Watering Needs for Sutera densifolia Hiern
Sutera densifolia Hiern requires moderate watering, and it is important to keep the soil moist, but not overly wet. It would be best to water the plant once the top inch of soil has dried. The plant also requires watering frequently during its active growing season, which is from spring to fall. During the winter season, reduce watering to prevent overwatering and root rot.
Fertilization for Sutera densifolia Hiern
Sutera densifolia Hiern thrives in well-fertilized soils. During its active growing season, you can feed it with a balanced fertilizer, such as a 10-10-10 formula, every two weeks. Fertilizers will help produce more blooms and enhance the color intensity of the flowers.

Propagation of Sutera densifolia Hiern
Sutera densifolia Hiern can be propagated through various methods, including seed propagation, stem cuttings, and division of the clumps.
Seed Propagation
The easiest way to propagate Sutera densifolia Hiern is through seed propagation. The seeds should be sown in a well-draining potting mix in early spring. The seeds should be covered with a thin layer of soil and kept moist but not waterlogged. The germination process takes about 4-6 weeks, and the seedlings should be thinned out to avoid overcrowding.
Stem Cuttings
Sutera densifolia Hiern can also be propagated through stem cuttings. The stem cuttings should be taken from the plant during the early summer months. The cutting should be about 7-10 cm long, and the lower leaves should be removed. The cutting should be planted in a well-draining soil mixture and kept moist. It takes about 4-6 weeks for the cuttings to root, and the plant should be transplanted to a bigger pot when it starts to outgrow the existing pot.
Division of the Clumps
Sutera densifolia Hiern can be propagated through the division of the clumps. This method should only be used for mature plants that have outgrown their container. The plant should be carefully lifted from the container, and the clumps should be divided into smaller sections. Each section should have at least two leaves and a portion of the root system attached to it. The divided sections should be planted in a well-draining soil mixture and kept moist until they establish themselves.
Overall, Sutera densifolia Hierns are relatively easy to propagate, and each method has its own advantages and disadvantages. By choosing the appropriate method, one can increase the number of Sutera densifolia Hierns in their garden or home.
