Hydrangeas are resilient plants that typically require minimal maintenance, but there’s one straightforward gardening technique that can help them continue blooming magnificently for extended periods. August often brings dry conditions with reduced rainfall, and even hosepipe restrictions in certain areas, yet hydrangeas possess delicate root systems that demand abundant moisture to thrive.
These plants are notorious for drying out quickly during extremely hot weather, and despite regular watering, hydrangeas may begin to droop, develop undersized blooms, or cease growing altogether.
Nevertheless, Skye Hamilton, a gardening expert known as the Hydrangea Queen and founder of Hamilton House Designs, has revealed that mulching is an effective method to shield hydrangeas from heat while maintaining proper hydration.

How to mulch hydrangeas in August
It’s advisable to use a natural mulch known for its ability to retain water in the soil, such as pine, cedar, bark chips, pine straw, or leaf mulch. These types of mulch will keep hydrangeas hydrated and decompose slowly to nourish the plant and provide it with more energy.
Spread a thin layer (approximately two to four inches thick) around a hydrangea plant, but avoid overdoing it or causing it to pile up.
Hydrangeas require ample moisture in August, but excessive amounts can lead to stagnant water in the soil, which may attract pests and diseases.
After applying the mulch, water the hydrangea deeply. This should help it thrive and continue producing large, fluffy flowers throughout August, rather than struggling to survive as it typically would.
