Bolivia & Argentina
Rebutia are small, attractive cacti, globular in form that usually form a small clump. They freely produce flowers that are relatively large in relation to the body. Flowers are funnel-shaped with floral tubes that often extend and curve upwards over the plant. They have no obvious ribs, but do have regularly arranged tubercles.
Rebutia albiflora is up to 7 cm in diameter up to 10 cm tall. It can grow in clumps 10-15 cm wide. The especially notable characteristics of this cactus are its dark stem colour, emphasized by the small, white areoles, and its large, 3.5 cm wide pure white flowers.
Rebutias thrive in bright light and a range of conditions. Many species can be grown in partial shade to full sun. However, as these are mountain species, they do not appreciate high temperatures, which should be avoided.
It requires rich, fast draining porous cactus soil. Repotting may be done every 2-3 years. Ideally use 50% Potting Soil + 15% cocopeat + 25% Organic manure / Vermicompost + 5% charcoal chips + 5% perlite.
Water the soil abundantly when it is dry to the touch. Allow soil to drain thoroughly before watering again. Allow the soil mix to become nearly dry between waterings, but then water thoroughly. Suspend watering in the winter, but mist occasionally.
During the growing season, fertilize with a cacti fertilizer mix.

For watering cacti, the golden rule is to make sure the soil is completely dry before watering! This will stop the roots from rotting. It is advised to always use a pot with a drainage hole so that excess water can get drained out. If kept in a sunny area, you will need to water it once every week. If it is in a semi shaded or filtered light area, you might need to water it once in 2 weeks.
Cacti like soil that is well aerated and fast draining. You can fertilise the cactus in the summer months when it is in its growing season. During the winters it is best to cut back on any fertiliser and let the plant rest.
