Grape Ivy plants require medium to bright light though new varieties such as Ellen Danica and Mandianna can live in lower light. If the stems stretch toward the light and new leaves are further apart on the stem, move your plant to a brighter location.
Water well and then allow the top 50% of the soil to dry out before watering again. Crispy leaves mean the plant in over-watered.
Fertilize every other month when a Grape Ivy is actively growing with a basic houseplant food diluted to 1/2 the recommended strength. A Grape Ivy should not be fed in the winter. Yellow leaves usually means the plant needs more food.
Grape Ivy plants can handle temperatures from 40°-90°F (4.4°-32.2°C), although growth slows above 80°F ( 26.7°C). The ideal temperature for a Grape Ivy Plant is 60°-80°F ( 15.6°-26.7°C).
