Hi Fellow Gardeners,
Have a couple of peonies one is ten years old and the other five years old.
The older one flowered after a couple of years as expected, but for the last
two years no flowers at all. The young one still hasn't flowered. I
realise peonies may not flower for up to two years, but don't know why they
stopped, or in the case of the younger why it didn't flower at all.

The are in a sunny - ish location and it gets (probably) cold enough in the
winter. Not much frost though. Every spring lots of nice good shoots. I
read that they don't need dividing for ten to fifteen years so don't think
this is the problem
What to do?. Any ideas? Not enough sun??? Could it be simply not enough
water?
Thanks for suggestions.
Diana
