Rhipsalidopsis is a small genus of flowering plant in the family Cactaceae, native to southern Brazil. Like other members of the tribe Rhipsalideae, its species are epiphytes, growing on trees. The flat succulent leaf segments is one of the unique characteristics of Rhipsalidopsis.

CARE TIPS:

Bud formation usually starts after the first of the year and the dry period needs to continue until the buds are visible. After flowering has finished and the days are getting longer and warmer, the plants begin their growth mode. At this time watering is increased and fertilizer can be added. As with most succulents, bring the soil to near dryness between waterings and then thoroughly saturate the potting mix.

Rhipsalidopsis are moderate feeders but if you fertilize regularly, it will give you abundant growth and flowers. Fertilizer can be added in a soluble form using a balanced formulation i.e. 5-7-3 or a 10-10-10 when you water. Or plants can be top dressed with an organic granular fertilizer.

TRICKS TO BLOOMING

The flowering cycle starts right around Easter, hence the name Easter cactus and flower bud set is induced by dry soil and cool temperatures in early winter. As fall approaches, soil moisture should be reduced with only occasional watering given to keep the plant from shriveling up.

There also needs to be a cool period where temperatures drop at night into the high 10’s to just above freezing for a couple of months. Leave the plants outside later in the fall (make sure the temperatures remain above freezing) or keep the plants inside near your coolest window. The objective is to bring the night temperatures down below 16°C for a couple of months to induce flower bud set.
