Will aloe vera come back when it turns black?
As a star player in the indoor green planting industry, aloe vera is deeply loved for its unique shape and purifying effect. However, the blackening of leaves during the maintenance process often leaves growers at a loss. This article will deeply analyze the causes of the blackening of aloe vera leaves and provide systematic solutions. Explanation of the reasons for blackening of aloe leaves. Irreversible characteristics of cell necrosis When charred black spots are observed on local aloe leaves, it indicates that the mesophyll cells in this area have completely necrosed. This irreversible damage is like scalding and scarring on human skin, which cannot be restored to its green appearance through routine maintenance. However, timely intervention can prevent the spread of lesions and protect healthy leaves. More than 78% of leaf blackening cases with chain reactions of root lesions are related to root damage. Rotten roots caused by stagnant water will block water transport and cause dehydrated charring of leaves. This phenomenon is often accompanied by characteristics such as the overall weakness of the plant and the first disease of the base leaves. Aloe Vera maintenance and repair strategy three-step method for root saving 1. Remove the pot and inspect: Tap gently on the pot wall to loosen the soil and completely remove the root system. 2. Precise pruning: Use disinfectant scissors to remove brown soft rot roots and retain milky white healthy roots. 3. Rebirth environment: Switch to a breathable substrate with 30% of perlite, and initially control the watering amount and light regulation. The golden rule of aloe vera needs to follow the lighting principle of "full sunshine in winter and half shade in summer." When sunburn is found on the leaves, they should immediately move to a scattered light environment and spray the leaves with vitamin B1 solution (1:1000) to promote repair. The ideal aloe cultivation substrate for pot soil improvement plan should contain: ·40% coarse river sand·30% humus soil·20% vermiculite·10% bone meal·5g of slow-release fertilizer is added every 2 years when pots are changed, which can effectively prevent soil hardening problems. Long-term management of aloe maintenance records the soil drying cycle by establishing a watering log, and adjusts the maintenance plan in conjunction with the environmental temperature and humidity. It is recommended to apply seaweed fertilizer every month in spring and autumn to enhance stress resistance, and maintain the maintenance temperature above 10℃ in winter. After 3-6 months of careful care of the damaged plants, the new leaves will regain their emerald luster.
