Camellia safely through the rainy season requires five prevention, water control, fertilizer, pruning and disease prevention.

In the rainy season from April to August every year, if the potted camellias are slightly careless in management and maintenance, the branches and leaves may cause wilting, leaf yellowing, shedding, or physiological damage and affect the normal growth of the plant throughout the year, or even cause the whole plant to die. In order to make potted camellias safely through the rainy season, "five precautions" must be achieved.

1. Prevention of stagnant water in the basin

When potted camellias are put outdoors, it is easy to cause stagnant water, which leads to serious hypoxia due to heavy stickiness of potted soil, which is extremely disadvantageous to the root growth of camellias, especially to one-or two-year-old potted seedlings. So before the rainy season.

Camellia: growth habits and cultivation Management of Camellia

1. Replace the basin soil with poor drainage, or loosen the soil in time on the basin surface, and properly mix in a small amount of rotten sawdust and soaked coal ash.

2. Remove the obstacles affecting drainage or correct the position of the gasket on the drainage hole at the bottom of the basin. During the rainy season, pour the basin slightly before each heavy rain, lest Rain Water fall into the basin too much, straighten the basin after the rain stops and pour out the stagnant water in the basin. If you have been damaged by waterlogging, you can first put the pot plant in the shade to avoid direct sunlight, and gradually move it to a suitable place for normal management after it is restored.

Second, prevent long-term rain

Potted camellia is more sensitive to water requirements, too little water, will wilt, yellow leaves, and even cause deciduous leaves; but too much Rain Water will affect plant growth. Especially in continuous rainy days for a long time, camellia plants can not see the sun, but also cause yellow leaves, fallen leaves, affecting photosynthesis to produce nutrient supply plants. So as soon as the weather clears up, you should immediately put the end of the basin into the sun and accept all-day sunshine to avoid emaciation of the branches.

Third, prevent the loss of basin soil.

In the rainy season, the nutrient loss of basin soil, if we do not take corresponding measures, it will affect the normal growth of camellias. Therefore, it is necessary to fertilize the potted flowers timely and appropriately.

Concrete method

1. Break up the dry fertilizer and sprinkle it evenly on the basin surface, then gently loosen the basin soil with tools to mix the soil with fertilizer. After rain, the fertilizer liquid can seep into the basin soil.

2. The amount of fertilizer applied in the rainy season must be small, and it can not be applied until it is fully mature.

Fourth, prevent the overgrowth of plants.

In the rainy season, high air humidity and lack of light often make potted camellias grow branches and leaves, so it is necessary to properly prune and sparse leaves, control watering, apply less nitrogen fertilizer, and, if necessary, use foliar spraying (that is, fertilization outside the roots) to promote branches sturdiness, enhance disease resistance, promote flower bud differentiation, and ensure beautiful flowers in next spring.

V. Prevention of diseases and insect pests

Camellia plants are vulnerable to diseases and insect pests if they are poorly ventilated. Therefore, the position of potted flowers must be properly raised in the rainy season, preferably placed in steps, and potted flowers should not be arranged too densely. In case of cloudy or sunny weather, potted flowers should be fully illuminated to play a role in sterilization and disease eradication. If it is found that the plant has suffered from diseases and insect pests, it should be prevented in time.
