What happened to the camellias dropping their buds? What shall I do?

Camellia is cherished by the horticultural circles all over the world because of its beautiful plant shape, bright green leaves and colorful flowers. There are many varieties of camellias, which are Chinese traditional ornamental flowers and potted plants that are often planted at home, but many people will find that camellias have lost buds in the process of planting, so how is it that camellias lose buds? What shall I do?

First, the reasons why camellias lose buds.

1. Shulei

If there is no improper maintenance of camellia, the reason for the bud of camellia is to sparse buds, some people think that too many buds is good, in fact, too many buds are bound to disperse nutrients, resulting in buds falling off due to lack of nutrition.

two。 Soil discomfort

Soil discomfort is also one of the reasons for camellia budding. Sandy soil with pH value of 5-6.5 is more suitable for camellia growth. Excessive acid or alkali, clayey soil, saline-alkali soil and calcareous soil will make camellia grow poorly, and some trace elements can not be absorbed. The lack of phosphorus, iron, sulfur and other nutrient elements in the soil will also form the phenomenon of green deficiency and bud drop.

3. Improper watering

Camellia like to be moist, avoid stagnant water, the root soil is too wet for a long time, it will suffocate the roots, light buds will fall, heavy will die. In order to protect the bud, it is necessary to keep the basin soil moist and slightly dry. If it is too dry, the fleshy fibrous root will be dehydrated and withered; if it is too wet, the fibrous root will die of suffocation and decay. When there is no water supply, the plant will drop its buds first and then its leaves.

4. The temperature is bad

Poor temperature is another reason for bud drop of camellia. It is suitable to keep 3 ℃ ~ 5 ℃ during overwintering. If it exceeds 16 ℃, it will sprout ahead of time and cause deciduous buds. Below 0 ℃, the buds will freeze. The temperature in the early stage of flowering is not lower than 5 ℃ ~ 7 ℃, and the temperature in the period of flowering is 10 ℃ ~ 15 ℃. The highest temperature is 20 ℃. If the temperature is more than 2 ℃ in winter, the buds can be preserved. Camellia most avoid the temperature difference is too large, sometimes high temperature, sometimes low temperature, the buds will all fall off.

5. Poor ventilation

Camellia bud drop is sometimes caused by poor ventilation, especially in winter, long-term indoor, poor ventilation, dirty air or room temperature more than 20 ℃, will also cause buds and leaves.

6. Winter fertilization

Camellia will enter the dormant period in winter, in the dormant period is not suitable for fertilization, even if the application of thin fertilizer is also easy to drop buds.

7. Pest infection

The diseases of Camellia include anthracnose, coal pollution, gray spot and so on, among which anthracnose is the most serious. The pests are mainly scale insects. When it is found that diseases and insect pests should be sprayed and controlled in time, otherwise serious bud drop will occur.

Second, the solution to the loss of camellia buds.

1. Caused by untimely thinning of buds.

Around August, camellia buds should be thinned in time when they are the size of soybeans, and only one well-developed bud is retained in a branch, especially on weaker plants.

two。 Caused by soil discomfort

Camellia buds caused by soil discomfort should be sprayed with 0.2% ferrous sulfate solution every week.

3. Caused by improper watering

If the basin soil has been too dry, you should first water a small amount of water, so that the basin soil is gradually moist, and then pour through the water, otherwise the root tip will lose water, the big water will not be able to adapt, and you must drop buds. It is not watered until it is about 70% dry in winter, and warm water is needed at noon on a sunny day.

4. Caused by poor temperature

When the air temperature is close to 0 ℃, move the camellias to the indoor light, cover the curtain at night to keep warm, and pay attention to adjust the temperature of the flower room to give the camellia the most suitable growth temperature.

5. Caused by poor ventilation

In order to maintain the most suitable growth temperature of camellia, we should also pay attention to ventilation and ventilation, which can be put in the window to blow properly.

6. Caused by fertilization in winter

From early spring to before flowering, camellia can be applied with mixed liquid fertilizer of nitrogen and phosphorus once or twice to prevent bud falling, but nitrogen fertilizer should not be too much. If you should store enough nutrients for flowering in autumn, you can blossom with colorful flowers. From September to October, thin fertilizers with high phosphorus content, such as rotten chicken manure, were applied every month to achieve the purpose of strengthening buds. Stop fertilizing in November and do not apply fertilizer during the winter dormant period.

7. Caused by the infection of insect pests

Anthrax damage can be sprayed with equal volume Bordeaux solution or 1000 carbendazim wettable powder, and shell pests can be sprayed or washed clean with 1000 times omethoate EC.

These are the reasons and solutions for the loss of camellia buds. Friends who have camellias at home might as well give it a try. The best way is to do a good job of prevention, so that camellias will bloom in full bloom!
