Rhipsalis does best with morning sun and full shade in the afternoon.
As Rhipsalis is commonly grown indoors, care must be given to the placement of the plants. They should be kept at least 50 cm away from windows that receive midday or afternoon sun. The glass in the windows can multiply the heat from the sun’s rays, causing sunburned leaves.
Keep in mind that in its native environment, Rhipsalis is accustomed to receiving light that has been filtered through dense, overhanging tree branches. Picturing this environment can help you adjust your lighting accordingly.
Regular watering is essential. Over-watering, however, can cause weak stems and rotted roots. Rhipsalis seldom needs to be watered more than once a week. Check before watering by pressing your finger into the soil to a depth of half an inch. Postpone watering if the soil is moist. You can also use a moisture meter to help you determine whether it is time to water.
