Why are my hydrangea flowers green? I asked an expert

Hydrangeas are known for their vibrant, colorful flowers, but sometimes they can turn an unexpected shade of green. Gardening expert Paul Parker from J. Parker's explains that this natural aging process is part of the life cycle of hydrangea blooms. While the timing and intensity of this color change can vary depending on the specific variety and growing conditions, it is generally harmless and adds interest to autumn arrangements.

However, several routine factors can affect the growth and flowering performance of hydrangeas. Extreme weather conditions and improper pruning can lead to poor blooming. Parker emphasizes that proper care is essential for these shrubs to perform optimally. To protect hydrangeas during winter months, it is recommended to apply a layer of organic mulch around the base of the plant.

This helps retain moisture, provides protection against cold temperatures, and suppresses weed growth. Organic mulches include composted bark, wood chips, straw, or leaves, which decompose over time, adding nutrients to the soil.

Additionally, it is important to protect plants from heavy snowfall. After a period of heavy snow, gently brush excess snow from branches using a broom to minimize the risk of damage caused by its weight, especially during prolonged periods of harsh winter weather. Other care tips include removing damaged or diseased stems to maintain plant health throughout the season.

Leaving faded flower heads intact through winter can also be beneficial, as it helps protect developing buds for spring and adds seasonal texture to the garden.
