Mammillaria zeilmaniana 7cm

Mammillaria zeilmaniana
Zeilmaniana is a fast growing mammillaria growing 8cm across and clustering with offsets, rings of 1cm crimson flowers appear in late winter on mature plants. Zeilmaniana is a soft bodied cactus and so care must be taken not to overwater them.

Position - under protected partially shaded positions outdoors. Indoors only in sunny positions otherwise they will become long and produce less offsets. Flowering will only occur in good light.
Watering - can be watered all year round and grow fastest in the warmer months. Plants will survive without water for very long periods and remain compact when dry. Feeding 25% of recommended dosage monthly in growing period. The less fertiliser, the better the shape of the plant. Fertilisers high in nitrogen can produce larger plants with less colour.
Repotting can be left to overgrow their pots, or repotted in the warmer months in almost any well drained potting mix.
