How to Grow and Care
If you can grow cacti and succulents successfully, you can likely grow the popular Rebutias without too much trouble. Their water and light requirements are fairly typical for many cacti species, including a cooling period in the winter to promote better blooming. Watering should be done carefully, allowing the plant to almost dry out between waterings. The cactus mustn't be exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. For the best viewing, instead of propagating your offsets, let the plant for a large cluster. When it blooms, this will make a stunning display. Lastly, make sure to fertilizer during the growing season for the best results.
Repot as needed, preferably during the warm season. To repot your Rebutia, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
