AlexUnder said:Do not fertilize anything that just has being transplanted for at least a week. Trees and shrubs - even longer, months. You have to make a sun cover for your tree peony at least for a few weeks. And I suggest moving it to another location, because south facing tree peony in zone 9 is sure thing to commit herbi-cide. Probably north-facing wall is a best option.

Wow , I followed the label advice and it said full sun . The weather here where I am , north east uk is infamous for a lack of sun and also cloudy/rainy a lot of the time . So I think I can rule out too much sun as the cause of damage to my peony tree.
I think it could possibly of been over watered and like you say fertilised too early.
I was mainly worried about the watering and the depth of planting. What do you think from the pictures ? Thanks !
