Experts and BHG readers answer.
Thanks for writing. Without seeing your plant, I can't be sure of what's going on with it. Yellowing leaves could simply indicate plant stress from being planted. It could also indicate over watering. Or, it may be that your bleeding heart is going dormant for the summer. (Old-fashioned bleeding hearts do turn yellow and appear to die by midsummer, especially if your area has experienced warm or dry conditions. Don't worry --- this is perfectly natural and the bleeding heart comes back bigger and better the following spring.)
