Epiphyllum pumilum, commonly referred to as an orchid cactus, thrives best when it is provided with a well-draining potting mix, ideally a carefully formulated blend designed specifically for cacti and succulents.

It prefers to be positioned in bright, indirect light in order to prevent unsightly leaf scorch, while also allowing for a few hours of gentle, dappled sunlight each day.

Watering should be moderate; it is essential to allow the top inch of soil to dry out thoroughly before rehydrating, as this captivating species is particularly sensitive to the adverse effects of overwatering.

During its vigorous growing season, which spans from spring to early autumn, it is advisable to feed the plant with a diluted, balanced fertiliser every four to six weeks to encourage robust growth and stunning flowering.

In the winter months, one should reduce watering significantly as the plant naturally enters dormancy, and it may be beneficial to consider moving it to a cooler location to effectively mimic its natural habitat.

Additionally, it is prudent to regularly check for pests and diligently trim any dead or damaged segments to maintain both the health and visual appeal of this exquisite plant.
