The plant prefers to grow in a sunny location, but it can also tolerate partial shade. The ideal temperature for growing Aptosimum suberosum is between 18 and 25 degrees Celsius. The plant can be propagated from seeds or cuttings, with seeds being the most common method of propagation.
Watering Needs for Aptosimum suberosum F.E.Weber
Watering Aptosimum suberosum F.E.Weber is a crucial aspect of its care. The plant needs moderate watering during its growing season, which is from spring to summer. During this period, the soil should be kept moist, but not waterlogged. In the winter season, the plant requires less watering, with just enough water to keep the soil from drying out completely.
Fertilization of Aptosimum suberosum F.E.Weber
Regular fertilization is essential for the optimal growth of Aptosimum suberosum F.E.Weber. During the growing season, the plant should be fertilized every two weeks with a balanced fertilizer. In the winter season, fertilization can be reduced to once a month. Fertilizer should be applied around the base of the plant, taking care not to get any on the leaves or stems.
Pruning of Aptosimum suberosum F.E.Weber

Pruning should be done during the winter season when the plant is dormant. It is also advisable to remove any dead or damaged foliage regularly throughout the year.
Propagation of Aptosimum suberosum F.E.Weber
Aptosimum suberosum F.E.Weber, also known as the Karoo Num-Num, is a hardy shrub that is native to the Karoo region of South Africa. It produces beautiful bright flowers and has a long blooming season, which attracts pollinators such as bees and butterflies. Here are the methods for propagating this plant:
Seed Propagation
One of the easiest ways to propagate Aptosimum suberosum F.E.Weber is through seed propagation. Collect mature seeds from the plant, and plant them directly into well-draining soil with a covering of 1/8 inch of soil on top of each seed. Ensure the soil is kept moist but not waterlogged, and place in a warm and sunny area. Germination typically occurs within one to two weeks, and the seedlings can then be transplanted into individual pots or into a larger bed at least 6 inches apart.
Cuttings Propagation
Another propagation method for Aptosimum suberosum F.E.Weber is through stem cuttings. Take cuttings with a length of at least 2-3 inches, and remove the lower leaves to leave a clean stem. Dip the cuttings into rooting hormone, and plant them in well-draining soil. Keep the soil moist, and place the cuttings in a warm and bright location. After several weeks, the cuttings start to develop roots, and they can then be transplanted into individual pots or into a larger bed at least 6 inches apart.
Division Propagation
Aptosimum suberosum F.E.Weber can also be propagated through division. This is best done in the spring when the plant is actively growing. Dig up the entire plant and break up the clump into smaller sections, making sure each section has roots. Replant the smaller sections in well-draining soil, keeping the soil moist and placing the plant in a warm and sunny location. The new plants will establish themselves within a few weeks and can then be transplanted into individual pots or into a larger bed at least 6 inches apart.

Thrips: Thrips are tiny insects that feed on the plant's sap, causing stunted growth and discolored leaves. To manage thrips, prune infected leaves and spray the plant with insecticidal soap or neem oil.
Caterpillars: Caterpillars are the larvae of moths and butterflies that feed on the plant's leaves, causing significant damage. Handpick and destroy any caterpillars found on the plant or spray with Bacillus thuringiensis.
Common Diseases
Powdery Mildew: Powdery mildew is a fungal disease that appears as a powdery white coating on the leaves and stems of the plant. It can cause stunted growth and yellowing leaves. To control powdery mildew, remove infected leaves and spray the plant with fungicides like sulfur or copper-based fungicides.
Fusarium Wilt: Fusarium wilt is a fungal disease that affects the plant's roots, causing yellowing, wilting, and death. This disease is difficult to control, and hence the best way to manage it is to remove and destroy infected plants as soon as possible.
Root Rot: Root rot is a fungal disease that affects the plant's roots, causing them to rot and eventually killing the plant. To prevent root rot, ensure proper drainage of the soil, avoid overwatering the plant, and remove any infected plants from the garden to prevent the spread of the disease.
