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

Peonies are a beloved staple in many gardens, renowned for their lush, large blooms and delightful fragrance. However, to ensure your peonies put on their best show come summer, it’s crucial to give them the right care in April. This month is a pivotal time for peony care, as it sets the stage for the growing season ahead. From soil preparation to pest management, each step you take now will influence the health and beauty of your blooms.
Whether you’re a seasoned gardener or new to growing peonies, this guide will walk you through ten critical tasks to perform in April. By following these steps, you’ll be well on your way to achieving a spectacular display of peonies that will be the envy of your neighborhood. Let’s dive into the essential care tips that will help your peonies thrive and dazzle this summer.
1. Start With a Ruthless Early-Spring Clean-Up Around Each Peony
Begin your peony care routine with a thorough clean-up of the area surrounding each plant. Remove any debris, fallen leaves, and old plant material, as these can harbor diseases and pests. Clear a radius of about 18 inches around each peony to ensure good air circulation and reduce the risk of fungal infections.
Ensure you also prune any dead stems from the previous year, cutting them back to ground level. This will allow the new growth to emerge unhindered and reduce the chance of disease spreading from old plant matter to new shoots.
2. Loosen and Enrich the Soil Without Disturbing Peony Crowns
Peonies thrive in well-drained, fertile soil, so it’s important to refresh the soil around them in early spring. Carefully loosen the top 2-3 inches of soil with a hand fork, taking care not to disturb the peony crowns which should be just below the surface.
Incorporate a 2-inch layer of well-rotted compost or aged manure into the loosened soil. This will provide essential nutrients that will boost growth and support the development of large, healthy blooms.
3. Feed Peonies the Right Fertilizer at the Right April Moment
Feeding your peonies with the correct fertilizer at the right time is crucial for optimal blooming. In April, apply a balanced fertilizer, such as a 10-10-10 formula, to encourage strong growth. Spread the fertilizer evenly around the base of each plant, avoiding direct contact with the stems.
For best results, apply the fertilizer just as the shoots begin to emerge, and then water thoroughly to help the nutrients reach the root zone. This will give your peonies a head start on the growing season and promote vigorous flowering.
4. Master Watering: Deep, Infrequent Soaks for Bigger Blooms
Proper watering is key to encouraging large, vibrant peony blooms. Instead of frequent shallow watering, aim for deep, infrequent soaks. Water your peonies deeply once a week, providing about 1 inch of water per session.
This approach encourages deep root growth and helps the plants withstand dry periods. Be mindful to water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases.
5. Install Sturdy Supports Now Before Stems Shoot Up
Peony blooms can be heavy, and without proper support, the stems may bend or break. Install sturdy plant supports, like peony rings or cages, around your plants in early spring before the stems grow tall.
Place the supports when the peony shoots are about 6 inches high. This ensures that the plants grow through the support structure, providing natural stability as they mature and bloom.
6. Divide, Transplant, or Rescue Struggling Peonies Carefully
April is a suitable time to divide and transplant peonies that are overcrowded or not performing well. Carefully dig up the peony clump, ensuring you don’t damage the roots, and divide it into sections with 3-5 eyes each.
Replant the divisions in a well-prepared location, ensuring the eyes are no more than 1-2 inches below the soil surface. Water thoroughly after planting to help the roots establish in their new location.
