Light: Grow ivy in medium light for best results. It does tolerate low light, but ivy won't grow as well or last as long in dim spots. Ivy can take bright light indoors, as well, and even a bit of direct sun on its foliage. In general, ivy varieties that have white variegation on their leaves are more susceptible to damage from too much sun.
Water: Water ivy when the top inch or so of the potting mix dries out. If you miss a watering or two and your ivy wilts, don't worry -- it should recover after you give it a splash of water. Take care not to overwater ivy. It's best to keep this houseplant a little too dry than a little too wet.
Temperatures: A variegated ivy tolerates most indoor temperatures, but room temperature of 50 to 70 degrees Fahrenheit during the day and 5 to 10 F lower at night is best.
