Frailea buenekeri

The secret for keeping fraileas happy and growing is to pot them in a rich, porous soil with good drainage and aeration, to give them lots of water and let them dry out between waterings. Fraileas do like more water than most other cacti. During winter they like cool and dry places (minimum temperature of 5-10° C) but even light frosts do not harm them. Flowers: Sulphur yellow Cultivation and propagation: Fraileas are tiny plants with comparatively big yellow flowers, often bigger than the whole plant itself. They can be easily grown in a sunny windowsill or a small greenhouse.

Fraileas do like more water than most other cacti. During winter they like cool and dry places (minimum temperature of 5-10° C) but even light frosts do not harm them. Characteristically, during the dry season plants retract completely under the ground, both in the wild and in cultivation too. Occasional light spray of water during the winter helps plants from shriveling up too much. In the summer they like the pot to be filled with water that is quickly absorbed by the plants. Sun exposure: They enjoy full sun. In a shaded position the plants grow faster. Some of the information in this description has been found at desert-tropicals.com, llifle.com and cactus-art.biz
