Mammillaria bertholdii 2.7-3 cm grated.

Diameter: 3cm

Mammillaria bertholdii is a fascinating and relatively rare species of cactus, highly prized by collectors for its unique appearance and slow-growing nature. Here's a quick rundown:

Overview

Family: Cactaceae

Origin: Native to Oaxaca, Mexico

Habitat: Grows in rocky, limestone-rich soil in dry, arid environments.

Appearance

Size: Miniature cactus, often just a few centimeters wide.

Body: Soft, flat, disc-like shape with a green to bluish-green hue.

Areoles: Unlike typical Mammillarias, it has small, fuzzy areoles without obvious spines.

Tubercles: Geometrically arranged and flat, giving it a somewhat cryptic look that blends into its surroundings.

Flowers: Small, bright pink to magenta blooms emerge from the center during the growing season (usually spring to summer).

Growing Tips

Light: Needs bright, indirect light; can tolerate some morning sun.

Watering: Very sensitive to overwatering — use the "soak and dry" method and reduce watering in winter.

Soil: Well-draining cactus mix, ideally with added pumice or perlite.
