Morus nigra, commonly known as black mulberry, is a deciduous tree native to southwestern Asia. It is known for its dark purple to black edible fruits and has been cultivated for thousands of years. The tree can grow up to 10-15 meters tall and has a spreading habit. It prefers temperate climates and goes through a dormancy period during winter.
Black mulberry trees require moderate temperatures and thrive in full sun. They need regular watering, especially during dry periods, but the soil should be allowed to dry out partially between waterings. The tree prefers moderate humidity and should be protected from extreme cold.
收成
Morus nigra, commonly known as black mulberry, should be harvested when the fruits are fully ripe, typically in late summer to early autumn. The berries should be deep purple to black in color and should come off the tree easily with a gentle tug. It is best to harvest in the morning when the fruits are cool. Use a soft container to avoid bruising the delicate berries. Regularly check the tree for ripe fruits, as they do not all ripen at the same time. Ensure to wear gloves and protective clothing as the fruit can stain.
土壤
Morus nigra prefers well-draining loamy soil that is rich in organic matter. The soil should be kept moist but not waterlogged. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 is recommended. Fertilize the tree in early spring and again in mid-summer to support healthy growth and fruit production.
换盆
Young black mulberry trees can be repotted every 2-3 years to refresh the soil and provide more space for root growth. Repotting is best done in early spring before new growth begins. Ensure the new pot has good drainage.
传播
Black mulberry can be propagated through seeds, cuttings, or grafting. Cuttings taken in late winter or early spring tend to root well. Grafting is also a common method for propagating specific cultivars.
修剪
Pruning is essential for maintaining the shape and health of the black mulberry tree. Prune in late winter or early spring before new growth starts. Remove any dead, diseased, or crossing branches to improve air circulation and light penetration.
毒性
Morus nigra is not toxic to pets or humans. The fruits are edible and often used in jams, jellies, and desserts. However, the unripe fruits and milky sap can cause mild stomach upset if ingested in large quantities.
额外的
Black mulberry trees can be susceptible to pests such as aphids, spider mites, and scale insects. Regular monitoring and appropriate treatments can help keep these pests under control. Mulching around the base of the tree can help retain soil moisture and suppress weeds.
