Ideal Growing Conditions for Rex Begonia Vine
Light
This vine requires bright indirect light for fine growth. To boost colorful foliage, place the plant near an east-facing window; it will provide mild morning sun and protect the leaves from harsh afternoon light.
Soil

Water
Water Cissus discolor regularly across the growing season (spring and summer). Do not let the soil dry out entirely. Before watering, check the moisture of the soil with your fingers; if it feels dry to the touch, then it’s time to water the plant.
If you notice droopy leaves, then it indicates overwatering; in such case, do not water the plant till the topsoil turns dry.

Fertilizer
Feed your begonia with a balanced liquid fertilizer in summer and spring once every 5-7 weeks. Follow the instructions on the package, and do not fertilize the plant in winter.
Pruning
This begonia does not need pruning, though a bit of trimming every 2-3 months can keep the look tidy. As this vine is grown in hanging baskets or trellis, light pruning gives it a bushier look.
Pests and Diseases
Cissus discolor can be attacked by whiteflies; treat them by using a cotton ball dipped in alcohol. If you notice scalding or brown spots, this indicates burns caused by bright, direct sun. To prevent this, keep the plant in an area with diffused light.
