2012 Peony Bed Soil Solarization

Wow! I just came back home to find the sun had done a great job not only solarizing my soil, but also my plastic sheeting! I put down a clear plastic sheet to solarize the soil for my Intersectional Peony Bed Preparation in the middle of June. The plastic sheet I used for the intersectional peony bed was not new. It was a few years old. It held up pretty well until last week when it started to get a few tears in it, but when I came back and took a look at it yesterday, it was half gone and in shreds! So I guess the bed is officially solarized! The ground looks pretty sterile, and it has been a little over 6 weeks now since I first put the plastic sheeting down. It usually takes about 4-6 weeks to complete the soil solarization. So I guess the plastic sheeting held up just long enough! Now the planting bed should be ready for the new, good soil to go on top and get mixed in - after I have fun picking up all of the plastic bits, of course! ;-)

I also started another soil solarization project a couple weeks after the first one for a new peony seedling test bed. I used a newer plastic sheet, and this one seems to be holding up much better. As you can see the weeds and grass underneath the plastic are all dead and brown. So this bed should be ready soon too. Maybe I can get the dirt next week!

2012 New Intersectional Peony Foliage

After quite a long hot and dry spell with 90-100 degree days, it has been nice to get some rain from summer thunderstorms and a bit cooler temperatures. I'm sure my peonies have appreciated it as well. The foliage on my newly planted intersectional peonies seems to be progressing nicely. All four of them have nice green foliage now three weeks after planting them. The foliage is a mix between a tree peony's foliage and an herbaceous peony's foliage since intersectional peonies are a cross between these two types. Tree peonies have woody stems that generate new growth each year while herbaceous peonies have soft stems that grow anew and die back to the ground each year. It is recommended to cut back the intersectional peony foliage to the ground each year, but I have found in my southern climate that some of the woody stem can be left over the winter and will generate new growth and blooms the next year. See my post on 2011 Peony Experiments - Intersectional Blooms for more information and pictures.

2012 Peony Reference Site - Web Project Paeonia

So you've always wondered if the peony variety you have is labeled correctly? Or maybe you want to know the hybridizer for your peony. Or perhaps you want to know the bloom season for a peony you saw and are interested in. Well, I'll tell you what. There's this site I really like. It is the best peony reference site out there. No, it's not the Wikipedia. (Although there is some interesting information there, it definitely leaves something to be desired.) The site is Carsten Burkhardt's Web Project Paeonia. I have used this web site for years for peony identification and information. It is really an awesome resource for the peony community. I hope you find it as useful as I have. So go look up your favorite blooms. Oh, and be careful. You can get lost in there!!! :)

2012 Intersectional Peony New Growth

The new intersectional peonies I just planted a week and a half ago are growing nicely. One of them seems to be having a bit of trouble, but it is still growing. The pink growth on Peony 'Scarlet Heaven' has a bit of brown/black on the end of it. It also seems to be a bit slower growing and turning green than the other three. Here are a few pictures of some of the new growth on these intersectional peonies. I think they are happy in their partly sunny, moist spot near my deck. These peonies were originally purchased on Ebay, and they are definitely intersectional peonies. The new growth and the foliage on these is exactly the same as my other intersectional peonies, and quite different than the new growth on herbaceous peonies. Whether the cultivar names are accurate is yet to be determined, but I think they will probably be correct.

2012 Growing Weed Free Peonies

The weeds in my peonies have been greatly reduced this year, thanks to a new layer of mulch. However I have still gotten a few weeds. Most of them have either been at the edge of the peony bed or right next to the peony crown, where the layer of the mulch is the thinnest. It is not good to put a thick layer of mulch right on top of the peony crown (where the stems grow from the plant). In my climate I do not put any mulch right in the center of the peony plant. It is best to side dress the peonies with mulch to keep their small feeder roots cool and moist. A couple of weeds have surprised me this year, though, growing right from the crown hidden by the peony foliage, and were able to develop into quite large weeds. I was really surprised by this one in particular. This weed grew bigger and taller than my 5 year old peony in a couple months! Needless to say, it has now been extracted! :)
