Watering peonies deeply but infrequently is the key to more beautiful blooms this summer, according to gardening expert Luke Dejahang, CEO of Crown Pavilions. He told Express.co.uk that a simple weekly watering routine can significantly enhance the plant's flowering performance.
Watering for Strong Roots and More Blooms
Mr Dejahang explains: "You should water peonies deeply but infrequently, so about once a week is perfect. Watering once a week encourages strong root growth and more blooms." This practice helps the plant develop a robust root system, leading to a more abundant and vibrant display.
Planting Depth Matters
Correct planting depth is crucial for peonies to bloom. Mr Dejahang advises: "Ensure peonies are planted at the correct depth, with the crown (where the stem meets the root) just below the soil surface, as planting too deep can prevent blooming." The crown should sit just below the soil surface to avoid inhibiting flower production.
Fertiliser and Mulching Tips
A balanced fertiliser is important, but over-fertilising can backfire. Mr Dejahang warns that too much fertiliser "can lead to leafy growth with fewer blooms, which isn't what you want." He recommends applying organic mulch around the plants to "retain moisture, suppress weeds, and regulate soil temperature."
Sunlight Requirements
Peonies thrive in full sun to partial shade. Mr Dejahang emphasises that gardeners should "ensure that they are placed in a suitable area where they can receive at least six to eight hours of sunlight daily." Adequate sunlight is essential for optimal blooming.
Deadheading for Healthier Plants
Deadheading spent flowers is a vital task. Mr Dejahang says: "You should deadhead because it helps to neaten the plant, reduce the risk of fungal infections, and promote a healthier plant ready to flower again next spring." Use clean, sharp pruning shears to cut the stem just below the spent flower, above the first set of healthy leaves.
Planning for Next Year's Blooms
For future peony success, Mr Dejahang suggests focusing on soil preparation, planting time, sunlight, and pruning. He notes: "Peonies prefer rich, well-drained soil, so you should improve the soil with compost or well-rotted manure before planting." Plant peonies in late autumn or early spring in a sunny area. In late autumn, cut back herbaceous peonies to the ground to prevent disease.
