The best time to fertilize is during the rainy season when the plant is already established and actively growing. However, it is important not to over-fertilize as this can lead to an imbalance in the nutrient levels.
Pruning for Gymnosporia Senegalensis (Lam.) Loes. var. spinosa Engl. ex Loes.
Pruning should be done during the dormant season, which is usually in late winter or early spring. This will allow the plant to grow back when the weather warms up, and new growth appears. Pruning can be done to remove any dead or diseased branches, or to control the size and shape of the plant.
It is important to use clean, sharp tools when pruning to minimize any damage to the plant. After pruning, it is advisable to apply a fungicide to prevent any fungal infections.
Propagation of Gymnosporia senegalensis (Lam.) Loes. var. spinosa Engl. ex Loes.
Gymnosporia senegalensis (Lam.) Loes. var. spinosa Engl. ex Loes. can be propagated through various methods which include:
1. Seed Propagation
Seeds can be collected from the plant and sown in seed trays filled with sandy soil. The seeds should be covered with a light layer of soil and kept sufficiently moist until they germinate. Germination should occur within 2-4 weeks.
2. Stem Cuttings
Gymnosporia senegalensis (Lam.) Loes. var. spinosa Engl. ex Loes. can be propagated through stem cuttings taken from mature wood. The cuttings should be taken during the dormant season and should be at least 20 cm long. Dip the cut end of the stem in rooting hormone and plant the cutting in sandy soil. The cutting should be kept moist and covered for a few weeks until it begins to root.
3. Layering
Gymnosporia senegalensis (Lam.) Loes. var. spinosa Engl. ex Loes. can also be propagated through layering. Choose a low hanging branch and bend it towards the ground. Make a small wound in the branch where it touches the ground and cover it with soil. Keep the soil moist and wait for roots to develop. Once the roots have developed, the new plant can be separated from the parent plant and transplanted to a new location.
4. Division
The mature Gymnosporia senegalensis (Lam.) Loes. var. spinosa Engl. ex Loes. plants can be divided into smaller sections during the dormant season. Each section should have at least one healthy shoot and a good root system. Divide the plants with a sharp knife and replant them in suitable pots or directly in the ground.
