Cultivation: Plants are slow growing to start but are easy to grow and require little care once they have reached a nice flowering size. F. glaucescens is suited for any rich, well drained soil in full sun throughout the year. Pot culture: grow best in a fairly roomy, well-drained container filled with a porous cactus soil mixture that doesn't contain too much humus. To ensure robust plants water and fertilize during the aestival growth cycle, this plant need plenty of water (indicatively: about once a week) But it is necessary to avoid wetting the bodies of these plants while they are in sunlight. A wet cactus in the sun light can cause sun burning, which can lead to scars or even fungal infections and death. In winter keep completely dry at 10C.  This usually aids in maintaining a healthier plant, but it can tolerate sporadic light frost.

Propagation: Seeds are the typical way of reproducing. These cacti will easily grow from seeds and some from cuttings.
