Fertilization for Morus microphylla Buckl.
For optimal growth and fruit production, Morus microphylla Buckl. requires regular fertilization. This can be done by applying a balanced fertilizer with a ratio of 10-10-10 twice a year during the growing season. The first application should be made in the spring, while the second application should be done in the summer.
Alternatively, organic fertilizers such as compost and well-rotted manure can be applied in the same manner to provide the plant with the necessary nutrients required for growth and fruit production.
Pruning Morus microphylla Buckl.
Pruning is an essential aspect of maintaining a healthy and productive Morus microphylla Buckl. plant. The plant should be pruned during the winter months when it is dormant. The aim of pruning is to remove diseased, weak, or damaged branches and to shape the plant to the desired form.
During the first year of growth, no pruning is necessary. In the second year, the plant should be pruned back to a height of 30cm above the ground. This encourages the plant to develop a strong structure and be in a position to produce good quality fruits. Thereafter, the plant should be pruned annually to remove any dead or diseased wood and to shape it into a desired form.
Propagation of Morus microphylla Buckl.
Morus microphylla Buckl., commonly known as the littleleaf mulberry, is a deciduous, small tree that is native to North America. The plant is often used for restoration projects, landscaping, and erosion control.
Seed Propagation
Propagation of Morus microphylla Buckl. can be done through seeds. The seeds should be collected from mature fruits that have turned dark brown. The collected seeds should be cleaned and sown in a well-drained potting mix. The potting mix should be kept moist but not waterlogged. The germination period of the seeds is typically 1-2 months. The young seedlings can be transplanted into individual pots when they have produced two to three sets of leaves.
Cuttings Propagation
Propagation through cuttings is also a viable option. Hardwood cuttings should be taken from the parent plant in the winter season. The cuttings should be approximately 6 inches long and have at least three nodes. The cuttings should be dipped in rooting hormone and planted in a well-drained potting mix. The potting mix should be kept moist but not waterlogged. The cuttings should be kept in a shaded area and the rooting period is typically 2-3 months. Once rooted, the young plants can be transplanted into individual pots.
Grafting Propagation
Grafting is another option for propagating Morus microphylla Buckl. The grafting method is typically used for creating specific varieties of the plant.
