Mammillaria sheldonii (100 seeds)

Mammillaria sheldonii. It is a small cylindrical cactus simple or with several heads from base of the plant, with white radial spines and dark brown hooked centrals. The flowers are pink with darker midviens and typically with green stigmas. 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: March 2020
