Q.Bleeding Heart bush
I planted 2 bleeding heart bushes 3 years ago..one geypts a bit more sun than the other..however they both were doing great as of last summer..This season only one has come back and is blooming.. I live in RI..and last winter was not that harsh..what happened?? Also..my 2 Catmint bushes..the same age as my bleeding hearts..are only about 6 inches out of the ground..usually by now they’re about a foot and a half high and wide..what’s wrong? Ty for any input Cheryl D
Warm winters can often be harder on perennials then colder weather. Temperature fluctuations in winter can often do damage to plants that do not go into a dormancy and stay there.
Lack of snow can also leave plants unprotected.
Plants emerge at different times and will generally take off growth when soil temperatures warm sufficiently .
