Astrophytum myriostigma cv. Onzuka - 5 seeds
This Astrophytum is a relatively easy-to-grow species. It needs a mineral, well-draining soil, with little humus. Water sparingly from March till October, letting the soil getting dry before watering again: be careful not to overwater, because this plant’s epidermis may crack. To avoid root rot, keep it dry from the beginning of autumn to the end of winter. It is theoretically hardy to -7°C, but during cold months keep it in a cool place. It does well from full sun to light shade.
