How to water potted camellias (how often) how to fertilize camellias

Camellia is a very beautiful flower with bright color, elegant and dignified appearance, and has high ornamental value. Camellia is often planted at home as an ornamental plant, but those who plant potted camellias for the first time do not know how to maintain and manage them. The following editor will explain in detail the watering and fertilization skills of camellias.

How to water potted camellias (how often)

It will be watered every three hours or so. When watering camellias, the time of watering varies according to the season. In spring and autumn, it is generally possible to water except in the morning and noon. In summer, it should not be watered at noon. It should be watered in the morning and evening. In winter, watering is usually at noon when the temperature is high, do not water sooner or later, watering should pay attention to the water temperature, not too low.

How to fertilize camellias

1. Nitrogen fertilizer promotes spring shoot.

When the general temperature is about 18 ℃, camellias begin to shoot in the shade. At this time, bud-destroying fertilizer based on nitrogen fertilizer should be applied, about once every 10 days, until the spring shoot begins to Lignification. Or foliar spraying with a mixture of potassium dihydrogen phosphate, urea and rice vinegar. In this way, after many times of root and foliar spraying, the spring shoot will grow very luxuriantly, the leaf can extend to the maximum, and the shoot can accumulate rich nutrients, creating very good conditions for flowering.

2. increase the application of phosphorus and potassium fertilizer for flower bud and flower bud differentiation.

The spring shoot of camellia is full, and after Lignification, there will be a short period of semi-dormancy. At this time, the camellias will turn to the growing period, and the flower buds will begin to differentiate. If you want to make camellias produce more buds, you should apply more phosphorus and potassium fertilizer and little or no nitrogen fertilizer at this time. This can not only control the excessive growth of camellia branches, but also promote and shorten the time of flower bud differentiation, which will be more conducive to the formation of flower buds.

3. it is not suitable to apply fertilizer in midsummer.

Due to the hot weather in midsummer, camellias grow slowly, and most of them are in a state of semi-stagnation. It is not suitable to apply fertilizer at this time, especially not to apply thick fertilizer. If the soil is barren, thin liquid fertilizer can be applied in combination with watering to improve the soil quality.

4. Appropriate application of mixed fertilizer based on phosphorus and potassium fertilizer in autumn

The sky is high and cool in autumn, which is the period of nutrient accumulation of camellia plants. In order to survive the winter safely, the mixed fertilizer based on phosphorus and potassium fertilizer can be applied every half a month, or foliar spraying can promote plant health and improve the cold resistance of camellias.

5. Dilute phosphate and potassium liquid fertilizer should be applied in winter.

Camellias in cold winter enter a semi-dormant period and do not need much fertilizer. When camellias enter the house, the vegetative growth has entered a dormant state, but its reproductive growth has not stopped completely, so it should be combined with watering and applying thin phosphate and potassium liquid fertilizer. (do not apply thick fertilizer) to prepare for next season's flowering.

What should I do if there is too much fertilizer for camellias?

First of all, we should do a good job of prevention, try to be reasonable when applying fertilizer, try to use organic liquid fertilizer, the concentration of fertilizer should not be too high, and do not apply fertilizer too frequently.

The second is to change the basin and soil frequently. After the camellia has grown for a period of time, it is like a plant that has been growing for a year or two. At this time, the soil in the flowerpot is old soil and may have accumulated too much fertilizer. In addition, a phenomenon of fertilizer damage is abnormal stagnant water in the pot. So it is best to change the basin and soil frequently. When changing the pot, put the flowerpot high and try not to touch the ground.

Finally, it is found that the phenomenon of fertilizer damage to camellias, it is best to immediately change the pot, or pruning the plant, re-cutting or grafting propagation, so that camellias grow again.

What is the reason why camellias do not grow?

1. Inappropriate watering: camellias grow too slowly or stop growing in large part because they are not watered too much, and the growth of camellias will slow down when they are not watered enough; too much watering will cause rotten roots, which is not conducive to plant growth.

2. Too little fertilizer: too little fertilization will lead to insufficient nutrition of camellias and affect plant development.

3. Improper lighting: too much direct sunlight or insufficient sunshine will affect the normal growth of camellias.

4. Moving seedlings is too late: many people will transfer seedlings to camellias during the Spring Festival, which is an important reason for the poor growth of camellias.

As mentioned above, in fact, when we raise some flowers and plants in our leisure time, we can not only get in touch with pressure and relax our mood, but also cultivate our self-cultivation. Whenever dragging a tired body back home, the flowers are bright and colorful and vibrant, can it make you feel more happy?
