How Do Healthy Aloe Vera Plants Look?

Whether Aloe leaves are healthy or not depends on the leaves. Some aloe leaves will penetrate yellow mucus, that is, the root system does not grow well and there is too much water. If the leaves of aloe are curled up, thinned and atrophied, it is a lack of water, and the drooping leaves are a lack of sunshine.

The Symptoms of an Unhealthy Aloe Vera Plant

If the yellow leaves of aloe are thin and curly, if it is not just on the pot without slow seedling success, it may be caused by long-term water shortage. Although aloe is dry, it should be watered in time when the bottom leaves are slightly soft. If the water is insufficient for a long time, the leaves will become softer and thinner. In the growing period of aloe, we lack nutrients for aloe, which will also cause the leaves to become thin and soft. These are unhealthy manifestations of aloe.

Cause & Solution for Yellow and Brown Aloe Plant

Overwatering

Excessive watering leads to yellowing of aloe leaves: after being injured, the young leaves of aloe first turn pale yellow, and then the old leaves turn yellow gradually.
  • Repot And Reduce Watering
Overwatering is generally common. The changes during this period are generally from green to yellow. In fact, we can control watering. For example, we loosen the soil of aloe before watering, and then water it, which is conducive to the air permeability of the soil. At the same time, we can reduce the residue of ponding.

Underwatering

Aloe needs enough water during its growth. If it is watered too little, it will lead to the lack of water in aloe plants, which will make aloe leaves dry and yellow.
  • Water Your Aloe When The Soil Is Dry
Water shortage has an impact on any plant. The solution is simple. We are actually the same as the watering process. We can loosen the soil under aloe first, and then water it when the soil is dry. Do not water too much. In real life, many people try to water when they see that plants are short of water. In fact, the effect is even worse.

Excessive Heat

Excessive Heat will lead to the yellowing of aloe leaves, which is very easy to cause the withered tip or edge of young aloe leaves, or the yellow leaves fall off.
  • Acclimate Your Aloe Plant To The Outdoors
Excessive heat will cause the leaves of Aloe Vera to turn red brown, and the leaves feel hard light, which may be caused by too strong light. Although aloe likes sunshine, too strong light is also harmful to aloe. We can move the potted aloe to a place with scattered light and bright light for maintenance for a period of time, and it will slowly recover.

Drafts or Cold Air

If the room temperature is too low in winter, aloe vera will be slightly damaged by freezing, and its leaves will turn yellow.
  • Keep Aloe Plants Warm
Too low temperature will also affect aloe. When the temperature is lower than 10 degrees in winter or high in summer, we must timely move aloe from outdoor to indoor, so as to give plants a normal growth environment.

Sunburn

Aloe likes light, but cannot be exposed to the sun. If aloe irradiates strong light in summer, it will burn the leaves and cause aloe yellow leaves.
  • Keep Aloe Plants Out Of Direct Sun
Aloe is actually very afraid of the sun. Therefore, when we plant aloe, we must not let the sun shine directly on the aloe, which is easy to cause the leaf tip of aloe to wither. At the same time, we can put aloe next to the windowsill to receive indirect light, and use curtains to cover it, which is conducive to the normal growth of aloe.

Too much fertilizer

  • Refresh the Soil and Fertilize Aloe Plants Sparingly
When the leaves of aloe become yellow due to excessive fertilization, we should stop fertilization immediately. We can irrigate with clean water to drain the fertilizer solution as soon as possible to avoid further deterioration. If the situation is serious, we can remove the aloe basin, replace it with new soil, and re maintain and manage it. In addition, pay attention to the fertilization method in the later stage, and apply a small amount each time. In addition, we must use low concentration fertilizer. It is strictly prohibited to use high concentration fertilizer to avoid fertilizer damage and affecting growth.

Pests

Common diseases and pests of aloe include rust, brown spot and leaf blight, which can lead to yellow leaves and even rotten roots. Insect pests include scale insects and red spiders. When insect pests occur, they will also cause leaves to turn yellow.
  • Solution
When we take care of Aloe Vera at ordinary times, we should do a good job in ventilation. When we find that Aloe yellow leaves can be removed in time. In severe cases, it can be sprayed 1000 times of chlorothalonil 75% powder. Spray once in 2-3 weeks and 3-4 times in a year. For the pests of aloe, we can spray 40% Omethoate 2500 times and spray it every 4 days for 2-3 consecutive times.

Diseases

The common diseases causing yellow leaves of aloe mainly include anthrax, brown spot, leaf blight, white silk and bacterial diseases. Family potted aloe should focus on disease prevention. Before the disease occurs, we can select disease resistant varieties and high-quality disease-free seedlings, strengthen fertilizer and water management, and apply protective agents to prevent the disease. When the disease has occurred, chemical control can be supplemented to control and prevent the development and spread of the disease, but at this time, the yellow leaf spots of aloe can not be eliminated, and its ornamental value has decreased.
  • Solution
Before the occurrence of aloe disease or after the diseased plant has removed the diseased part, apply 0.5 ~ 0.8 lime equivalent Bordeaux solution (i.e. 0.5 ~ 0.8 kg of copper sulfate and lime per 100 kg of water) to the leaf surface of aloe, which can effectively prevent and inhibit the invasion and spread of bacteria, resulting in the yellow leaves of Aloe.
After the occurrence of aloe diseases, we can use the therapeutic agents of internal absorption and conduction, such as tobuzin and ruidamycin, as well as antibiotics, such as streptomycin sulfate, agricultural streptomycin, chunleimycin and Jinggangmycin, which can kill the pathogens in Aloe and control the spread of diseases.
