Bleeding heart flower problems

First though WO is flowers wilting under hot sun. Is your plant in the open and subjected to the heat of the sun, esp over the past week? Although a woodland plant I can grow them here in the open but they are sheltered from the sun by taller plants.....???
Slugs? Right now masses of those small (whatever type they are!) slugs are busy overnight feasting on all sorts of goodies without leaving slime trails. Maybe nip out with a torch tonight WO and see if they are there

 

Did the emerging shoots get caught in the last cold spell?

 

I love dicentra plants Woo. They do like a bit of shade. I brought mine here from my old north facing garden. They were in a pot and got plonked on a south facing patio when we moved in here. They weren't very happy at all. Some shade may make a difference to yours.

 

probably the sun. all of mine are tucked under larger shrubs that case shadows over them. Last year happen on one that has the yellow /green leaves and white flowers, a pop of bright color in my shade garden. this will be its 3 year so expecting wonderments.

 

As you may, (or not), recall, I adore the bleeding heart plant - most especially "Alba" - only today I was astonished at how well my own plant is thriving! My plant (a gift from a friend ) I noticed today has shot up - to the point of near full flowering! It is in "deep shade" (defined as less than 3 hours of sunshine). This from nothing but a hint one week ago - the heat is certainly making it bold; just not direct sunlight!

However, when it comes to "flowers" - my daffs have faired less well ... the reason being snails/slugs Might this be the reason for your lack of flowers?

Dicentra adores a shady position (as do slugs/snails) and, at this time of year, when fresh food is on the offing, they will grab any, and all, on offer! (Naughty molluscs ).

Have you checked for vine weevil? In my experience, it is not common, but that doesn't mean it cannot happen. Have you given it a good mulch of organic matter? Being a woodland plant it might benefit from some leaf mould if you have it?

At the end of the day: give it a good "Woo Talking To!" and remind it to pull its socks up ...
