Unlike the popular shade-loving Bleeding Heart Plant, this vining plant is tropical and won't overwinter in the garden, unless you live in a tropical climate. Give it warmth, humidity and bright, indirect sunlight year-round.
Repot in spring only when it has outgrown its container. Bleeding heart blooms best when it is slightly pot-bound, so move it up to a pot only 1 size larger. Use a pot with drainage holes to prevent soggy soil.
Prune vines back in spring, when the plant is beginning new growth. Flowers grow near the tips of new stems, so you'll get more blooms this way. You can cut the vines back by as much as half, if you want, to keep the plant small.
Raise the humidity if the relative humidity drops below 50%. You can place the pot on a tray of wet pebbles. Or mist the foliage with room-temperature water every day. Raising the humidity also helps to prevent spider mites from invading. Watch for these pests, especially in winter when indoor air tends to get dry.
Give it a winter rest. This tropical bleeding heart plant is an evergreen perennial, but it may stop flowering in the fall and winter months and growth slows down. Water sparingly during this rest and stop fertilizing till spring when you see new growth on the plant.
