My husband decided to cut back my peonies down to stubs. He subsequently covered most of them over with soil. I can only see one bunch of stubs and the rest are covered about 7 more plants worth. Will they be ok or have I lost them?

size of pot and care for plants in it
I would suggest bulb flowers that compliment the peonies, such as miniature daffodils. It's also fine to partner some perennials with your peony, depending upon the size of your pot and the needs of the plant. Late bloomers like small chrysanthemums or yarrow will add color. Just make sure your companion plants don't take up the nutrients needed by your peony.

I bought the tree peony a few months ago and it was planted in pot soon after. It was fine until recently. In the photo you can see an aquilegia that seeded itself in the pot. I hope you can help, as I don't want to lose it. I have another tree peony planted in the garden which is about 35 years old, which hasn't had any problems.
I'm sorry, but your photo did not come through. It sounds as though your plant has a virus of some kind, but without a photo it's just a guess. Here's an article from the University of Connecticut that may help you identify the problem:

memory. I am terrified to propagate these beautiful flowers. Will I damage my growth this year if I do this? Are mine going to produce flowers after I dig them up and cut them up to share?
If done correctly, it shouldn't hurt your peonies, but it may take them a few seasons to return to their former glory. Here is how:

why my Peony not flowered this year this is the 2nd year its been in plenty green leaves but no flowers
This is typical of feeding with fertilizers high in nitrogen. Too much nitrogen, and not enough phosphorus and potassium will result in lush foliage, but no blooms.
There are many other reasons, as well, though.
