2018 Greensand, Vitamins for Peonies?

Organic Green Sand
After answering a question from a reader about fungus in my 2018 Question Growing Peonies in the Deep South, Dealing with Fungus article, I received a comment via email from another reader suggesting that greensand might be helpful to prevent/retard fungus. I was hoping that reader would add the comment to the article, but it doesn't look like they ever did, so I just added the comment to the post myself. Anyway I decided to purchase some to see if it would help my peonies. Greensand seems to contains minerals like potassium, iron, magnesium, calcium, phosphorus, and lot of others. So maybe it is kind of like vitamins for peonies. I'm not really sure since I've never used any in my garden, but I'm curious to see what it can do. I tried to find a local source for the larger bag, but it didn't seem to be very cost effective to order it locally. So I ended up purchasing it on Amazon. Do any of my current readers have experience with Greensand? Have you ever used it on your peonies? If so what results have you seen?

  1. Greetings, I'm the one who swears by greensand on peonies. I side dress mine (all 85 or so) every few years. If we have a wet spring, I put it down to help with botrytis. I put about 2 or 3 cups if the peonies are large. Also, about a cup is added to the hole when planting new peonies. A peony that came from my Grandmother's was loaded with buds one spring. They all dried up and not a single bud opened. Spring was very wet that year. This is when I started the greensand routine. Grandmother's peony has not had botrytis since, 15 years later. I buy a large bag, 25# bag I think, from our local Carolina Fresh Farms Nursery. A few bags are kept in stock but sometimes I have to request a special order. It's about $30 and worth every bit of it. I've used greensand on a rose too but can't rave about the response it had compared to peonies. Greensand is a great organic amendment. It also helped a birds nest fern that was not happy. We couldn't exactly determine what was wrong with it but after putting about 1/4 cup of greensand, it now grows green and lush with no more brown leaves. Gardningirl, Belton SC

    1. Gardningirl,

      Thank you for your detailed comment and information. I have a large bag of Greensand on order, and I'm looking forward to receiving it so I can try out its protective properties!

  2. I've used it before, with the thought that it supplies potash and micronutrients. Others claim that it helps water retention in soils. Those selling it seem reluctant to make any sort of hard claims for it at all. That said, it's been a traditional soil amendment for years. I bought a big bag of it myself this fall, and used it in all of my planting holes.

    1. Bob,

      It's nice to hear that more people growing peonies heard of Greensand and used it on their peonies. Have you noticed any protective properties, i.e. do the plants with Greensand seem to be stronger, more resistant to disease, blight, or fungus?
