Portulaca is a large-flowered variety of purslane. It adds annual color to the flower garden, blooming from early summer until the first fall frost. Flowering may decline at midseason if portulaca isn't regularly deadheaded. Seed production uses up energy in the plant, so that there are no resources available for flowering. Removing the old flowers before they have a chance to form seeds, called deadheading, encourages the portulaca to continue producing its colorful and showy blossoms.
Things You'll Need
Shears
Inspect portulaca plants in the morning for spent blooms. Flowers close in late afternoon and overnight, so flowers may appear spent at these times when they are not. All active flowers are open in the morning.
Pinch off the withered blossoms. Remove the blossoms and the top ? inch of stem, so that the entire seed producing structure is removed from the plant.
Cut out any dead or damaged stems or leaves completely. Remove these at the base of the plant.
Dispose of or compost the removed flowers and leaves. Old plant matter left in the bed may provide bedding for insects or disease organisms.
Tips & Warnings
Deadhead portulaca once a week during the height of the blooming season.
Use pruning shears to deadhead instead of pinching the stems with your fingers, if you prefer.
