Within 7-10 days, you should see seedlings emerge.
Another method is taking cuttings from mature trees. This approach works best for experienced growers who want to preserve specific traits or cultivars. Cut a section of stem around 6-8 inches long, just above a node (where a leaf meets the stem). Remove lower leaves, leaving only two sets at the top. Dip the cutting in rooting hormone and plant it in a moistened propagation mix. Keep the soil warm and humid until roots develop.
Grafting is another advanced technique that involves joining a piece of stem from one tree onto the root system of another. This method ensures the growth of trees with desirable traits, such as disease resistance or faster maturity. When grafting collard trees, choose compatible rootstocks and prepare the cut ends before bonding them together. Maintain high humidity and ensure good air circulation to promote healing and root development.
Collard tree propagation via layering involves bending a branch down to the ground and securing it with soil or a stake. Roots will develop where the buried section meets the soil over time. This method is often used for trees that are difficult to propagate through cuttings or grafting. Regardless of which method you choose, make sure to research specific requirements for your climate and tree variety to ensure success.
