Set the bleeding heart vine's pot in a location that receives bright, indirect light when it's not in flower. Move it into direct sunlight when it's in bloom, placing it either indoors or outdoors after frost.
Water the vine year-round when the soil begins to feel dry near the surface. Give the plant enough water to thoroughly moisten the soil in the pot, and empty out any water that collects in the drip tray beneath the pot after watering.
Fertilize the plant every two weeks during the spring, summer and fall. Apply a water-soluble balanced houseplant fertilizer. Use the amount recommended on the fertilizer label for the pot's size.
Move outdoor plants indoors before nighttime temperatures drop below 50 degrees Fahrenheit in the fall. Cold temperatures cause the plant to go dormant, and freezing temperatures can kill the plant.
