Care guide
Most cacti need plenty of sunlight to grow and thrive. Place your cactus in a sunny spot where it can receive direct sunlight for several hours a day. A south-facing window is usually the best location indoors. If growing cacti outdoors, ensure they have access to full sun.
Cacti generally prefer warm temperatures. They thrive in temperatures between 70°F and 90°F (21°C and 32°C) during the growing season. Some cacti can tolerate cooler temperatures, but most cannot withstand frost. Protect them from freezing temperatures, especially during winter.
Cacti are adapted to survive in dry conditions, so they require infrequent watering. Water your cactus thoroughly but allow the soil to dry out between waterings. The frequency of watering depends on various factors such as the size of the pot, type of cactus, and environmental conditions. It's better to underwater than overwater, as cacti are susceptible to root rot.
Cacti need well-draining soil to prevent waterlogged roots. Use a specialized cactus or succulent potting mix, or create your own by combining regular potting soil with coarse sand or perlite. This type of soil allows excess water to drain away quickly. Potting: Choose a pot with drainage holes to ensure proper drainage. The pot should be slightly larger than the root system to allow for growth. Repot your cactus every few years when it outgrows its current pot. Handle cacti with care, as their spines can be sharp.
Cacti have low nutritional requirements. Feed them with a balanced, water-soluble fertilizer formulated specifically for cacti and succulents. Apply the fertilizer during the growing season, typically from spring to early fall. Follow the package instructions for the appropriate dilution ratio and frequency.
Most cacti prefer low humidity levels. They are adapted to arid environments, so avoid misting the plants or placing them in overly humid areas. Ensure good air circulation around the plants to prevent the growth of mold or fungus.
Pruning cacti is generally not necessary, but you can remove any dead or damaged parts with clean, sharp tools. Be cautious when handling spiny cacti and use protective gloves if necessary.
Cacti are generally resistant to pests, but they can occasionally be affected by common houseplant pests like mealybugs or scale insects. Inspect your cactus regularly and treat any infestations promptly. You can use insecticidal soap or a mixture of water and alcohol to clean the affected areas.
