Cultivation and Propagation: This tropical cactus prefers loves warm moist, humid conditions and mist spraying is a must in summer. Water regularly during the growing season and use a very draining mineral potting substrate. At the onset of winter, do not water. Uebelmannias need heat all year round and extra winter heat, minimum 10C is best. Avoid any frost. Keep cool in summer. It prefers a half-sun position and possibly afternoon shade in summer. If you can place it so that this occurs the plant will be much happier.
Propagation:* Grafting. If possible using a rootstock that is more hardy than the Uebelmannia is the ideal.
