Short Answer
The best way to get rid of fungus on peonies is to prune the affected area and dispose of the infected plant material away from the garden.
If the affected area is too large, you may need to remove the entire plant.
You can also spray the affected area with a fungicide specifically made for peonies, applying it every 7-10 days until the fungus is eliminated.
Lastly, make sure to keep the area around your peonies clean and free of debris to reduce the risk of future fungal infections.
Causes of Fungal Infection on Peonies
When it comes to caring for peonies, one of the most common issues that gardeners face is a fungal infection.
Fungal infections on peonies can be caused by a number of factors, including overwatering, high humidity, and poor air circulation.
Overwatering can create the ideal environment for fungus to grow, as can high humidity and lack of air flow.
Peonies are vulnerable to a number of fungal diseases, including powdery mildew, downy mildew, and botrytis blight, all of which can wreak havoc on the health and beauty of the plant.
To prevent fungal infections, it is important to keep the area around the peonies well-ventilated and to water the plants at the base of the stem, avoiding wetting the leaves and flowers.
Additionally, it is important to keep the surrounding area free of any dead plant material which can act as a breeding ground for fungus.
Signs of Fungal Infection on Peonies
When it comes to caring for peonies, one of the biggest threats is the fungal infection known as powdery mildew.
This fungus thrives in warm, humid environments, and can quickly spread to other plants if left untreated.
The telltale signs of powdery mildew on peonies are white, powdery spots on the leaves and stems.
These spots can also spread to the flower petals, causing them to become discolored and distorted.
In some cases, the infected petals may even fall off the plant.
In addition to these physical symptoms, the leaves may also become yellowed or wilted, and the stems may become brittle.
If you notice any of these signs on your peonies, it is important to take steps to get rid of the fungus as quickly as possible.
Removing Affected Leaves and Stems
The first step to getting rid of fungus on peonies is to remove any affected leaves or stems.
This is important as it will help reduce the spread of the fungus.
Start by inspecting the leaves and stems of the peonies for any signs of fungus.
This can include discoloration, brown spots, or even wilting or yellowing leaves.
Once youve identified the affected leaves and stems, carefully remove them from the plant.
Make sure to remove any fallen leaves or stems from the ground as well, as this can also help prevent the spread of fungus.
If the fungus has spread to other parts of the plant, it may be necessary to remove the entire plant.
However, if the fungus is only affecting a few leaves or stems, it is possible to save the plant by removing the affected parts.
Treating the Area with Fungicide
When it comes to treating your peonies for fungus, using a fungicide is the best way to ensure you get rid of the problem.
Depending on the type of fungus youre dealing with, youll want to select the appropriate fungicide for your peonies.
For example, if youre dealing with powdery mildew, youll want to choose a fungicide that contains a systemic fungicide like chlorothalonil or myclobutanil.
If youre dealing with botrytis blight, youll want to choose a fungicide with a contact fungicide like copper sulfate or sulfur.
Before using a fungicide, make sure to read the instructions to ensure youre applying it correctly and in the correct quantities.
Once you have the fungicide ready, youll want to apply it to the affected leaves and stems.
Make sure to pay special attention to the underside of the leaves, as this is where the fungus is usually located.
After applying the fungicide, youll want to make sure to rinse off any excess fungicide from the leaves so that it doesnt burn the plant.
Once youve applied the fungicide, youll want to monitor your peonies for any signs of further fungus.
If you see any new signs of fungus after applying the fungicide, youll want to re-apply the fungicide and monitor it closely.
With regular treatments, you should be able to get rid of the fungus and keep your peonies healthy and looking their best.
Watering the Peonies at the Base
Watering your peonies at the base is one of the most effective ways to get rid of fungus on them.
This helps to prevent any water splashing on the leaves, which can spread fungus and other disease-causing pathogens.
When watering your peonies, use a watering can or hose with a fine spray nozzle.
This will help to keep the water from being too forceful and splashing onto the leaves.
Its also important to water your peonies in the morning, as this will give them the most time to dry out in the sun.
This will help to reduce the chance of fungus and other diseases spreading.
Its also important to avoid over-watering your peonies, as this can lead to root rot and other issues.
Water your peonies until the soil is moist but not soggy, and avoid wetting the leaves.
You can also use a fungicide spray to help get rid of any existing fungus on your peonies.
Make sure to follow the instructions on the packaging carefully.
Providing Plenty of Light and Air Flow
When it comes to getting rid of fungus on peonies, providing plenty of light and air flow is a key factor.
Peonies are a sun-loving plant, so they need at least six hours of direct sunlight a day and good air circulation to keep the foliage dry and prevent fungal spores from settling and growing.
If you are growing your peonies in an area that doesnt get enough natural sunlight, you may want to consider investing in some artificial lighting to help get rid of the fungus.
Additionally, make sure to plant your peonies in an area that has good air circulation, like an open field or a spot that is well-ventilated.
Pruning the plants regularly can also help to increase air circulation and reduce the chance of fungal growth.
Preventing Fungal Infection on Peonies
When it comes to preventing fungal infection on peonies, the best defense is a good offense.
That means taking preventive measures to protect your plants from fungi before they become infected.
There are a few key steps that should be taken to ensure your peonies stay healthy and fungi-free.
First, make sure to give your peonies plenty of light and air flow.
This will help keep the area around them dry, which is one of the most important steps to take in preventing fungal infection on peonies.
Second, water your peonies at the base of the plant.
This will prevent moisture from splashing onto the leaves, which can spread fungi spores.
Third, avoid overcrowding your peonies.
Make sure to give them enough space so they can get the airflow and sunlight they need.

Applying a fungicide to the leaves and stems of your peonies can help prevent fungal infection and keep them looking their best.
