Fertilization method of tea plum bonsai

There are many varieties of tea plum, mostly white flowers, a few safflower, mainly produced in Jiangsu, Zhejiang, Fujian, Guangdong and other provinces along the Yangtze River and in the south, suitable for subtropical trees. For the new pot of tea plum, there are many places to pay attention to. Special attention should be paid to fertilization, and fertilization should be done properly. For those of you who have questions about this, this article will give you a detailed answer.

1. Time for applying liquid fertilizer

Pouring liquid fertilizer is generally carried out in the evening when the temperature drops and the soil is dry. The next morning,"return water", that is, regardless of whether the soil is dry or not, water should be poured once to dilute the fertilizer solution in the soil layer to facilitate root absorption.

2. The concentration of liquid fertilizer

The concentration of liquid fertilizer depends on the length of fertilization interval, variety, seasonal alternation and plant growth. During the growth period of tea plum, it should be applied once every week or 10 days. If the fertilization interval is long, it can be applied with medium concentration of fertilizer water mixed with 10 times water. Fertilization interval is short, should reduce the concentration, with 15 times or 20 times water application. Tea plum, strong growth of varieties, fertilizer appropriate concentration. Young plants, weak plants, rare varieties, light. The first fertilization in spring should be light, and then gradually thickened. Plum rainy season soil wet, or ponding, unfavorable fertilization. Potted plants can be sprayed with fertilizer on the leaves. Growth season, fertilization can be appropriately thickened, late autumn, winter and then gradually reduce or stop application.

3. Remedial measures for excessive or insufficient fertilization

1. The leaves are dark green, the leaves are large and soft, the mesophyll color becomes pale, the flowers are few, and the legs are long, which is the symptom of excessive fertilization. Light will affect growth, development, branching, flowering, heavy will affect normal growth, causing more diseases and insect pests. At this time must stop fertilization, planting, take irrigation, drainage methods to dilute fertilizer concentration. potted plants, take soil replacement or soak;

2, such as slow growth, small and thin leaves, yellow leaves, thin leaves, which is a symptom of insufficient fertilization. The frequency and concentration of fertilization should be appropriately increased, but it should not be applied too thick and frequently.

4. In several cases, camellia should not be fertilized:

Generally speaking, flower bud color flowering period, avoid fertilization, otherwise it will cause flower drop bud.

Summer high temperature, winter semi-dormant period should not be fertilized, so as not to cause rotten roots. Branches excessive length, dark green leaves or leaves droop for a long time, which indicates excessive fertilizer or mold roots, to immediately stop fertilization.

Newly transplanted or diseased tea plum should not be fertilized. Thin fertilizer should be applied after the new plant recovers its growth function and the diseased plant is cured. For tea plum planted in autumn, no fertilizer should be applied in that year.

Generally, the tea plum in the new pot should not be fertilized. After the plant returns to normal growth, a small amount of light topdressing can be applied, and excessive concentration should not be avoided. Tea plum to use mixed organic fertilizer (human manure, manure) for good, mainly to phosphate fertilizer, nitrogen fertilizer for the secondary. If nitrogen fertilizer is too much, it will cause excessive growth of branches and fewer flowers. Can also be rapeseed cake and fish meal directly scattered in the soil surface, let it slowly rot, infiltration of the soil, for root absorption. Also may wish to apply a small amount of calcium superphosphate and other chemical fertilizers, but must be thin fertilizer less application, differential treatment: plant strong slightly more application, weak less application, sick people do not apply.

Fertilization of tea plum requires light fertilizer and full decomposition. Generally, thin nitrogen fertilizer is applied once a year from February to December to promote the growth of tea plum branches and leaves. Apply thin cake fertilizer water once between April and May to promote flower bud differentiation of tea plum. 9-10 Applying 0.2% potassium dihydrogen phosphate once a month can make the flowers of tea plum bigger and brighter.
