How to Care for a Flowering Cactus

By M.H. Dyer ; Updated September 21, 2017

If you love the idea of decorating your living space with houseplants but you're short on time, or if you don't have room for a Boston fern or philodendron, a flowering cactus may be just the ticket. A flowering cactus has only a few basic needs that will take only a few minutes of your time, and and most cacti require very little space.

Locate flowering cactus in bright, but indirect light. Too much light can fade the blooms or cause the blooms to drop off prematurely. If you don't have adequate light, you can put flowering cactus under a grow light.

Keep flowering cactus in a fairly warm environment. Night time temperatures should be between 55 and 60 degrees. During the day time, flowering cactus will do well in temperatures of about 70 degrees.

Water flowering cactus until water runs through the drainage hole in the bottom of the pot, but never let the pot sit in water, which can cause disease and rot. Feel the soil with your fingers before you water, and allow flowering cactus to dry slightly between each watering.

Feed flowering cactus an all-purpose water-soluble houseplant fertilizer or tomato fertilizer once a month during the growing season. Don't fertilize the cactus in December and January.


Things You Will Need

  • Grow light (optional)
