Propagation of Sutera squarrosa (Pilg.) Hiern ex Range
The best time to propagate Sutera squarrosa is during the growing season when the plant is actively producing new growth. The plant can be propagated through various methods such as stem cuttings, division, and seed propagation.
Propagation by Stem Cuttings
Stem cuttings can be taken from the plant during the growing season. Choose healthy stems and cut 4-6 inches long cuttings from the tip of the stem. Strip off the bottom leaves and dip the cut end of the stem in rooting hormone and plant it in soil. Keep the soil moist and in a few weeks, roots will start to grow, and new growth will appear.
Propagation by Division
The plant can be divided during the growing season when it has formed new growth. Gently remove the plant from the container and carefully separate the roots into sections. Each section should have some roots and new growth. Plant each section in new soil and keep moist until new growth appears.
Propagation by Seeds
Sutera squarrosa can also be propagated by seeds. Collect the seeds from the plant when they have turned brown and dry. Sow the seeds in well-draining soil and keep moist. The seeds will germinate in 7-10 days. Once the seedlings have developed their second set of true leaves, transplant them into separate containers.
