Crassula are succulent plants belonging to the Crassulaceae family. They are often characterized by their fleshy, dense, rounded leaves, arranged in a rosette or along thick stems. Crassula come in a wide variety of shapes and sizes. Some species have green leaves, while others can have shades of red, yellow, or purple. Crassula are succulents that need moderate watering. As with most succulents, it is important to let the soil dry out between waterings to prevent root rot. Water the plant when the soil is dry to a depth of about 2 to 3 centimeters. In general, watering every two to three weeks is often sufficient. Crassula prefer a bright location with indirect sunlight. They need light to maintain their compact shape and prevent excessive stretching. Place them near a south or west-facing window to provide bright but subdued light.
