Title: Fertilizing Peonies?
Post by: JPB on April 25, 2010, 08:25:09 AM: I have a number of herbaceous Paeonia species growing in pots. They are showing their leaves now. How would you suggest to feed them? How often? What is the best NPK ratio?

Thanks,
Hans

A Dutch nursery man once told me that you should not fertilize paeonies (when growing in pots) in spring and summer. Instead it should be done in fall (and winter). They take up nutrients in their resting stage, not when they are growing

I wonder if this makes sense ???

Thanks! That makes sense. I had my doubts so I never listen to this man again >:(

I feed mine (if I remember) with a tomato type feed - with the balance towards the K.

That makes more sense to me - up till late summer.

Now I get my plants into the garden as soon as I can and feed them with pelleted chicken muck in early spring with good results and if I ever get the hang of it I will post some pictures so you may judge for yourself.
