2014 Questions - Peony Soil Solarization & Weed Control

I received this question from Taherra in zone 7:
"I came across your blog in researching solarization as a method to create new planting beds. Your solarization project for your peony beds was in 2012 and I was curious as to the weed and grass control in that area. Any info/tips would be greatly appreciated."

For me this was an extremely successful project. The weed and grass control has been excellent. The only weeds that grow in this area are generally near the edges of the bed, where weed seeds have fallen from weeds growing outside the solarized bed. I have kept it weed free by mulching the soil with wood chips. I also curb any new weed growth by hand weeding the interior of the bed and spraying a weed killer around the exterior edge of the bed. The steps I took to create my solarized peony bed are outlined in the following posts:
1. 2012 Intersectional Peony Bed Preparation
2. 2012 Peony Bed Soil Solarization
3. 2012 New Dirt for New Peony Beds
4. 2012 Soil for New Peony Beds
5. 2012 Intersectional Peony Garden Planting

Soil Solariztion Tips:

1. The fewer sheets of plastic the better. Try to get your plastic sheet in one whole piece that will cover the area of your bed. This will keep the area hotter with less air escaping between the plastic sheeting.
2. The more weights the better. The bricks I used around the edge of the plastic sheeting not only keep the plastic sheet in place, but also trap the heat underneath. I actually added more bricks to the edges of my plastic sheet after a couple weeks to keep the hot air in.
3. Keep the sheet in place. Don't be tempted to remove the plastic sheeting early. Keep it in place the recommended 6 to 8 weeks to make sure the job is completely done. If you have extra time, then leave it on a little longer. It won't hurt and can only help!

2014 Heat Tolerant Peonies for Southern Gardens

The month of July is great! Fireworks, American spirit, and don't forget the blistering heat! The peonies have long since finished here in the South. Their blooms are but a distant memory captured only by the photographs I've taken and the camera in my mind's eye. So with the heat of July, I thought an appropriate topic would be heat tolerant peonies for Southern gardens. If you were disappointed with your peony display this year and are looking for hints on how to improve your peony garden for next year or maybe you just want to add more lovely blossoms to accompany the gems you already grow, then now is the perfect time to start thinking about building a better peony garden. Fall is the perfect time to plant peonies, and if you haven't gotten your 2014 peony order in yet, now is the time to do it! So I've done a little research, and here are some great sites to check out for tips on growing peonies in the South...

Also if you are looking for specific peony varieties that will grow well in the South, you will definitely want to check out our list of Southern Peony Best Performers. These are peonies that grow and blossom well here in the heat of the South. I select the best performer each week of the peony growing season here in our hot and humid weather. These peonies will definitely survive the heat and return year after year!

2014 Peony 'Paul M. Wild' Best Performer - Week 7

As I look around my garden, I find the last peony blooming its bright pink heart out, Peony 'Paul M. Wild'. He's like the last man standing in the wild west. The man, the peony that can outlast all others. Sure he's a little rough and tumble around the edges, his petals browning a little on the edges, but by this time of year whose edges aren't? Peony 'Paul M. Wild' is a dark pink, very full double peony and consistently a very late bloomer. He holds his guns until the end, and provided the weather hasn't defeated everyone by now, he lets them loose in an explosion of bright, end of the season color. So if you're looking for a peony that will not only add some additional time to your peony bloom season, but also add some bang to it, then Peony 'Paul M. Wild' is definitely your man!

2014 Intersectional Peony Fungal Diseases


Intersectional Peony 'Misaka'
with Phytophthora? Fungal Disease

This year I noticed the same three intersectional peonies had the same fungal diseases they did last year. I was wondering if there was anything I could do to prevent it next year or if I need to get rid of the entire plant. None of my other intersectional peonies have any diseases to speak of. However these 3 specimens were apparently sold to me with the diseases, unfortunately. The intersectional peony pictured above, Peony 'Misaka', I purchased as a potted plant from a local nursery, and it did seem a little suspect when I bought it. I'm wondering if it has Phytophthora blight because of the curled, deformed leaves. Plus I've seen plenty of Botrytis blight on my herbaceous peonies before, and this seems to be a little different. I guess I know better now than to buy anything that seems a little iffy. However the two intersectional peonies pictured below were both purchased as roots from two different reputable growers. I had never seen any incidence of Peony Blotch in my garden until I got these two intersectional peonies with the disease, Peony 'Layfayette Escadrille' and Peony 'Scarlet Heaven'. That is interesting because both of those 2 intersectionals are red in color. I wonder if they are somehow related and more susceptible to the Peony Blotch fungus.

When researching these diseases on Google, I found this awesome page on Peony Problems on the Missouri Botanical Garden web site. It seems like the only thing I can try to get rid of these fungal diseases is to make sure to cut these peonies all the way back to the ground in the fall. I will try that and hope it works, since I usually don't cut my intersectional peonies all the way back. I try to cut them back only to their lowest surviving bud, which usually keeps a bit of the stem there. I hope it does work, since the MOBOT web page seems to suggest removing and discarding the plant and its soil entirely as the only other alternative. I hope it doesn't come to that... :-(
