How to Grow Rat Tail Cactus Cuttings

You can also line the pot with organic materials like sphagnum moss for even better growth.


In the growing season, water your rat tail cactus cuttings regularly for keeping its soil rather moist. As you get closer to fall, reduce the irrigation and stop completely in the winter. However, if the soil is completely dry during the dormancy period, water it lightly. You will not need to do this more than twice during the winter.

The temperatures between 45° F to 50° F are the best for Aporocactus flagelliformis. It is not frost-hardy; however, it can tolerate temperatures as high as 90° F.

During the summer, early autumn, and spring, the rat tail cactus can grow perfectly in room temperatures. But during the winter, you will need to provide a cooler place for it to survive later.


Fertilizing can encourage producing rat tail cactus flowers and better growth. For feeding, use a diluted liquid cactus fertilizer every month in spring and summer. Dilute the fertilizer to a mild strength.
