What to do with aloe vera yellow leaves
When aloe vera leaves turn yellow, many growers feel anxious. As a typical drought-tolerant plant, yellow aloe leaves often imply deviations in the maintenance process. This paper systematically sorts out the five core maintenance points and helps plants restore their green vitality through scientific diagnosis. 1. Response plan for sudden changes in the environment 1.1 Aloe vera that has just been moved or changed during the new environmental adaptation period will have temporary yellow leaves, which is a normal phenomenon for plants to activate self-protection mechanisms. Maintain the original maintenance environment for 2-3 weeks, maintain a constant temperature environment of 15-25 ° C, and avoid frequently moving flower pots. 1.2 Progressive environmental adjustment If the maintenance position needs to be changed, a 7-day transition method should be adopted: move 30 centimeters a day and gradually approach the target position to help the plants adapt to changes in light, temperature and humidity. 2. The golden rule of water management 2.1 Diagnosis and remediation of water shortage When the soil in the basin turns white and becomes lighter, use the dipping basin method to replenish water: immerse the flower pot in 1/3 of the height of the water basin, take it out and drain it after 15 minutes. This method can avoid the illusion that the surface layer is wet and the bottom layer is dry. 2.2 Water treatment plan Stop water immediately after over-watering, and tilt the flowerpot 45 degrees to help drain water. Use a bamboo stick to make ventilation holes in the basin soil, and cooperate with a fan for low-gear circulation ventilation to accelerate moisture evaporation. 3. The light control trio maintains direct light for 4 hours a day in spring and autumn. In summer, sunshade nets are used to filter strong light, and full sunlight can be accepted in winter. If sunburn spots appear, they should be moved behind the gauze curtain in time for scattered light maintenance. 4. Tips for soil improvement: Replace the breathable substrate every two years, and mix it according to the ratio of perlite: leaf soil: coarse sand =3:4:3. Regularly use a gardening shovel to loosen the top soil to improve the root breathing environment. 5. Disease prevention system Spray the leaves with garlic extract (100g minced garlic +1 L water) every month, which can effectively prevent and control pests such as red spiders. When signs of root rot are found, immediately remove the rotten root system, soak it in carbendazim solution, and then change the pot to replant it.
Through systematic diagnosis and precise intervention, more than 90% of aloe yellow leaf problems can be improved within 20 days. Keeping in mind the principle of "observation-diagnosis-step-by-step treatment" and cooperating with regular maintenance log records, aloe vera can remain green all year round.
