Gerbera daisy plants require regular and seasonal pruning when grown as perennials. Use disinfected hand shears, and wipe them after each cut to prevent the spread of disease when cutting or pruning. Pruning typically takes between 20 minutes and 2 hours.
- Perform regular maintenance
Remove dead flowers promptly at the base of their stems to encourage repeat blooming. Pinch off diseased or discolored stems or leaves as they appear throughout the season. Promptly remove leaves that have a powdery mildew. Water the roots your daisies in the morning only, and avoid getting the other parts of the plants wet when doing so.
- Harvest stems for arrangements and for a longer blooming season
Gather daisies by making clean cuts at each stem's base, and display them in a broad vase containing less than 1 inch of water to discourage stem rot.
- Provide the proper winter care
Cut your daisies back before the first frost, leaving 1 to 2 inches of growth. Dig up the plants, and pot them. Store the potted plants through the winter in a brightly lit, dry place with a temperature range of 45 to 60 degrees Fahrenheit. Gerbera daisies can remain outside in warmer climates if protected with 3 to 4 inches of mulch.
