Mammillaria polythele

Mammillaria polythele, commonly known as Nipple Cactus or Many-Nipple Cactus, is a fascinating species of cactus characterized by its small, globular stems and numerous tubercles with prominent nipples. Here is a description of Mammillaria polythele along with some care tips:

Appearance:

Mammillaria polythele typically forms clusters of small, spherical stems that can reach a height of 2 to 4 inches (5 to 10 centimeters). The stems are covered in tubercles arranged in spiral patterns, each bearing distinctive nipple-like projections. The spines are usually white or yellowish and emerge from these tubercles.

Light requirements:

Nipple Cactus thrives in bright, indirect sunlight. Place it near a window or in a well-lit area to provide sufficient light. Be cautious about exposing it to intense, direct sunlight, particularly during hot summer months.

Watering:

Mammillaria polythele is a drought-tolerant cactus that requires infrequent watering. Allow the soil to dry out completely between waterings and then water thoroughly, ensuring excess water drains away. During the winter months, reduce watering frequency to mimic its natural dormancy period.

Soil and potting:

Use a well-draining cactus or succulent mix to plant Mammillaria polythele. Ensure the pot has adequate drainage holes to prevent waterlogging, as this can lead to root rot.

Temperature and humidity:

Mammillaria polythele prefers warm temperatures ranging from 70 to 85°F (21 to 29°C). It can tolerate cooler temperatures but should be protected from frost. This cactus appreciates low to moderate humidity levels, so avoid placing it in excessively humid environments.

Fertilization:

During the active growing season (spring and summer), you can provide a diluted, balanced cactus fertilizer once a month. Follow the package instructions and avoid over-fertilizing, as it can harm the plant.

Propagation:

Nipple Cactus can be propagated through offsets, which are small plantlets that emerge around the base of the main plant. Carefully remove the offsets and allow them to dry for a few days before planting them in well-draining soil.

Pests and diseases:

Mammillaria polythele is generally resistant to pests and diseases. However, occasional problems may include mealybugs or scale insects. Inspect the plant regularly and take appropriate measures to control any infestations. Avoid overwatering to prevent fungal diseases.
