Gerbera daisies sport large, colorful blooms with bright centers. Bright pink, purple and yellow are just some of the color varieties available. Grown as a perennial outdoors in the southern United States or as a potted or bedding annual in the north, prolonging the blooms of the Gerbera daisy adds color indoors or out for much longer than just letting them go to seed. Once a plant produces seeds, it stops flowering. Arresting seed development encourages further blooming.
Inspect the flower during blooming for spent flower heads. Look for browning and withering of the petals.
Cut off the stem supporting the spent bloom near the base of the plant, using sharp and clean scissors. Avoid cutting into the leaves emerging in the area.
Check the plant for seed heads forming where blooms have already withered away. These form on the top of the stem once the petals fall off. Snip the stems with seed heads off at the base.
Remove all petals that have fallen into the pot or onto the garden bed to clean up the appearance and prevent fungal diseases from breeding in them.
Continue checking and removing spent flower heads until all blooming has stopped. Cut off the last of the stems but allow the foliage to die back naturally if you are growing Gerbera as perennials. Dig up and dispose of the plant if growing as an annual.
