Summer management of camellia

Shade and summer heat

In summer, place the camellia in a shade, a cool and ventilated place from about 8 am to about 5 pm every day. At about 6 pm, move the pot to a place where it can receive night dew. At the same time, make sure the plants are exposed to residual sunlight in the morning and evening.

Moisturizing spray

Water frequently in summer to maintain the humidity in the pot. You can usually spray water on the leaves, pot surface and surrounding ground, which can not only cool down but also maintain humidity. As midsummer approaches, pay attention to controlling watering to promote the formation of flower buds. We strongly remind everyone not to use cold water directly on the roots of the plants when the plants are dehydrated due to high temperature, so as to avoid root damage.

Soil loosening control

If you find that the spring shoots of camellia are too vigorous, you need to loosen the soil, cut off part of the roots, reduce the absorption of nutrients, and apply more phosphorus and potassium fertilizers after entering summer. From July to September, it is recommended to spray the leaves or apply 0.2%-0.3% potassium dihydrogen phosphate, boric acid, etc. on the pot soil to increase the bud formation rate.

Pruning

Too many flower buds will affect the growth in the second year and the quality of flowering will also decrease. Therefore, after August, dense flower buds, deformed flower buds and flower buds inside the crown should be removed. Diseased and insect-infested branches, overgrown branches, and densely grown branches should be pruned in a timely manner to reduce nutrient consumption and maintain ventilation and light transmission.

Prevent pests and diseases

The main disease of potted camellia is sooty mold, which can be sprayed with 500-800 times solution of 50% carbendazim. You can spray it once every half a month, and you will see the effect after two or three times. For insect pests, you can brush them off manually or spray them with pesticides.
