encompasses many types of flowers, including the true daisy family (Bellis spp.) and a variety of plants that produce daisylike flowers, such as the Shasta daisy (Chrysanthemum maximum). Varieties are available that thrive in most climates. Fortunately, both true and common daisies respond well to similar trimming tactics, whether they are perennial or annual. Trimming the old flowers keeps the plants attractive, encourages further bud formation and can prevent the plants from unwanted self-seeding. Most varieties don't require heavy trimming, only the occasional light deadheading.
Cut back the spent flower stems after the petals droop, using sharp shears. Make each cut low on the stem, where it thickens or emerges from foliage beneath, but above any new buds forming on the same stem.
Trim back the dead flowers at least once weekly during the blossoming season. Frequent flower removal prevents seed production, which can lead to unwanted plants or poor flowering on existing plants.
Cut back the perennial daisy varieties after flowering, which can be in early summer or in fall, depending on the specific type. Remove up to a third of the foliage if it's still green to clean up the garden bed. Cut off the foliage near the soil surface if it has died back naturally for the winter.
Things You Will Need
- Remove dead or damaged foliage or stems anytime to improve the plant's appearance and prevent the spread of diseases or pests.
- Some true daisies are considered invasive, such as the common white English daisy (Bellis perennis). Hybrid varieties of B. perennis, such as "Bellisima" and "Habenero Mix," typically aren't invasive. Your county extension office can verify which varieties are safe to grow in your area.
