Cacti and succulents are fleshy plants with thick leaves and stems or trunks adapted to store water. They can come in a wide variety of shapes, sizes and textures. Some have rounded, plump leaves, while others have spiky stems or more elongated shapes. Cacti and succulents can range in color from dark green to blue, gray or even purple, depending on the species. Cacti and succulents are plants that prefer to be watered sparingly. Their special water-storing structures allow them to survive in arid conditions. It is essential to let the soil dry out between waterings to prevent root rot. In general, water them when the soil is completely dry. Cacti and succulents generally prefer a bright location with direct sunlight. They need light for healthy growth. Place them near a south or east-facing window to provide them with plenty of light.
