Actually, the bleeding heart is a fairly robust plant that is not easily attacked by pests or pathogens. Only when the mountain forest plant is too sunny is it weakened and primarily infested with plant lice. Towards the end of the flowering period and beyond, the leaves of the perennial often turn an unsightly yellow. What's behind it?
Yellow leaves usually indicate a nutrient deficiency
Yellow leaves are normal after flowering
Normally, yellow leaves on many garden plants mean that they are missing something - usually nutrients - or they are infested with pests. However, in Bleeding Heart yellowing leaves are perfectly normal and not a sign of deficiency or disease - provided the yellowing does not appear until late in flowering and/or shortly after. In this way, the perennial prepares itself for the winter and will withdraw to its underground rhizome within a short time.
tips
However, if the yellow leaves appear well before the usual time, voles could be behind it. The voracious rodents like to eat the fleshy rhizomes, so that they gradually die.
