When planting, the roots of camellia japonica l should be unfolded and not excessively bent to prevent the root system from being crushed by the soil during planting. The soil above the roots should be properly depressurized, so that the roots and soil are closely connected to improve the water absorption capacity of the roots.

2. Watering in seasons

After planting Camellia japonica L, pay attention to watering, because Camellia japonica L also has strict water requirements. Keep the soil moisture when watering. Too dry will cause death due to lack of water, and too wet will rot the roots. The amount and frequency of watering will also change due to the change of seasons.

It is most suitable to water less in winter and more in summer. Water, every time you water as much as possible, but not water accumulation, do not water against the roots of the tree, to avoid root damage.

3. Light management

Plants must undergo photosynthesis in order to grow. Camellia japonica L planting technology must control light. Camellia japonica L is suitable for growth in a warm climate, and the temperature is 15℃～25℃. In summer, the maximum temperature should not exceed 36℃. To prevent burns, pay attention to the shade.

Proper fertilization will promote the blooming water of Camellia japonica L. During the growth of Camellia japonica L, fertilization should be continuously applied to supplement nutrients. Generally, organic fertilizers are selected as fertilizers. This fertilizer has a long-lasting effect and is not easy to lose. It will be used more than other fertilizers. Potassium fertilizer should be used when growing Camellia japonica L, which can promote the development of root type. Nitrogen fertilizer should be used when flowers germinate, which can promote the growth of flower buds. Phosphorus fertilizer should be used when blooming, which can increase the vividness of flowers.

5. Timing pruning

There are three points to pay attention to when pruning Camellia japonica L. The first is to cut off the broken branches. The second is to trim according to the needs. The third is to avoid the top effect of Camellia japonica L. The main branch should be cut off and how long. Side buds prevent the branches from being too high to waste space.

6. Wipe buds and sparse buds

Smearing buds is to remove the axillary buds on the branches of Camellia japonica L, and concentrate the nutrition to the sprouting flower buds of the lateral branches. Although bud thinning reduces the number of flower buds, it can ensure the quality of the flowers. Just leave one bud on each branch and cut off the remaining side buds to avoid nutrient dispersion.

7. Change pots and soil

Camellia japonica L flowerpots are of different sizes. According to the growth stage of Camellia japonica L, change the pots and soil frequently, otherwise the growth of Camellia japonica L will be inhibited.

Some small stones, coarse sand, etc. can be added to the pot. The soil will be as permeable as possible, the root system will develop, and the branches will flourish.

8. Control pests

Camellia japonica L has different degrees of pest damage except in winter. Aphids often appear on the branches and leaves of Camellia japonica L, sucking nutrients from the branches, causing the leaves to shrink and fall. If you find that there are aphids, you can use 1000 times of 50% dichlorvos to spray once every 10 days or so for 3 times. In daily life, pay more attention to observation and timely treatment.
