The reason and solution of Camellia not blooming

Due to the large color and variety of camellia, it can be said that camellia is the heart of many flower friends. However, some flower friends often encounter the situation that camellia flowers do not bloom in the process of cultivating camellias. The editor will analyze the more common reasons and solutions for you.

Camellia (details)

First, do not turn the basin for a long time. Camellia has not grown for several years, and growing smaller and smaller, this is a common problem encountered by many flower growers, one of the very important reasons is that they do not turn the pot for a long time. The root system of camellia is good breathable and likes new soil and mud, so it is necessary to turn the pot to change the soil and cut off the aging roots in time, so as to promote the growth of new roots and make the camellias grow vigorously. After the camellias blossom in spring, family cultivation should be changed at least every other year, of course, it is best to change once every six months, after the new shoots are fully ripe. The specific measures are as follows: take out the camellias together with the basin soil, cut off the basin soil with a sharp knife, cut off the aged roots, put them back into the basin, fill the gaps with pond mud or other new soil mud, and wet the soil with water to make the soil moist. Just get in touch with the roots.

Second, lack of humidity. Camellia likes a humid and cool environment, dry air, high temperature and high heat will lead to its water imbalance and die. Therefore, cultivation on the balcony is often difficult to raise because of poor air mobility, dry environment and high temperature when direct sunlight. In order to solve this problem, it should be placed in the sun in winter, and often spray water to the leaves to make the leaves breathable. In summer, the tile pot for growing camellias is placed in a layer of water 3 cm to 5 cm thick, so that it is possible to produce gorgeous flowers.

Third, keep it indoors for a long time. When the camellias are in full bloom, it is OK to put them indoors for a long time, but putting them indoors for a long time will cause thin branches and leaves, thin leaves, can not withstand strong light exposure, and is prone to sunburn. Therefore, camellias had better be planted on the balcony, but shading should be done in summer. When the temperature drops below 0 ℃ in winter, you can move indoors, but keep away from the heat source. When the weather is fine, open windows to breathe during the day.

Fourth, there is too much fertilizer and water. Camellia is not tolerant to fertilizer, fertilizing too often, there will be prosperous growth, but do not bear buds. Therefore, fertilization should be controlled as far as possible in summer to prevent burning the root system. If fertilization is really needed, we should grasp the principle of "light rather than thick, less than more, less watering many times". The time of fertilization is better on cloudy days or after 5 o'clock in the afternoon. Some breeders like to use urea as topdressing, which is very disadvantageous to the growth of camellias, especially for young camellias, topdressing urea will cause leaf loss, especially excessive concentration, which will cause reverse osmosis and cause plant death. The period from late July to August is the high temperature dormancy period of camellias, and no fertilizer can be applied at this time. Camellia needs more water in the whole process of growth and development, but watering should be based on the principle that the pot soil is dry and wet. If 0.1% ferrous sulfate is added to the water, the plant growth can be promoted and the leaf color is dark green.

Three main reasons for the non-flowering of Camellia and their Solutions

Three main reasons for the non-flowering of Camellia and their Solutions

Today, the editor of the Flower Bonsai Network shares an article about the three major reasons why camellias do not blossom and their solutions. Let's take a look.

Camellia

YANGHUADAQUAN

Reason 1: temperature discomfort

The suitable temperature for camellia bud stage is 10-15 ℃. The cold air is active in winter and early spring, and the temperature often drops below 5 ℃, which can cause frostbite in buds and do not blossom. Therefore, the flowers should be placed in a warm place without wind and sun during the day and moved indoors at night; if the temperature is below 5 ℃, cover the flowerpot with a plastic bag to increase the temperature.

Reason 2: insufficient humidity

After 10:00 on a sunny day in winter and spring, spray or spray the camellias to keep the air humid. Generally, water is watered every 3-5 days on sunny days to keep the basin moist, not too dry or too wet. Large pots can be watered every 5-7 days. When planting camellias on the ground, you should flexibly master spraying or watering according to the situation.

Reason 3: excessive fertilization

Overfertilizing causes the camellias to grow abruptly three times a year. So that it has no chance of budding and blooming. There are only long leaves but no blossoms.

What to do with Camellia buds? causes and Solutions of Thunder falling from Camellia

In the cultivation of any flowers, there will be problems, the cultivation of camellia is no exception, camellia bud how to do? Next, let's share with you the causes and solutions of the thunder fall of camellia.

Reasons for bud drop of camellia: 1. Thinning buds

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.

Solution: 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.

Reasons for bud drop of camellia: 2. 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 nutrients in the soil will also form the phenomenon of green deficiency and bud drop.

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

Reasons for bud drop of camellia: 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.

Solution: 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 water thoroughly, 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.

Reasons for bud drop of camellia: 4. The temperature is not good.

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.

Solution: when the air temperature is close to 0 ℃, move the camellias to the indoor light place, 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.

Reasons for bud drop of camellia: 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.

Solution: when maintaining 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.

Reasons for bud drop of camellia: 6. Fertilization in winter

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.

Solution: from early spring to before flowering, mixed liquid fertilizer of nitrogen and phosphorus can be applied 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.

Reasons for bud drop of camellia: 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.

Solution: 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.
