The tree peonies (new this year) appear to have gone dormant?
It has been a hot and dry year here. We have had a couple of nights around 7ºC or 40 ºF. This seems too early for dormancy ?

All of mine have gone dormant already. They also bloomed early than normal this spring. Just this year's cycle.

This year the tree peonies from Costco have gone dormant already in spite of digilent watering. (very warm here)
Others from Lowe's and tire store are still growing nicely.
The roots on the former were not that great !
The roots on the others were larger.
All have the same Brand and source ?
Not doing the Costco ones again !
Paying extra $5 gives better plant!

Caroline, what do you mean by dormant? all leaves are turning brown, etc? I have a haskap problem - one is totally brown and appears dead...TP. on the other hand, is not direct sun and looks healthy and green.
I want to move my haskap from full scorching sun to different location, but do you think it is good idea at the moment? or should I wait for October?

These leaves are just going dry and wrinkled and the stems are drooping.
I think;- maybe shade the Haskap for now with a large paper garbage bag cut out on the north side ? Move when cooler weather?
I am keeping several recently acquired peonies in their pots until cooler weather comes. It is necessary to keep them moist when they are in the ground before they form feeder roots.
Earlier this spring, I planted several new roots and they are having a rough time, with watering every day necessary.
I also did one potted Dancing Butterflies in the ground, and it needs water almost every day.
Recently, I acquired other perennials and am keeping them for cooler weather also.

For the last three years, I have purchased the Costco Japanese Tree Peony collection, and have never had a problem. Do they bloom the first year-never? If they have dried up, they must be dead because my Tree peonies only dry up after heavy frost or snow here. I have a bunch of them, yellow, pink/red, red and on and on. Just love them! I don't do anything to them, no fertilizer, nothing. Planting depth may be an issue as with "regular" Peonies, but that would not lead to drying up, just lack of blooms. Sorry to hear of your results! I have no allegiance to Costco, buy them from whatever source you can. Years ago, I bought them from Can.Tire, for $9.00 in a little cardboard box, all Japanese! Cheers!

I too bought one TP ( yatchotsubaki ) from Lowes for around 10 dollars in spring of 2017 and it is doing just fine with 2 flowers this year ( unfortunately not sure whether it was true or not as I was away ). I kept it in a much bigger pot after I changed pretty much all soil and mulch, added a lot of soil, put it the soil as deep as possible and kept in the shade and well watered for all summer. Planted in the fall of 2017.

Hope they will come back for you next year, Caroline. I believe they will survive because they are very resilient. The only time that I actually kill a tree peony is when I overwatered and the root and crown rotted.
