How to Handle Roses After Repotting
Repotting roses is an important part of the maintenance process, directly affecting the plant's growth status in later stages. The root system in the new environment needs to go through an acclimation period, and improper handling during this time can easily lead to yellow leaves, root rot, and other issues. This article will systematically analyze the four core maintenance points after repotting and specifically answer common puzzles about light management.
Key Maintenance Steps After Repotting
Water Control Techniques
In the first 3-5 days after repotting, stop watering the roots and use a misting spray bottle to spray the leaves twice a day. Use pure water at a temperature close to room temperature, spraying until the leaves are moist but not dripping. During this stage, the soil moisture should be maintained at 40%-50%, which can be checked by inserting a bamboo skewer into the soil.
Taboos on Nutrient Supply
The absorption capacity of the newly repotted rose roots decreases by over 80%, and fertilizing can lead to salt accumulation. It is recommended to start supplementing nutrients 15-20 days after repotting, initially using a dilute liquid fertilizer with an EC value ≤ 1.0, applied at 1/4 of the normal concentration.
Core Points of Light Management
Avoiding Light During the Seedling Period
The first 7 days after repotting require complete shade, placed in an indoor scattered light environment. The light intensity should be controlled between 3000-5000 lux, which can be achieved with a 75% shade rate using a shading net. Ensure the day-night temperature difference does not exceed 8°C, with the night temperature maintained above 15°C.
Gradual Light Adaptation Method
Start implementing the light adaptation plan on the 8th day: increase morning light (6-9 am) by 1 hour each day, for a 5-7 day transition. Use a light meter to monitor and ensure the light intensity gradually increases from 5000 lux to 15000 lux.仍需进行50%遮阴处理 during noon.
Environmental Control Standards
Maintain an ideal temperature range of 18-24°C, with the best air humidity at 60%-70%. It is recommended to use a thermometer and hygrometer for real-time monitoring,配合加湿器或水盘调节 as needed. Special attention should be paid to avoid direct air conditioning, maintaining a gentle air flow of 0.5-1 m/s per hour.
Through scientific maintenance management, roses usually take 2-3 weeks to complete the acclimation period after repotting. When new buds sprout and the leaves become upright, it indicates that the plant has adapted to the new environment. At this point, you can gradually resume normal maintenance, but it is still necessary to continue observing for 2 months to ensure full recovery and growth vitality.
