In the fall devide the plant, and look up how deep the plants should be. If it's too deep it won't flower. In spring, use lime and fertilizer. Ues stakes to hold plants upright Good luck

I know this will sound odd, but pesticide was the problem for my mom's peonies. When she stopped using pesticides and the ants ran all over the peonies they bloomed like crazy. Do not know why, maybe they pollinated it, but that is what worked for her. ;)

They may be planted too deep. Also give them some bone meal in the Fall - work into soil around base of plant. I do this every year and always have gorgeous peonies.

They probably need to be divided, needs to be done every so many years. Same for daffodils.

A warning - DO NOT BRING THEM IN YOUR HOUSE. Ants, ants, ants all over the place.

Are they planted too deeply, maybe? Peonies like to be just under the soil, as they need the sun on their roots to bloom properly.

They are very perticular on how deep they are planted. I have 1 bush that has been her for 28 plus years and blooms are just beautiful. I will put feed on them and that is all I do. In the fall I will cut back to the ground.

I've heard that also and a friend of mine had a few plants which bloomed beautifully... and they were so full of gorgeous color..... and also were full of ants !!!!!!!!!

I planted three, got one peony on one bush the 2nd year, this year, the third, they are looking great, I think I might get 10+ off all three.

The number one reason for bloomless 'pineys' is planting too deeply. And, yes, WOOD ashes are great side dressing for pineys and lilacs, too.

From what I know and have been taught, your peonies are planted too deep.

As far as dividing, do it in the fall, get as much of the root ball as possible, divide that so each division has 4-6 'eye's', and replant in a prepared hole with plenty of compost/manure/soil mixed in well.

Mine are in full sun facing south and my fushia colored one bloomed like crazy this year. This was a division from the one that had been planted in our back yard over 50 years ago and my DH accidentally mowed over. It took about three years before it 'woke' up and bloomed.
Here is last years pic of it. This year, it had twice as many blooms and was about 6 inches taller. I always deadhead after blooming time and then in the fall, I cut back the whole plant to about 5 - 6". I have never fertilized and never water it. I will be dividing it this fall. I have other areas I want to try it in.
Sure do love that yellow one. Wow! What a beauty. Want to trade divisions? Let me know.

Ok. A & D Peonies says that you shouldn't cut off the blooms! It will actually cause the plant to not do as well. That sounds backwards from other plants, but they are the experts. Also, not too deep. Ants just love the sweet secretions, they are not needed for the plant to bloom properly. Just a myth.

Here is something else I just thought of. If there was a peony planted in that spot before, she needs to remove all the soil from the area and replace it with fresh. Peonies and roses release a chemical into the soil to inhibit the growth of competing peonies and roses! Cool, huh?
