West Yorkshire, United Kingdom
I planted a tree peony last year. This year it was coming on, although slowly, but when I looked recently the one flower bud had died and some leaves have gone brown and the stems are also being affected. Maybe the frost got the bud, but the affected leaves are more protected in the middle of the plant. Peony fungal diseases are described as grey, not brown, so I've no idea what's happening to it. Anyone know what is wrong?
