How to Grow and Care

In a moist and cool climate, Bleeding Heart will grow in full sun, but in warmer and drier climates it requires some shade. Keep plants well watered throughout the summer, especially in warmer weather. Even then, they may be ephemeral and disappear until the fall or next spring. If you’ve recently planted your Bleeding Heart, it would be wise to mark the spot, so you don’t accidentally dig in the area while your plant is dormant. It prefer a rich, moist soil, but are not particular about soil pH. Bleeding Heart is not a heavy feeder, so when to fertilize depends on the quality of your soil. If you have rich, organic soil that is amended every year, you won’t have to feed at all.

They can be started from seed, division, cutting or seedling. It is very easy to divide Bleeding Heart plants. It should be divided after flowering, so you don’t sacrifice bloom. The fringed-leaf varieties divide nicely early in spring, as they are emerging. It can also be started by seed or stem cuttings… – See more at: How to Grow and Care for Bleeding Heart.
