The post-planting management of Camellia oleifera mainly includes the work of watering, replanting, loosening soil, weeding, topdressing, and pest control.
Watering and Drainage: During the high temperature season in summer, due to the high temperature, the amount of water transpiration within the tree is large, so timely watering and drought relief are required. Camellia planted in low-lying land should pay attention to drainage during heavy rain.
Replanting: When tea leaves are sprouted and displayed, the survival of the trees must be checked in time. If planting can not survive, replant as soon as possible.
Loose soil: Weeding and weeding once in the year, and weeding twice every year (2 to 3 years), the first time in May to June, and the second time in late August to September. The depth of loose soil is generally 3 to 5 cm. Afforestation should be shallow in the year and deepen year after year. The saplings should be lighter and deeper outwards.
Top dressing: Planting appropriate thinner fertilizer after planting in the June to July of the year. Fertilizers are dominated by nitrogen fertilizers. In the second year of March, the new shoots are planted with effective nitrogen fertilizer in the first half of the month, 0.1-0.3 kilograms per plant. In early December, 5-10 kilograms of soil miscellaneous manure or manure per plant is used as overwintering fertilizer, which increases year after year as the tree grows.
Plastic surgery: During young age, trimming should be done lightly to control leggy branches, thinning weak lateral branches, and promoting lateral branch growth to form low cylindrical crowns. It is necessary to keep as many branches as possible, so that the main trunk will sprout new shoots and expand the canopy, leading to early results.
