Grape ivy, also known as Cissus rhombifolia and closely related to the grape family, derives its common name from its ivy-like leaves and climbing growth habit. Prized for its attractive foliage and ease of care as a houseplant, fast-growing grape ivy thrives in typical household conditions. Native to Central and South America, the plant cannot survive cold temperatures, which makes it ideal for indoor growing in mild climates. Allow grape ivy plenty of room to trail by planting in a hanging basket or placing its container atop a high bookshelf or dresser.
Keep grape ivy plants in a location that receives four to six hours of indirect sunlight each day. Maintain a temperature of 60 to 80 degrees Fahrenheit during the day and 50 to 55 degrees Fahrenheit at night for optimal growth.
Mist the plant twice each day to increase relative humidity. Use a spray bottle filled with tepid water to minimize shock and the risk of disease. Increase the frequency of misting to three times per day during winter, when the air is especially dry.
Water grape ivy plants just before the soil has dried out completely, about once every 10 days. Reduce watering frequency to once every two weeks during winter, when the plant is dormant and needs less water.
Fertilize about four times per year, once in early spring, early summer, late summer and mid-fall. Use a balanced 10-10-10 NPK fertilizer at the rate recommended by the manufacturer for best results. Water thoroughly after application to prevent root burn.
Re-pot grape ivy during spring every year to provide fresh soil and plenty of room for growth. Increase the size of the container by about 2 inches each time. Use a growing medium made of two parts potting soil and one part organic compost to provide adequate fertility.
