Hydrangea care tips

Hydrangea is a highly valued cut flower known for its large flower heads, rich colours, and strong visual impact. The flower is widely used in premium bouquets, wedding work, event decoration, and seasonal floral arrangements. Due to its impressive bloom size and versatility, Hydrangea remains an important product throughout the floriculture supply chain.

Hydrangeas are available in a wide range of colours including white, blue, pink, purple, green, and antique shades. Two main commercial types are commonly distinguished: the fresh spring and summer Hydrangeas with vibrant colours, and the classic or antique varieties available later in the season, which develop papery textures and vintage colour tones. These characteristics make Hydrangea suitable for both fresh and dried floral applications.

Originally native to Asia and the Americas, Hydrangeas are now cultivated worldwide in both greenhouse and outdoor production systems. Due to their large flower surface and high transpiration rate, Hydrangeas require careful post-harvest management. Proper hydration, conditioning, and hygiene are essential to maintain flower firmness, prevent wilting, and ensure long vase life across the chain.

🔎 Challenges: Wilting, dehydration and water uptake

One of the biggest post-harvest challenges in Hydrangea is its extremely high water demand. Due to the large flower surface and thin petals, Hydrangeas lose moisture rapidly through transpiration. When water uptake is insufficient, flowers can wilt quickly and lose their decorative value.

Another common issue is poor hydration caused by blocked or woody stems. Especially in outdoor-grown Hydrangeas, stem ends can become hard and restrict water uptake. Recutting stems is therefore essential to restore hydration and flower firmness.

Hydrangeas are also sensitive to bacterial contamination in buckets and vases. Poor water quality reduces uptake efficiency and accelerates wilting. In addition, white Hydrangea varieties may develop unwanted blue discoloration when exposed to products containing aluminium sulphate, which can be problematic for wedding and event work.

Without proper hydration management and clean handling practices, these challenges can significantly reduce vase life, flower quality, and customer satisfaction. A structured conditioning approach throughout the supply chain is therefore essential.
