Propagation of Sutera Kraussiana (Bernh.) Hiern var. Latifolia (Bernh.) Hiern
Sutera Kraussiana (Bernh.) Hiern var. Latifolia (Bernh.) Hiern is commonly known as Bush violet or trailing violet, which is a beautiful trailing plant originated from South Africa. Propagation of the plant is easy and can be done using various techniques.
Propagation by Stem Cuttings
Propagation of Sutera Kraussiana (Bernh.) Hiern var. Latifolia (Bernh.) Hiern can be done using stem cuttings. This method is considered to be the most effective way because of the high success rate. Stem cuttings should be taken from the parent plant in the spring or summer when the plant is actively growing. The cutting should be around 5 to 6 inches long, and it should have at least two pairs of leaves. Remove the leaves from the lower half of the cutting and dip the cutting into rooting hormone. Plant the cutting in a well-draining potting mix and water it thoroughly. Keep the potting mix moist until the cutting establishes roots.
Propagation by Division
Sutera Kraussiana (Bernh.) Hiern var. Latifolia (Bernh.) Hiern can also be propagated by dividing the parent plant. This method is best done in the spring or fall when the plant is not in its active growth phase. Carefully dig up the parent plant and gently separate the root ball into smaller sections. Replant the divided sections in well-draining soil, water them, and keep them moist until they establish roots.
Propagation by Seeds
Propagation of Sutera Kraussiana (Bernh.) Hiern var. Latifolia (Bernh.) Hiern can also be done using seeds. However, this method is less common because the plant doesn't produce viable seeds frequently. To propagate using seeds, collect the seeds and plant them in a well-draining potting mix. Keep the soil moist and warm, and the seeds will sprout within a few weeks.
Remember that the Sutera Kraussiana (Bernh.) Hiern var. Latifolia (Bernh.) Hiern is a delicate plant and can be easily damaged. So, it's important to handle it with care when propagating it.

- Powdery mildew: Powdery mildew can affect Sutera kraussiana (Bernh.) Hiern var. latifolia (Bernh.) Hiern, especially during humid conditions. To manage this fungal disease, use fungicide sprays or trim off and destroy severely infected plant parts.
- Crown rot: Planting Sutera kraussiana (Bernh.) Hiern var. latifolia (Bernh.) Hiern in well-drained soil is vital to control crown rot. If it is already affected by the disease, replace the soil with a healthy one, and sterilize the pot carefully with 10% bleach solution.
- Leaf spot: Leaf spot is relatively common in Sutera kraussiana (Bernh.) Hiern var. latifolia (Bernh.) Hiern and can cause small black spots on the leaves, damaging the overall presentation of the plant. To manage leaf spot, remove infected plant parts and stem cuttings that are also affected, and destroy them.
Pest Management
Sutera kraussiana (Bernh.) Hiern var. latifolia (Bernh.) Hiern is generally in low risk for pests, but they can still get infested by common plant pests like the following:
- Aphids: Aphids can suck on the sap of Sutera kraussiana (Bernh.) Hiern var. latifolia (Bernh.) Hiern leading to slow growth and weaken the plant. Use a blast of water to get rid of them or use insecticidal soap and neem oil.
- Spider mites: Spider mites thrive in hot and dry environments, suction their sap, and could cause leaves to turn yellow. Using well-draining soil and regularly misting the plant can maintain the humidity. Insecticidal soap can also help eliminate them
- Mealybugs: Mealybugs or woolly aphids are tiny white insects that suck on the plant's sap causing the plant to wilt. Insecticidal soap is an effective solution for managing mealybugs.
