The amount of fertilizer to be applied to the camellias usually depends on the timing of the application.When potting or repotting, it is usually necessary to apply base fertilizer, usually organic fertilizer or compound fertilizer, which can continuously provide comprehensive nutrients.In the sprouting period of spring, thin fertilizer water is generally used, phosphorus and potassium fertilizers are applied in summer, and liquid fertilizer is used in autumn and winter.In addition, in order to provide an acidic environment, alum can be used to fertilize water at ordinary times.
The interval of fertilization is different in different seasons.Usually in spring, fertilizer should be applied every 17 days.In summer, because of the high temperature, the growth of plants is relatively slow, which can prolong the interval of fertilization.In autumn and winter, during the flower bud differentiation period of the plant, fertilizer is usually applied every week.But as the temperature drops, the plants stop growing and need to stop fertilizing.
According to the type of fertilizer, the method of fertilizing camellias is also different.If solid fertilizer is applied, granular fertilizer is usually used, which needs to be buried in the soil and kept away from the roots.Do not water immediately after fertilizing, usually every other day, which is more conducive to absorption.If it is liquid fertilizer, it is generally used directly to irrigate roots.Foliar fertilizer should be sprayed on the leaves.
Excessive fertilization will cause fertilizer damage, and in serious cases, it may burn the root system and affect the growth of plants.Therefore, if you fertilize too much, you need to wash the pot soil with clean water immediately to wash away the residual fertilizer.If the heavy fertilizer has burned the root system, you need to remove the plant from the pot, inspect and trim the damaged area, and put it in a cool place to dry.Then prepare new pots and soil and plant them again.
