So, do you know how it is propagated? The editor introduces the breeding methods and breeding precautions for Nandina domestica. I hope everyone likes it.

Propagation Methods of Nandina domestica

1. Sowing: Pick the seeds in autumn and sow them after harvest. On a good seedbed, with a furrow spacing of 33 cm and a depth of about 10 cm, sow evenly, with a sowing rate of 90-120 kg per hectare. After sowing, cover with ash and fine soil, and firm it. In the first year, the seedlings grow slowly. It is necessary to weed regularly, loosen the soil, and apply light animal manure. In the future, we should pay attention to annual planting, weeding and hoeing, and after 3 years of cultivation, we can plant them out.

2. Division: In spring and autumn, dig up the clustered plants, shake off the soil, cut them apart from the weak joints at the roots, with each division having 2 to 3 stems, and it is necessary to keep some roots, and at the same time cut back some large feathery compound leaves. The divided plants or potted plants can bloom after one or two years of cultivation.

Precautions for Cultivating Nandina domestica

Potted plants should be repotted once every year in early spring. When changing the pot, remove some old soil and old roots, apply base fertilizer, and fill in new culture soil. It is recommended to use a mixed preparation of 5 parts sand, 4 parts humus soil and 10 parts decomposed cake fertilizer. At the adult stage, 2 parts of decomposed cake fertilizer can be added.

Nandina domestica is grown in summer in a well-ventilated shady place. When watering every day, spray water on the leaves and nearby ground 1 or 2 times to increase air humidity and lower the temperature.

3. Nandina domestica likes moisture but is afraid of waterlogging. The number of waterings during growth and development should be increased or decreased with changes in the weather, and each time should not be excessive. Usually, water once a day in spring and autumn, and twice a day in summer, keeping the soil moist. When flowering, the watering time and amount should remain stable to prevent sudden changes, alternating dry and wet, otherwise it is easy to cause flower and fruit drop. In winter, the plant is in a semi-dormant state, and watering should be controlled. If there is too much water, it is easy to grow excessively, which will hinder dormancy and affect flowering and fruiting in the coming year.

4. Nandina domestica likes fertilizer. From May to September, apply thin pizza fertilizer water every 15 to 20 days, and about 0.2% ferrous sulfate water every two months. At the seedling stage, the liquid fertilizer should be light rather than thick (according to 1:10 liquid fertilizer and water), and at the adult stage it can be slightly thicker (according to 1:8 liquid fertilizer and water). In the rainy season, change to dry fertilizer, once a month, about 20 to 40 grams per pot.

5. Potted Nandina domestica is moved indoors in mid-October, placed in the room, and can be placed in direct sunlight in the morning and evening. The room temperature must not let it freeze. Spray the leaves with warm water once a week to keep the leaves fresh.

6. Nandina domestica should be pruned and shaped in combination with repotting, removing branches and thin twigs from the base to promote the sprouting of new branches. Usually, keep 4 to 5 branches.

Growth Habits of Nandina domestica

Nandina domestica prefers a warm and humid environment, is relatively shade-tolerant, cold-tolerant, and easy to maintain. The soil for cultivation needs to be fertile, well-drained sandy loam. Its requirements for water are not very strict; it is both moisture-tolerant and drought-tolerant. It needs more fertilizer, especially phosphorus and potassium fertilizer. Apply liquid fertilizer 1 to 2 times a month during the growth period. After several years of potted cultivation, the branches and leaves age and fall off, and the whole shape can be pruned. Usually, the main stem can be kept at about 15 cm. After pruning in autumn, it can recover to a mysterious height, and the crown is full.
