Got peonies? 10 critical things you must do this April to get showstopping blooms by summer

7. Pinch, Disbud, and Thin for Fewer but Showstopping Flowers
For larger, showstopping blooms, consider disbudding your peonies. This involves removing some of the side buds while they are still small, leaving only the terminal bud on each stem.
This method focuses the plant’s energy on fewer blooms, resulting in larger flowers. Be sure to use clean, sharp tools to avoid damaging the plant and promoting disease.
8. Shield New Growth From Late Frosts and Wild Spring Weather
In April, weather can be unpredictable, and late frosts can damage tender peony shoots. Protect your plants by covering them with a light row cover or a layer of straw when frost is forecast.
Be cautious not to leave covers on for extended periods, as this can trap moisture and lead to fungal issues. Remove covers promptly once the danger of frost has passed to allow sunlight and air circulation.
9. Get Ahead of Disease and Pests With Smart Preventive Care
Preventive measures are key to keeping peonies healthy. Apply a fungicide treatment early in the season to protect against common diseases like botrytis blight. Choose a product labeled for use on peonies and follow the application instructions carefully.
Regularly inspect your plants for signs of pests, such as aphids or thrips, and take action if necessary. Introduce beneficial insects or use insecticidal soap to keep pest populations in check without harming the environment.
10. Use Mulch Strategically to Lock In Moisture and Stop Weeds
Applying mulch around your peonies offers multiple benefits. A 2-3 inch layer of organic mulch, such as shredded bark or straw, helps retain soil moisture, suppress weeds, and regulate soil temperature.
Ensure that the mulch is kept a few inches away from the stems to prevent rot. As the mulch breaks down over time, it will also enrich the soil, providing additional nutrients for your peonies.
