Summer management of Camellia

Shade for summer

In summer, place Camellia in a shady, cool and ventilated place from about 8 a.m. to about 5 p.m. every day, and move the basin to a place that can accept night dew at about 6 p.m. At the same time, pay attention to letting the plants receive the residual light of the sun sooner or later

Water spray Moisturizing

Water frequently in summer to keep the humidity in the basin. At ordinary times, you can spray water on the leaf surface, basin surface and surrounding ground, which can not only cool down, but also maintain humidity. In midsummer, we should pay attention to controlling watering and promoting the formation of flower buds. It is important to remind you not to directly water the root of the plant with cold water under the condition of high temperature water loss, so as to prevent damaging the root

Loosen the soil and control the length

If it is found that the spring shoots of Camellia are too busy, it is necessary to loosen the soil, cut off some roots, reduce the absorption of nutrients, and increase the application of phosphorus and potassium fertilizer after summer. From July to September, it is recommended to spray foliar or pot soil with 0.2% - 0.3% potassium dihydrogen phosphate and boric acid to improve the bud pregnancy rate

Pruning and thinning

Too many flower buds will affect the growth of the second year and the flowering quality will decline. After August, the bud and corolla should be removed, and the bud should be deformed. The diseased branches, overgrown branches and dense branches should be trimmed in time to reduce nutrient consumption and maintain ventilation and light transmission

Prevent diseases and insect pests

The main disease of potted camellia is soot, which can be sprayed with 50% carbendazim 500-800 times solution. It can be sprayed once a half month, and the curative effect can be seen two to three times. For pests, it can be brushed off manually or sprayed with medicine
