Mammillaria hahniana

Mammillaria hahniana , nicknamed "old lady cactus" because of its soft and woolly appearance, is a small species of cactus very popular in cactus collections. Native to Mexico, it is recognizable by its globular body, covered with fine white spines and a kind of woolly down that gives it a cottony appearance. The cactus forms a compact rosette, often solitary, but it can also group together over time to form small colonies. Its ring-shaped flowers, which usually appear in spring or summer, are pink or purple, and add a pleasant contrast to the green of the cactus. In autumn, this cactus sometimes produces small red fruits. Mammillaria hahniana Care Light : Mammillaria hahniana appreciates bright, direct light . Place it in a sunny spot, such as a south-facing window. A lack of light can slow its growth and prevent it from flowering. Watering : As with many cacti, it is essential to allow the soil to dry out completely between waterings. Water sparingly in spring and summer (about every 10 to 14 days), but reduce watering in the fall, and stop almost completely in winter , when the plant goes dormant. Avoid waterlogging in the pot, as this can cause root rot. Humidity : Mammillaria hahniana prefers a dry environment and does not require additional humidity. It tolerates dry air in homes well, making it an ideal houseplant. Temperature : This cactus thrives in warm temperatures, between 18 and 24°C . It tolerates cooler temperatures in winter (down to about 10°C), as long as it is kept dry. Protect it from frost, as it does not tolerate temperatures below 0°C. Substrate : Well-draining soil is crucial. Use a special cactus and succulent mix or a lightweight potting soil mixed with coarse sand or perlite to ensure quick drainage. Fertilization : During the growing season (spring and summer), you can apply cactus fertilizer once a month, diluting the fertilizer to half the recommended dose. No fertilization is necessary during the winter. Repotting : Mammillaria cactus does not need to be repotted frequently. Repotting every 2 to 3 years, in the spring, is sufficient, making sure to choose a pot with excellent drainage. Use gloves or a cloth to handle the cactus to avoid pricking yourself. Flowering : With good light conditions, this cactus flowers regularly in spring or summer. Its pink flowers form a ring around the top of the plant, adding a colorful touch to its globular shape. Propagation : Mammillaria hahniana can be propagated by cuttings of suckers if it forms groups, or by seed. Propagation by seed is longer, but quite common for this type of cactus. Toxicity : This cactus is not poisonous, but its spines can cause minor injuries. Handle with care. Mammillaria hahniana is an easy-care decorative cactus, ideal for those who like low-maintenance plants. With its colorful flowers and fluffy appearance, it brings a touch of charm to any indoor plant collection.
