Hi, friends! Today I will tell you what I do with peonies after they bloom.

✂️Deadhead Spent Flowers
After blooming, peonies begin to form seeds, a process that uses a lot of the plant’s stored energy and nutrients. By removing faded blooms, you help the plant conserve these resources, which encourages stronger and more abundant flowering the following year.
Cut the flowers as soon as they start to wilt—don’t leave them on the plant for more than a week.
When pruning, make your cut about one inch below the flower, just above the first set of leaves. This removes the flower and a short section of the stem it’s attached to.
Avoid trimming the main stems or leaves at this stage. The foliage remains vital, as it continues to produce and store energy needed for next year’s growth and blooming.
🌱Mulching
Applying mulch around peonies greatly improves their overall health and growth. Mulch helps retain soil moisture, which is especially important for peonies, allowing them to grow larger and produce more blooms.
Compost is one of the best mulching materials to use. As an organic product made from plant matter, it not only locks in moisture and regulates soil temperature but also enriches the soil with valuable nutrients.
Spread a layer of mulch about one to two inches thick. Avoid making it too deep, as thicker layers can block oxygen from reaching the soil and cause problems for the roots.
When applying, keep the mulch slightly away from the base of the plant. Leave about a one-inch gap between the mulch and the stems to prevent rot and fungal issues.
🧪Fertilizing
To help peonies recover after blooming and build strength for the next season, proper fertilization is essential.
After removing the faded flowers, feed the plant with a liquid fertilizer to replenish nutrients. In most cases, one application is enough.
Avoid fertilizing after August, as doing so can trigger new growth that won’t have time to harden before frost, leaving it vulnerable to cold damage.
When choosing a fertilizer, select a balanced, all-purpose product from a trusted brand. High-quality fertilizers make a noticeable difference in the long-term health and vigor of your peonies.
🌡️Disease Control
After flowering, peonies may become more vulnerable to diseases such as powdery mildew, especially as the plants recover and are in a weaker state. Powdery mildew is a common problem that can quickly spread if not addressed early.
If left untreated, it can seriously harm your peonies, leading to stunted growth and slower recovery the following season.
To protect your plants, apply a fungicide specifically designed to control powdery mildew. Regular preventive spraying helps keep your peonies healthy and ensures strong growth in the next year.
💧Watering
Keeping the soil consistently moist is vital for healthy peonies. In general, they need watering every 7 to 10 days, particularly during dry periods without rain.
Regularly check the soil’s moisture level, and water the plant when the top 2 inches of soil feel dry. Usually, 1 to 2 gallons of water per plant is enough, but during long dry spells, you may need to increase the amount slightly.
When watering, focus on the base of the plant rather than the foliage. Avoid wetting the leaves, as damp conditions can promote fungal diseases and other issues.

Can you plant the seed pods?
Hi Valerie. Just take the seeds out of the pods and plant them in the soil.
Powdery Mildew has taken over my peony plant. I noticed it starting before the plant even bloomed. I use neem oil on the plants but that is not taking care of it. What should I do with this? It’s just the middle of July! Thank you!
Hi! I would suggest that you spray your peony with a copper fungicide and repeat this after 2-3 weeks. Usually copper fungicide works well in contrast to neem oil.
