Propagation of Cotyledon Engleri
Cotyledon engleri is commonly known as the "Silver-Tip" due to the silver margins around its leaves. It is a succulent plant that belongs to the Crassulaceae family. Propagation of the plant can be done through various methods.
Leaf Propagation
Propagation of Cotyledon engleri by leaf cuttings involves taking healthy leaves from the plant for rooting. Use a sharp knife or scissors to take a leaf cutting that is 3-6 inches in length. Be sure to cut the leaf near the base as a portion of the stem is necessary for the cutting to root. Let the cutting dry for a day to form a callus before planting it in well-draining soil. The soil should be kept lightly moist, and the cutting should receive indirect sunlight. Rooting typically takes 4 to 6 weeks and can be expedited by using rooting hormone powder. New growth should be visible after two months.
Stem Cutting Propagation
Propagation of Cotyledon engleri through stem cuttings involves taking stem cuttings that are 3 to 4 inches long and free of flowers. The lower leaves of the cutting should be removed, and the remaining leaves should be cut in half. Allow the cutting to dry for a day to form a callus before planting it in well-draining soil. The soil should be kept lightly moist, and the cutting should receive indirect sunlight. New roots should sprout within 2-3 weeks, and new growth should appear after two months.
Seed Propagation
Propagating Cotyledon engleri by seed involves using fresh seeds that have not dried up. Sow the seeds in well-draining soil and water until the soil is moist. The seeds should be kept at a temperature between 18°C to 21°C until germination, which normally takes between 2-3 weeks. Keep the seedlings in indirect sunlight once they start growing leaves, and transplant them into individual containers once they reach a height of 3-4 inches.
Propagation of Cotyledon engleri by any of these methods is relatively easy, and with proper care, the rooted cuttings or seedlings will grow into healthy mature plants with beautiful silver-tipped leaves.
Disease and Pest Management for Cotyledon engleri
Cotyledon engleri is a succulent plant that usually grows without any major issues with pests or diseases. However, there are still some common issues that you should be aware of to ensure the health and longevity of your plant.

The best way to manage root rot is by removing the plant from the soil and inspecting the roots. If the roots are brown and mushy, they need to be trimmed, and the plant should be replanted in fresh, well-draining soil. It is essential to ensure that the soil is only moist and not overly wet to prevent any recurrence of the condition.
Overall, pest and disease management for Cotyledon engleri is relatively easy, as long as you take preventative measures and monitor the plant's condition regularly. If you notice any signs of pests or diseases, tackle them immediately to prevent further damage to your plant.
