Hydrangeas, known for their stunning flower heads, are surprisingly delicate and prone to drying out in hot weather. Their broad leaves lose moisture rapidly under the sun, making them one of the most water-hungry plants in any garden. As summer approaches, gardeners are urged to keep a close watch on these blooms to prevent wilting, browning, and stunted growth.
Gardener Julia Marcum from Chris Loves Julia has shared a simple mulching method to keep hydrangeas hydrated without constant watering. 'Not only does a fresh layer of mulch give the yard that crisp, high-contrast look we love against the green leaves, but it's also the secret to keeping hydrangeas happy,' she said. 'Mulching helps retain moisture in the soil and regulates the temperature around the roots during those hot summers.'
Mulching involves laying organic material such as pine needles, straw, shredded leaves, or grass clippings around the base of the plant. This helps the soil retain moisture, keeps roots cool, and reduces the need for frequent watering. As mulch breaks down, it releases nutrients into the soil, giving hydrangeas a boost during their flowering season.
Gardeners should spread a two to three-inch layer of mulch around the hydrangea, avoiding contact with the foliage to prevent rot or pests. Once applied, monitor the plant every few days and water thoroughly. Avoid using fertiliser in high temperatures, as its salts can deplete soil moisture and stress the roots.
