Portulaca, also known as moss rose, can be propagated by taking cuttings or sowing seeds.
Cuttings
Take a cutting: Using clean, sharp shears or pruners, cut a section of the plant that is a few inches long.
Remove leaves and blooms: Remove any spent blooms or buds, and the leaves from the bottom half of the stem.
Dip in rooting hormone: Dip the cut end of the stem into rooting hormone.
Plant the cutting: Place the cutting in a pot or garden bed filled with moist, well-draining soil.
Water: Water enough to keep the soil moist but not soggy.
Wait for roots: Roots should appear within a few weeks.
Water regularly: Once new growth appears, water regularly.
Seeds
Collect seeds: Collect seeds from the pods that form where the flower buds were.
Sow the seeds: Follow the steps for sowing seeds.
Portulaca is easy to propagate and can be done during the summer when the plant is being pruned.
