Propagation of Crassula parvifolia E.A.Bruce
Crassula parvifolia E.A.Bruce, commonly known as the small-leaved jade plant, can be propagated through various methods such as stem and leaf cutting, division, and seed sowing. Each method has its own advantages and disadvantages, but in general, these methods are all effective ways to propagate a new plant.
Stem and Leaf Cutting
Stem and leaf cutting is a common propagation method for many succulent plants, including Crassula parvifolia. To propagate using this method, select a healthy stem or leaf and make a clean cut with a sharp knife or scissors. Make sure to cut the stem or leaf near the base, where it meets the parent plant. Allow the cuttings to dry for a few days, then plant them in fresh well-draining soil. Keep the soil slightly moist and in a bright, indirect light until new roots and leaves have formed.
Division
Division is another method of propagating Crassula parvifolia. If the plant is growing in a cluster or clump, gently remove the plant from the container and separate it into smaller sections. Make sure each section has roots attached. Plant each section in fresh soil and keep the soil slightly moist. Avoid exposing the plants to direct sunlight until new growth has formed.
Seed Sowing
Crassula parvifolia can also be propagated by seed. Collect the seeds from the plant and allow them to dry for a few days. Plant the seeds in fresh well-draining soil and cover lightly with soil. Keep the soil slightly moist and in a bright, indirect light. Seedlings will emerge in a few weeks, and once they have developed a few leaves, they can be transplanted into larger containers or outdoors.
Overall, Crassula parvifolia is a relatively easy plant to propagate. With the right conditions and care, you can quickly have a new plant from stem or leaf cuttings, division, or seed sowing.

2. Root rot: This disease is caused by overwatering or poor soil drainage. The plant's roots will start to rot, and the leaves will turn yellow and wilt. To manage this disease, you can remove the affected plant and repot it in fresh soil with proper drainage. Ensure that you water the plant moderately and let the soil dry out before watering again.
3. Leaf spot: This disease appears as brown or black spots on the leaves. It is caused by overwatering or splashing water on the leaves. To manage this disease, you can remove the affected leaves and wait for the soil to dry out before watering again. You can also apply a fungicide spray to prevent the disease from spreading.
Pests
1. Mealybugs: These pests appear as white, cotton-like masses on the leaves and stems. They suck sap from the plant and weaken it. To manage these pests, you can wipe off the mealybugs with rubbing alcohol or a cotton swab dipped in soapy water. You can also apply a pesticide spray specified for mealybugs.
