Croatian Gardeners Advised: Mulch Hydrangeas by End of May for Bountiful Blooms

For gardeners in Croatia dreaming of lush, vibrant hydrangeas, Večernji List shares expert advice that could make all the difference this season. According to horticultural specialists, a key task to ensure these popular shrubs produce their most spectacular blooms involves a simple yet crucial step: mulching, ideally completed by the end of May.

If you notice that the soil is drying out quickly, add compost to retain moisture.

Hydrangeas are entering a period of rapid growth and flowering, and timely mulching is presented as the secret to sustained, abundant blossoms. Experts cited by Homes & Gardens and reported by Večernji List emphasize that skipping this step in May could hinder the plant's development. Hydrangeas thrive in moist soil, and a generous layer of mulch significantly slows down soil drying, creating the optimal conditions for growth.

Lorraine Ballato, an author specializing in hydrangeas, advises adding compost if the soil dries out quickly, but reiterates that mulching is paramount. She recommends a layer of 5 to 10 centimeters of mulch to protect the plant's roots. The choice of mulch is also important; leaf compost, bark, or pine needles are suggested. Interestingly, these materials can also help achieve the coveted intense blue color in hydrangea flowers by lowering the soil's pH level.
