Plant care
Light
Mammillaria thrives well in bright indirect light. Direct sunlight can be fine.
Water
Follow drying out in between watering. Excess water can be detrimental.
Soil
The Soil need to be fertile and well drained where there is no water logging. Fertile soil rich in humus can be prepared.
Fertilizer
Fertilize Mamillaria in every two to four weeks during spring and summer. Use a general purpose liquid houseplant fertilizer, but dilute the mixture to one-third to one-half the solution recommended on the container. Withhold fertilizer during the fall and winter months.
