The reason and solution of the loss of leaves of potted tea plum how to cultivate potted tea plum

Camellia oleifera is a kind of plant that looks like tea tree and flowers like plum blossoms. It has high ornamental value. Its ornamental point mainly lies in its flowers, which are generally common in rose red. Nowadays, many people like to cultivate tea plums in potted plants at home. However, in the process of breeding, there may be fallen leaves due to technical reasons, so how should it be solved?

The reason of losing leaves of potted tea plum and its solution

First, the reasons:

1. Improper lighting. Tea plum can not stand strong sun exposure. If tea plum is placed in a place of direct sunlight during the growth of tea plum, it will affect the growth of tea plum and cause the leaves of tea plum to fall, and the strong light of summer sun will burn the leaves and buds, causing the leaves to curl, scorch and fall off. However, if tea plum is put in a dark environment for a long time, without sunlight and photosynthesis, the leaves of tea plum will also fall.

2. Watering is unreasonable. Tea plum likes yin and dampness, and the growth of semi-shade environment is the most suitable, but improper watering is also the key to the healthy growth of tea plum. Too little watering will cause the soil to be too dry, so that the branches and leaves need less water, and the leaves dry up and fall off. Excessive watering causes stagnant water, which not only affects the respiration of tea plum roots, but also affects the growth of leaves.

3. Excessive fertilization. In particular, the young seedlings of one or two-year-old tea plum have tender and weak roots and cannot be fertilized with thick fertilizer. excessive fertilizer will burn the roots of tea plum, causing leaves to fall, and in serious cases, it will also lead to plant death.

2. Solution:

1. Proper shading. As the temperature continues to rise, pots can be placed around noon on the north windowsill or balcony of the north house, accepting only the rising sun and sunset, while avoiding the direct sunlight around noon, and should be placed under the eaves of the corridor or under the scaffolding in the courtyard in summer.

2. Proper watering. After the newly transplanted or newly mailed tea plum seedlings are fully watered for the first time, do not water as long as the pot soil is not dry, spray water to the plant and the basin surface 3 times a day to keep the basin soil slightly moist, ensuring that the leaves are not short of water, and do not make the basin soil too wet.

3. Fertilization is light. In general, a dilute nitrogen fertilizer was applied from February to March to promote the growth of branches and leaves. A thin cake fertilizer and water was applied from April to May to facilitate flower bud differentiation. 0.2% potassium dihydrogen phosphate was applied from September to October to make the flowers bright.

How to cultivate potted tea plum

1. Soil: Camellia oleifera is suitable for growing in acid sandy soil with loose fertility and good drainage, alkaline soil and clay are not suitable for planting, and lime soil is more taboo to be used. when potted in the north, it is appropriate to choose rotten leaf soil or peat soil, plus a small amount of river sand culture soil.

2. Watering: tea plum should be watered to keep the basin soil moist without stagnant water. It should be watered once every morning and evening in summer and once in several days in winter. In addition to winter, should also spray water to the leaf surface every few days, in order to keep the leaf surface clean, watering must be thoroughly watered.

3. Sunshine: Camellia oleifera is a semi-shady plant, avoid strong light. Generally, it should be cultured in the shade from May to September every year. If it is directly exposed to the hot sun, it is very easy to burn leaves and buds, causing leaves to curl and scorch and fall off in serious cases. We need more sunshine in late autumn and winter.

4. Temperature: tea plum likes warm environment, and the suitable temperature for growth is 18-25 ℃. The temperature should not be too high. When the temperature exceeds 35 ℃, the tender leaves are prone to birthday burn. At the same time, Camellia oleifera has strong cold tolerance and can be kept in a cold room of more than 2 ℃ in winter.

How to prune potted tea plum

Camellia and Camellia also need to timely thinning buds and cut off residual flowers in order to reduce nutrient consumption. In general, each branch leaves 1 bud, the rest are sparse, so that nutrients are concentrated, then the flower is large and colorful. Cutting off the residual flowers in time can not only keep the plant shape beautiful, but also conducive to the germination of new branches, but also promote the healthy growth of the plant.

Common diseases of potted tea plum and their control

1. Anthrax. Guoguang Yintai (80% Dysen zinc wettable powder) 600 Mel 800 times solution and Guoguang Sitalin can be sprayed regularly to prevent and supplement nutrition before disease prevention and improve ornamental. In the early stage of the disease, 25% prochloraz EC 500 Mel 600 times or 50% mn-Zn wettable powder 400 Mel 600 times were sprayed at the initial stage. 2murine was used 3 times in a row, with an interval of 7murine for 10 days.

2. White star disease. Prevention and treatment methods: chlorothalonil and Dyson zinc are protective fungicides, which are suitable for prevention before the disease. It is recommended to use Guoguang chlorothalonil or 80% Dysen zinc 600Mel 800 times spray before the disease.

Potted tea plum leaves are generally caused by light, waste water and other aspects, if you want to solve completely, it is necessary to find out the cause from the root. At ordinary times, we also need to strengthen management in breeding, timely disease prevention and control, reasonable fertilizer and water can ensure its healthy growth.
