Appearance
Ariocarpus plants are small, slow-growing cacti that typically reach a height of 3-6 inches. They have a flattened, disc-like shape and are usually gray or brown in color. The surface of the plant is covered in small bumps and ridges, giving it a unique texture. Some species may also have a woolly or hairy covering.
Care Guide
Ariocarpus plants require very specific care in order to thrive. Here are some tips for caring for these unique cacti:Water: Ariocarpus plants are adapted to survive in dry conditions and should be watered sparingly. Water only when the soil is completely dry, and be careful not to overwater as this can lead to root rot.Fertilization: These plants do not require regular fertilization. You can feed them once or twice a year with a low-nitrogen cactus fertilizer.Soil: Ariocarpus plants prefer well-draining soil that is sandy or gravelly. Avoid using soil that retains water, as this can lead to root rot.Sunlight: These plants require bright, direct sunlight in order to thrive. Place them in a south-facing window or outdoors in a sunny location.Hardiness Zones: Ariocarpus plants are hardy in zones 9-11.
Common Pests & Diseases
Ariocarpus plants are generally resistant to pests and diseases. However, here are a few issues to watch out for:Mealybugs: These insects can infest the woolly covering on some species of Ariocarpus. Use a cotton swab dipped in rubbing alcohol to remove them.Fungal Diseases: Overwatering or poorly-draining soil can lead to fungal diseases like root rot. If you notice blackened or mushy parts on the plant, remove them and let the plant dry out.
