I noticed problems with my 2 new peonies planted last fall. They grew normally but yesterday I found that leaves of Diana Parks became dark (almost black). I trimmed them but left some on stems (don't want to cut half of the growth).

Something worse happened to Do Tell, yesterday it was still fine and today I found that both stems are wilted. I straightened them up but doubt it will help.

Please advise what are these problems, appreciate all information. Thank You!

Sorry Anya, that you are having problems.
I had the partially black leaves on some of my peonies, and just cut the leaves off.

Hard to say what is going on with your Do Tell. Sometimes when the sun fully comes out, Fall planted peonies don't have an established root system and will wilt like that. The best thing to do is to put a lawn chair over it until it strengthens up.

Sigh. It is always something!!

Wondering if its getting enough moisture with the landscape cloth surrounding it.

Or do you have criters like voles which will burrow under and bite young roots?

The soil is almost wet. There is still a lot of moisture after the snow melt so I don't plan to water any peonies so far. I am afraid of putting too much moister since had a problem of rotting roots.

Thanks!

Yes, we have voles but both cats take care of this issue very good! I don't know if voles can be a problem, peony roots look like unattractive to all critters. I saw tons of voles in our Botanical garden, they escape one's view running into holes in the landscape fabric by the peony roots and the peonies there just thrive!

Thank you!

The low parts of the stems are already almost dry, I tied them up to a small pole. the leaves are still green but I am not very optimistic...

Thank you!

Over fertilized maybe? Or too hot of roots from black cloth use? Couple of ideas. I do trim things back if I see that. No use peony putting energy into failed or dying stems.

I am with Rj and Tracey. I believe the problem is somehow related to the landscaping cloth, which cannot be good for the plants. I cannot see how micro-climate and microbial activity can be healthy below that thing. I would remove it immediately and mulch with fresh soil.

It could be that you planted it too late and roots did not developed before winter and soil freeze. I guess in this case it could not maintain sufficient water and nutrient needs of the plant - something similar to bud blast, but on the whole plant level. I did happen to one of my peonies (stems started to rot at about an inch above the soil level ) and at the end I had to cut all leaves, treat soil with fungicide and change top soil above root crown. To my surprise new leaves appeared a few weeks later, but on smaller scale. It looks healthy this spring, but no buds.

I have not fertilized it yet, put some fertilizer when planting last fall, maybe I put more than to others or this variety does not hold it. Yes, the last 3 days were pretty hot here (75F), today is 52F. Usually black fabric is a good thing here. Jasmin, it is used here commonly for any gardening and peony growing in particular (at the Botanical Garden also), not my invention Smiling I will trim the leaves when it stops pouring.

Thank You!

I checked - planted it among the first last fall (September 17, the last was planted on October 3). I panted 20 roots last fall and 2 are still in the ground, 2 have the problems I described. I totally agree that the peonies did not have enough time to develop small roots but I cannot plant earlier because of nurseries, maybe a little earlier if I planned better last fall. I will do what you suggested.

Thank You!

Black fabric, even black poly, is commonly used here to prevent weeds. Although the poly is usually between rows of plants, not directly over. The fabric allows moisture to penetrate but inhibits weeks. Actually helps to hold the moisture by reducing evaporation.

With my chickweed crop I should poly my entire yard. Rolling on the floor laughing

I also have had the little black leaves. Generally not a good sign. Can't remember what happened to the plant as that was some time ago.

Thanks, Mary. Yes, I decided to use this thick black fabric to both block weeds and retain moisture, so far I like it. Anyway there are almost none nutrients in the soil Hilarious! we have to add them manually. I saw both ways: fabric between the rows of peonies and right above them like in the Bot. Garden. It works though adding fertilizer is a little harder.

I am glad your Bride's Dream has multiplied! Thumbs up
