The most critical error is improper watering. It's essential to strike the right balance because hydrangeas thrive on moisture but will suffer in waterlogged conditions, reports .

"The right balance will keep the roots cool and hydrated, giving you the best possible blooms and glossy foliage above the soil," the expert advised.

She cautioned: "Avoid watering too often, especially when drainage is not good, as this can quickly lead to root rot. If conditions don't improve, the entire root system will become mushy and the plant will die."

For those looking to rectify this issue, it's recommended to wait until the soil is somewhat dry before watering again, and to consider recent rainfall in the area.

Simultaneously, it's crucial not to delay watering hydrangeas, as insufficient hydration and erratic watering "will lead to stress, limiting new growth and preventing flowering".

The specialist highlighted that water is a "fundamental element" in photosynthesis and without adequate moisture, "hydrangeas cannot grow".

The method by which gardeners water their hydrangeas can also impact the plant's development. It's advisable to steer clear of overhead watering where feasible, directing the flow of water solely towards the soil.

Maddison remarked: "This keeps the leaves dry and prevents the proliferation and spread of damaging fungal diseases."
