Kotschya Platyphylla (Brenan) Verdc. does not require fertilization; however, adding compost to the soil before planting can enhance growth. Use slow-release fertilizers sparingly, as too much will cause the plant to produce excessive leaves rather than flowers.
Pruning Kotschya Platyphylla (Brenan) Verdc.
Kotschya Platyphylla (Brenan) Verdc. does not require pruning, but removing the spent flowers can improve the appearance of the plant. Cut the stem off just above the base of the plant to prevent rotting at the cut end. With time, the plant will produce offsets that can be divided every three to four years, and planted separately.
Propagation of Kotschya platyphylla
Kotschya platyphylla (Brenan) Verdc. can be propagated by several methods, including seed propagation, division, cuttings, and layering.
Seed propagation
K. platyphylla can be propagated by seed. Sow the seeds in a well-draining soil mix in a warm and bright location. Keep the soil lightly moist until the seeds germinate, which usually takes 2-4 weeks. Once the seedlings have developed several leaves, they can be transplanted into individual pots.
Division
K. platyphylla can also be propagated by division. Carefully dig up the plant and divide it into smaller clumps with a sharp, sterile tool. Make sure that each division has a healthy root system. Replant the divisions in a well-draining soil mix in their original location or in new areas.
Cuttings
K. platyphylla can be propagated by stem cuttings taken in the spring. Cut a stem with a few leaves and remove the lower leaves. Dip the end of the stem in rooting hormone and plant it in a well-draining soil mix. Keep the soil moist and place the cutting in a bright, warm location until roots develop.
Layering
K. platyphylla can be propagated by layering in the spring. Bury a stem in the soil and peg it down with a wire or a small stake. After a few weeks, roots will develop from the buried section of the stem. Cut the stem from the parent plant and transplant the new plant to a well-draining soil mix.

Root rot: Root rot is a fungal disease that affects the roots of Kotschya platyphylla, causing them to become soft and mushy. It is often caused by overwatering or poorly drained soil. To manage root rot, remove any infected roots and improve the drainage of the soil. You can also apply a fungicide to prevent the spread of the disease.
Common Pests
Spider mites: Spider mites are common pests that affect Kotschya platyphylla. They appear as tiny red or brown insects on the leaves of the plant, causing them to become discolored and distorted. To manage spider mites, remove any infected foliage and improve the humidity around the plant. You can also apply an insecticide to control the spread of the pest.
Aphids: Aphids are another common pest that affects Kotschya platyphylla. They appear as small, soft-bodied insects on the leaves, stems, and flowers of the plant, causing them to become distorted and stunted. To manage aphids, remove any infected foliage and improve the humidity around the plant. You can also apply an insecticide to control the spread of the pest.
Thrips: Thrips are small, winged insects that feed on the leaves and flowers of Kotschya platyphylla. They cause discoloration and distortion of the foliage, as well as damage to the flowers. To manage thrips, remove any infected foliage and improve the humidity around the plant. You can also apply an insecticide to control the spread of the pest.
