Cacti require well-draining soil that's rich in nutrients. You can use a commercial cactus mix, or make your own by mixing potting soil with sand and perlite.

Watering

Cacti are adapted to survive in dry conditions, so you'll want to be careful not to overwater them. Water sparingly, and allow the soil to dry out completely between waterings.

Fertilizer

Cacti don't require much fertilizer, but a light application of balanced fertilizer once or twice a year can help promote healthy growth.

Cacti are generally resistant to pests and diseases, but they can be susceptible to mealybugs, spider mites, and scale insects. Keep an eye out for any signs of infestation, and treat as necessary with insecticidal soap or neem oil.
