tree peony wont bloom

[dr-solo]

I have 4 peonies in a south facing raised bed. 2 herbaceous, 2 tree peonies. All grow and bloom vigorously except 1 tree peony. I think it bloomed once in 2005. Then one branch was hanging down so low I cut it off. It hasnt bloomed since then. I also set my figs to the east and it gets some shade in the morning, but the azalea to the east blooms just fine. I dont over fertilize or even over water it. So what might be the problem? It really is large and robust otherwise. Ingrid

Got any tiny spider mite sized red dots in the foliage? Easier to see early on. I had to use a systemic to rid the problem. Worked but...Nasty stuff now residing in a decaying plastic container. Peonies are now happy and my search for upward facing blooms goes on.

Lime, lots of lime.
