There are many different species of vine that make excellent house plants. Mandevilla, bougainvillea and passion flower are beautiful flowering vines that grow well indoors. Care for these vines is quite similar to the care for other potted houseplants. The best place to display these vines is in a hanging basket. Corners and balconies are great places for them to grow unimpeded as long as they have access to adequate sunlight.
Water your vine during the growing season whenever the top third of the container dries out. Use a watering can to fill the soil with water until you see it flowing out of the drainage holes in the bottom of the container. If your vine's container sits on a drainage tray, empty it after 1/2 hour. Do not let the container sit in water. The plant may develop root rot. In fall and winter when your vine becomes dormant, allow the top half of the container to dry out before watering.
Fertilize your vine houseplant once every two weeks during the growing season (spring through fall). Use a commercial liquid houseplant fertilizer and follow the manufacturer's instructions for application rates and amounts based on your vine's size. Fertilize only once monthly during the dormant season.
Prune your vine to maintain its size. Use a pair of sharp pruning shears to cut vines that are too long. If your plant's foliage dies back during the winter (this often happens after it is brought indoors to for winter), signaling its entrance into dormancy, prune the vines back to 8 to 10 inches. This may not be necessary for all species of vines.
Provide your vine houseplant warmth. Most houseplants require temperatures between 70 and 90 degrees Fahrenheit. Some will tolerate lower night temperatures. Research your specific variety of houseplant for more specific temperature guidelines. Keep houseplants away from the drafts of air-conditioning and heat vents.
