What to Do When Aloe Vera Leaves Dry Out
As one of the easiest plants for beginner gardeners to care for, the issue of drying leaves in aloe vera often catches people off guard. This article systematically analyzes five causes of dried leaves, from environmental adjustments to disease prevention and treatment, guiding you step by step to restore the vitality of your aloe vera.
One: Move to a Shaded Area and Rehydrate
Environmental Adjustment
Continuous exposure to sunlight for three days in summer can cause leaf dehydration. It is recommended to immediately move it to a scattered light environment and maintain a room temperature of 18-28°C. A north-facing windowsill or a balcony with 40% shading is the best choice.
Rehydration Techniques
Use the pot immersion method to rehydrate: immerse the pot in a water basin for 15 minutes, then drain after the soil is completely moist. Subsequently, maintain the principle of watering when the topsoil feels dry, about every 5-7 days in summer and every 15-20 days in winter.
Two: Scientifically Supplement Potassium
Symptoms of potassium deficiency often manifest as the edges of lower leaves becoming scorched. It is recommended to apply banana peel fermentation solution (diluted 1:50 with water) or wood ash extract (100g per liter of water) monthly. Avoid mixing with calcium-based fertilizers to prevent antagonistic effects.
Three: Root Diagnosis and Treatment
Partial drying of leaves is often accompanied by root problems: 1. Gently tap the pot wall to loosen the plant and observe the root ball state. 2. Trim blackened and rotting roots to healthy parts. 3. Soak in a solution of carbendazim 800 times for 20 minutes for disinfection. 4. Repot using a breathable red pottery pot.
Four: Optimize Cultivation Substrate
Recommended golden ratio: • Decomposed leaf soil 40% (provides organic matter) • Coarse river sand 20% (enhances drainage) • Akadama soil 20% (regulates pH) • Perlite 20% (increases porosity). The potting soil should be changed every two years to avoid salt accumulation.
Five: Comprehensive Control of Leaf Blight
In the early stages of the disease, small brown spots can be seen. It is necessary to immediately: 1. Isolate the affected plant. 2. Cut off the diseased leaves and apply wood ash. 3. Alternate spraying with mancozeb (1:1000) and pyraclostrobin (1:1500). 4. Strengthen ventilation to reduce humidity.
By systematically investigating the five main causes and combining them with the correct treatment measures, 90% of dry leaf problems can be improved within 2-3 weeks. In daily maintenance, pay attention to maintaining day-night temperature differences and regularly rotating the pot for even light exposure, which will keep the aloe vera always green and full.
