Prevent and combat gray mold on peonies - this is how it works

The Content Of The Article:

Peonies look sick in the spring, it is usually due to a fault: gray mold. Who does not fight this immediately, must expect that his peonies go down.

Gray mold occurs especially in spring

Almost every hobby gardener has probably ever discovered gray horse on his peonies. It is a fungus that occurs mainly in the spring. Just then, when the humidity is particularly high. The fungus can then become really dangerous for the plant. And that does not just apply to peonies. If you are not careful, you will ensure that the gray horse can continue to multiply. But to make sure that it does not get that far, we'll explain to you exactly how an infestation with gray horse expresses itself, how you can prevent it and what you have to do if your peonies are affected by it.

How does a gray mold attack?

If your peonies are attacked by gray mold, you'll notice that relatively quickly. Typical signs are:

  • young leaves wither very fast
  • Wet rot on the stem bottom
  • Bud blight, where buds turn brown and / or fall off
  • Moldy lawn around the peony

Take a look at your peonies in spring. This is the only way to prevent the fungus from spreading further.

How to prevent an infestation?

To prevent a gray mold attack on your peonies, you must note some important points:

  • Watch out for a loose floor where the water does not build up.
  • It is best to use a nitrogen-poor soil.
  • Do not use manure as fertilizer.
  • Do not pour the leaves.
  • Cut the leaves back as deep as possible in the fall.
  • In the spring, remove the mulch from winter.
  • Loosen heavy soils with sand.
  • Always choose a sunny location.

How to combat gray mold?

Unfortunately, despite all the preventive measures, it can happen again and again that your peonies suffer from a gray mold attack. If you notice the first signs, then you must act quickly and cut back the affected parts until you reach the healthy area. Be sure to dispose of the diseased parts of the plant in the household waste and not in the compost. If you were to dispose of the infected parts of the plant via the compost, then the fungus would continue to reproduce with the compost and thus attack other plants.
