I also have a large row of peonies where large trees have grown over them so they don't get any sun. I am in the process of making a new bed for them out in the front yard. Hope that helps them!

Another thing about peonies...If some of these started from seed from the original plants, the flowers on them will not be pretty and big until they have been growing for 3-4 years, So it could be that some of them that had buds were seedlings that weren't old enough to produce many or big flowers, and usually they produce a single instead of double bloom until they reach a certain age. So if you really think they are over crowded then Fall is the best time to thin them out a bit. Also they just may need some care in order to bloom properly.

I love my peonies. The blooms don't last very long a week to two weeks is probably the max you can expect. Many bloom types will shatter due to rain or wind which is why they need to be planted somewhere they are protected. Mine are under a maple tree and like it just fine there.

It's very true about the planting depth needing to be as close to 1 inch as you can manage. Which is also why mulching them is not recommended. I've also ran across information that recommends alfalfa pellets as a good food for them. So I scratch it into the soil around the drip line for them. They are the same pellets you find in rabbit food although I did buy mine at a on-line garden center.

Understand that peonies don't like to be disturbed, so if you move them you may have to wait 3 to 8 years for them to bloom again depending on the variety.

I would definitely move the trumpet vine. Peonies last from 75 to 125 years and some types run into the 100.00 of dollars to buy so I wouldn't risk loosing them to an invasive vine.

Mind if I jump in and ask a question? My peony leaves have a white dusty look to them all of a sudden. I've never noticed that before. Is it a problem? Some of them also have brown spots on the underside.

Thanks

First of all mark where they are. It's suprising what I forget between one day and the next. Second wait until they die back. At that time they should be ready to be divided. You want to use a sterile very sharp knife. And when you replant leave at least 2 feet between them. Again you want to make sure each piece has between 3 and 5 eyes on it.

Next about the planting hole. Peonies only want to be about an inch below ground. But you need to dig the hole deeper than that and then add bone meal, blood meal or alfalfa pellets to the hole and mix it in with the dirt. Then build the little hump in the middle of the hole place the division on top of it and then fill in the hole and water and then add more dirt until it is level.
