Methods For Removing White Mold From Peony?

To get rid of mold on peony plants, follow these steps:

1. Prune and clean affected foliage or flowers.
2. Improve air circulation around your plants to prevent mold growth.
3. Proper watering techniques and avoid overhead watering to keep the foliage wet.
4. Avoid powdery mildew, which is a fungal disease that appears between late June and September.
5. Apply fungicides or home remedies promptly and remove affected areas.

To combat powdery mildew, change the micro-climate around your peonies by spacing plants properly and avoiding overhead watering. Ensure good air circulation by spacing plants properly and avoiding overhead watering.

If your peonies are done growing, prune them and remove any infected material. Wear disposable gloves and sterilize cutting utensils after. Try using neem oil, horticultural oil, or sulfur-based fungicides as more organic solutions.

Fungicides have limited effectiveness against powdery mildew, but basic copper sulfate or Mancozeb can be applied early in the season when the disease is present. Common home chemical treatments include sulfur or a combination of potassium bicarbonate + Bacillus subtilis. Neem oil is also a common solution.

To reduce the risk of infection, grow peonies in full sun with good air circulation. Remove infected plant debris in fall to further reduce the risk of infection. Once your peonies are infected, there is no spray to cure them, so prevention is important. Selecting resistant cultivars along with proper care is crucial for preventing mold growth.
