Mammillaria centricirrha (Mammillaria magnimamma) (100 seeds)

Mammillaria centricirrha. (Cactaceae) Native to Mexico. It is a perennial stem succulent solitary at first, later branching basally (or dichotomously) to form large mounds up to 50 cm in diameter (or more) barely rising above ground level. Sowing : Fill a pot with a moist, gritty, loam-based compost, or cacti compost. Gently firm down and level the surface. Scatter your mixed cactus seeds over the surface, taking care not to sow them too thickly. Gently sprinkle a thin layer of vermiculite or fine grit over the seeds, covering the whole surface of the compost. Leave the pot in a greenhouse or on a warm windowsill, covered with a clear plastic bag to preserve soil moisture. Seedlings will develop within a few weeks. Remove the plastic bag and water when the compost becomes dry, but spray the surface with water regularly, to keep it moist. Locality: Ex Hort. Harvest: January 2023
