Mammillaria cacti thrive in bright, indirect sunlight. Place them near a south or west-facing window to provide adequate light.
Mammillaria cacti are sensitive to overwatering. Allow the soil to dry out completely between waterings. Typically, this means watering every 2-4 weeks.
Mammillaria cacti do well in low humidity conditions, making them suitable for indoor environments.
Keep your Mammillaria cactus in a warm environment. They prefer temperatures between 70-100°F (21-37°C) during the growing season.
Choose a pot that allows for about an inch or two of space around the cactus. Mammillaria cacti generally don't need frequent repotting.
Feed your Mammillaria cactus with a diluted, balanced cactus fertilizer during the growing season (spring and summer) every 4-6 weeks.
Use a well-draining cactus mix or create your own by adding sand or perlite to regular potting soil. Ensure the pot has drainage holes to prevent waterlogging.
Remove any dead or damaged growth by gently pulling or cutting it off with clean, sharp scissors or pruning shears. Be cautious as Mammillaria cacti can be prickly.
Keep an eye out for common cactus pests such as mealybugs and spider mites. If an infestation occurs, treat with insecticidal soap or neem oil.
