What are the reasons for aloe not adapting after repotting
As a common succulent plant in homes, aloe often困扰s plant lovers with problems such as soft leaves and stagnant growth after repotting. This article systematically analyzes the key points of maintenance during the adaptation period after repotting, focusing on three core issues: root care, environmental control, and water management.
One, root health determines survival rate
1.1 Typical manifestations of root damage
If the main root is broken or the capillary root is torn due to rough operation during repotting, the plant will show stress responses such as wilted and drooping leaves and soft base. After root damage, the absorption function decreases, which directly affects the transport of water.
1.2 Four-step method of scientific root pruning
① Retain the main root length of about 15cm; ② Trim blackened and rotting roots to retain healthy roots; ③ Apply carbendazim powder to the incision; ④ Dry the roots for 2-3 days to wait for the wound to scab. Scientific root pruning can stimulate the germination of new roots and improve the success rate of potting.
Two, environmental regulation promotes recovery
2.1 Temperature sensitive period management
The optimal growth temperature for aloe is 18-28°C. In winter, the nighttime temperature should be maintained above 10°C when repotting, and avoid high temperatures above 32°C in summer. It is recommended to repot when the average daily temperature in spring and autumn is around 20°C, which can increase the growth rate of new roots by 40%.
2.2 Light transition plan
Place in a diffused light environment for the first 7 days after repotting to avoid direct sunlight burning the leaves. Starting from the second week, gradually increase the duration of sunlight exposure, extending 1 hour of direct sunlight each day until the full sunlight state is restored.
Three, golden rules of water management3.1 Judgment of watering timing
No watering is allowed within 72 hours after repotting, and water should be slowly added along the edge of the pot when the potting soil is completely dry. The humidity can be detected by inserting a bamboo skewer:补水 can be added when less than 1/3 of the soil taken out by the bamboo skewer is moist.
3.2 Soil improvement plan
It is recommended to use a matrix formula of pearl rock: vermiculite: decomposed leaf soil = 3:2:5, with a porosity of over 35%. Change the potting soil every two years, and retain 1/3 of the original soil to protect the roots when repotting, to reduce the stress response caused by sudden changes in the environment.
By using the three-stage management method of root care, environmental control, and scientific watering, the survival rate of aloe repotting can be increased to over 90%. It is recommended to combine regular observations, and when the leaves recover and new buds sprout, it indicates that the plant has successfully passed the adaptation period.
