You can trim back the long stems to create a bushy, compact plant. This can be done in late spring or early summer, just before the plant blooms.
Also, deadhead spent flowers to encourage new growth and to prolong the blooming period.
Propagation of Mesembryanthemum thunbergii Haw.
Mesembryanthemum thunbergii Haw., commonly known as ice plant or rock rose, is a succulent plant of the family Aizoaceae that is native to South Africa and Namibia. The plant has attractive, daisy-like flowers that bloom in shades of pink, magenta, white, and yellow. It is commonly grown in rock gardens, containers, and as a groundcover plant.
Propagation by Seeds
The most common method of propagating Mesembryanthemum thunbergii Haw. is by seeds. It is best to sow seeds in the spring or early summer, in a well-draining soil mix that is rich in organic matter. The seeds should be sown thinly and covered with a light layer of soil. Water the soil well and keep it consistently moist until the seeds germinate, which usually takes 2-3 weeks. Thin the seedlings to a spacing of 4-6 inches apart.
Propagation by Cuttings
Mesembryanthemum thunbergii Haw. can also be propagated by stem cuttings. Select healthy stems that are 2-3 inches long and remove the leaves from the bottom half of the stem. Dip the cut end of the stem in rooting hormone and plant it in a well-draining soil mix. Water the soil well and keep it consistently moist until the cutting roots, which usually takes 4-6 weeks. Once the cutting has rooted, it can be transplanted into its permanent location.
Propagation by Division
Another method of propagating Mesembryanthemum thunbergii Haw. is by division. This is best done in the springtime when new growth begins to emerge. Carefully remove the plant from its container or ground location and separate the clumps with a clean, sharp knife. Each clump should have its own roots and stem system. Replant the clumps in their permanent location and water them well.
