Grape ivy is a perennial plant native to Central and South America. Due to its tropical origins, grape ivy is typically grown as a houseplant in most temperate regions. Grape ivy, despite its name, is not a true ivy but is a climbing member of the grape family. It can be trained to climb small objects or the tendrils can be left to hang over the sides of the container. Grape ivy requires some care to emulate its natural environment, but will thrive if given the proper attention.
Keep grape ivy plants in a location that receives about four hours of direct sunlight each day. Maintain a constant temperature of 65 to 80 degrees F during spring and summer and 55 to 70 degrees F during fall and winter.
Water grape ivy once a week during spring and summer to keep the soil consistently moist at all times. Reduce frequency during fall and winter to once every 10 days, allowing the soil to dry slightly between applications.
Mist your grape ivy plant twice a day to raise the relative humidity. Use a spray bottle filled with lukewarm water to prevent shocking the plant. Do not spray during winter when the plant is dormant.
Feed grape ivy once a month using a balanced 10-10-10 NPK fertilizer. Follow the instructions provided by the manufacturer for proper dosage. Water immediately after feeding to prevent root burn and release the nutrients into the soil.
Transplant grape ivy into a new container once every year in late winter to prevent the plant from becoming rootbound. Increase the size of the container by about 3 inches in diameter to allow plenty of room for growth. Plant in a growing medium made of two-parts potting soil and one-part perlite.
