About Mammillaria supertexta
Mammillaria supertexta, commonly known as Biznaguita, is a small, globular cactus native to Mexico, forming dense colonies over time. It is characterized by its densely covered tubercles with short, white spines giving it a cottony appearance, and small pink or whitish crown-shaped flowers. Its compact size and attractive texture make it ideal for cactus collections, rockeries, or as an indoor plant in small pots.
Native range
Oaxaca, Mexico
Care tips
It requires abundant direct sunlight for optimal growth and prolific flowering, preferably in a sunny outdoor spot or near a very bright window indoors. Watering should be sparse, allowing the substrate to dry completely between waterings, and almost non-existent in winter to prevent rot. Use a very porous and well-draining substrate, specific for cacti, to ensure water does not stagnate. A common mistake is overwatering, which can quickly rot its roots and base.
How to save a dying Mammillaria supertexta
- Warning signs
- Soft/black base (rot), orange spots (fungus), dehydration (wrinkles, dull color).
- First aid
- Cut affected parts with sterile knife. Apply fungicide. For rot, unpot, clean roots, dry 1 week, repot.
- What kills it
- Overwatering (especially in winter), poor drainage, moisture-retaining substrate.
- Can it be saved?
- Yes, if rot hasn't reached growing tip or dehydration isn't extreme. Act quickly.
