Does the Camellia need watering after transplanting?
As one of the top ten traditional famous flowers in China, the maintenance management of Camellia after transplanting is directly related to the survival rate of the plant. Mastering the scientific watering methods and transplanting time points can help the Camellia quickly adapt to the new environment. This article will comprehensively analyze key technologies from moisture management to the survival cycle.
Moisture Management for Transplanted Camellia
Watering Amount Control
Water thoroughly for the first time after transplanting to make the roots closely contact with the soil. Then keep the soil moist without waterlogging, spray water twice a day in summer, and supplement water every 2-3 days in spring and autumn. Use a moisture meter to monitor and maintain the substrate moisture at the optimal level of 75%-85%.
Water Quality Treatment
In the northern regions, it is necessary to adjust the water pH with ferrous sulfate (0.2% concentration) to keep the pH value between 5.5-6.5. It is recommended to use tap water or rainwater that has been exposed to sunlight for 3 days, and the water temperature should be within 5°C of the ambient temperature to avoid stimulating the roots with cold water.
Humidity Management
Maintain air humidity above 60% by misting and place moist sphagnum moss around the plant. Use a transparent plastic bag to cover the pot to keep the microenvironment humidity, and vent for 2 hours daily to prevent mildew.
The Survival Cycle of Transplanted Camellia
Seedling Recovery Period
15-30 days is a critical observation period. After new fine roots form, the leaves regain luster, and the terminal buds begin to swell. If continuous leaf shedding and shriveled branches appear after 30 days, check if the roots are rotting.
Environmental Adaptation Period
60-90 days after transplanting, the plant enters a stable growth phase, and new shoots reaching 3-5cm indicate full survival. At this time, apply a diluted solution of potassium dihydrogen phosphate (2000 times) to promote bud differentiation.
Scientific Transplanting Steps for Camellia
Best Transplanting Time
In the Yangtze River Valley, it is suitable to transplant from late October to mid-November when the soil temperature is stable at 15-20°C, which is the best for root activity. Avoid transplanting in spring to prevent affecting the flowering of the same year.
Soil Ball Treatment
The diameter of the soil ball should be 6-8 times the diameter of the plant's base, and it should be tied and fixed with straw rope. The main roots should retain a length of ≥20cm, and the damage rate of lateral roots should be less than 15%.
Substrate Formula
Recommended ratio: decomposed leaf soil 40% + red jade soil 30% + pine bark 20% + bone meal 10%. Add 50g of sulfur powder per cubic meter to adjust the pH value, ensuring the EC value is between 1.2-1.8mS/cm.
By precisely controlling water supply and transplanting operations, combined with temperature and humidity adjustments, the survival rate of transplanted Camellia can reach over 95%. It is recommended to use a 800 times solution of carbendazim to drench the roots monthly to prevent diseases and ensure healthy plant growth.
