Gasteria is a genus of succulent plants native to South Africa. These are popular houseplants and are known for their easy care. The name is derived from the Greek word for stomach, gaster, referring to the shape of the flower. They are slow-growing succulents and have dark-green tongue-shaped thick, rough leaves.
Tip: we recommend Etsy for buying plants. Look for the best rated seller you can, and try to buy as close to your home as possible so the plant does not travel too far.
They love sitting under the bright, indirect sunlight. It can tolerate some direct sun, but too much exposure can lead to sunburn of leaves. If the leaves start to turn white or yellow, it means the plant is getting too much sun.
How Often to Water Gasteria
Gasteria is a drought-tolerant plant and can go for long periods without water. Water the plant when the soil is dry to the touch, about once a week or every two weeks. Be sure to drainage as it does not like sitting in soggy soil.
Gasteria is a light feeder and does not need much fertilizer. Fertilize your plant once every spring with Commercially available cacti fertilizer. Do follow the instructions written on the label for the right amount of fertilizer.
Gasteria grows best in sandy, well-drained soil. You can also grow it in a cactus mix with some extra perlite or pumice added to improve drainage.
When To Repot Gasteria
Gasterias are slow growers and do not need to be repotted often. You can repot your plant every 2-3 years or when you see the plant has outgrown its pot. Take the plant out and repot it into a bit larger pot having cacti potting mix.
Being a succulent, it does not need a high humid environment. The average humidity level of the room is good for this plant.
Gasteria can tolerate a wide range of temperatures but prefers to be in cooler environments. Aim for the temperature between 65-85°F (18-29°C).
How To Propagate Gasteria
Gasteria is best propagated by the offsets/baby plants; it produces around the base. These can be removed and propagated in their own pot. Each offset grows into an individual plant, thus adding more plants to your collection. Propagate your plant in the spring as it is the time of active growth for the plant.
