Are there any black, mushy spots at the base of the plant or the leaves?
Are the leaves yellowing and wilting, the soil around the plant may have started to take on a blue-tinted appearance?
Does your Gasteria have a pale center and deformed growth?
Are there any brown, crusty spots on the leaves?
Overwatering can cause root rot, which shows up as black, mushy spots at the base of the plant or on the leaves. If this happens, saving the plant is rare, but you may be able to grow a new plant from cuttings. To avoid rot water only at the base of the plant, don’t get the leaves wet, allow the soil to dry out almost completely between waterings.
Root mealybugs feed on plant roots of host plants by sucking the sap from the tissues through their mouthparts. The first signs may be the yellowing and wilting of the leaves as it will look like the plant’s health begins to deteriorate. The soil around may start to take on a blue-tinted appearance due to the waxy filaments covering mealybugs body. Remove the infected succulent plant from its pot. Knock off and remove as much soil as possible. Sterilize the plant and root system by soaking the roots in hot water between 115° to 120° degrees Fahrenheit for about 10 minutes. Sterilize or replace the pot.
A pale center and deformed growth are typical signs of too little light. Provide it with at least a few hours of bright indirect sunlight, especially in the winter months. This will provide the vital nutrients that'll be converted into plant sugars.
Too much direct sun may cause scorching. This shows up as brown, crusty spots on the leaves. To avoid this, remember to provide your plant a bright spot, with indirect sunlight. If moving plants to the outdoors in the summer, take plenty of time to allow the plant to adjust. Do not place Gasteria in direct sunlight.
Leaves may on occasion develop black spots or bruises. These black spots may come from damage to the plant’s wax coating, injury, or fungal infection. Avoid this problem by providing plenty of room for growth and good air circulation. Also, try to maintain low humidity levels.

Sreten null
Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
