As UK temperatures remain high, cut flower bouquets are wilting faster than usual. A straightforward, free trick can revive drooping blooms in just 30 minutes and extend their lifespan.
The 30-minute revival trick
Sandra Varley, flower expert at Flying Flowers, shared tips for helping floral bouquets survive the heat. She explains: "When temperatures climb, cut flowers lose moisture far faster, so even a freshly bought bouquet can start to wilt within a couple of days if it's not looked after properly."
If blooms look lacklustre, Varley recommends: "Remove the stems from the vase and submerge the flower heads in cold water for 30 minutes. Afterwards, re-cut the stems at an angle before placing them back in fresh water."
Trim 1-2 cm from stems
During warm spells, flowers need to absorb water quickly. The ends of stems can become dry or sealed during transport. Trimming 1-2 cm from each stem at an angle creates a fresh surface for water uptake and improves hydration. Using a thoroughly cleaned vase is also important, as bacterial growth increases in warmer temperatures.
Keep flowers topped up with fresh, cool water
Heat causes water to evaporate faster. Varley advises: "During a heatwave make sure to check your vase every day and keep it topped up with fresh, cool water. If the water starts to look cloudy, replace it completely and give the vase a quick rinse to reduce bacteria." Lightly misting flower petals with a spray bottle can also help maintain moisture levels.
Don't skip the flower food
Flower food provides vital nutrients and prevents bacterial growth. Use the sachet provided with bouquets and include fresh flower food when replacing water. Varley adds: "If you run out of the sachet and can't get any more, you can make your own flower food by combining a litre of water with one tablespoon of vinegar and one teaspoon of sugar as a quick backup."
Avoid direct sunlight and airflow
Place cut flowers in a cool, shaded spot away from sunny windows and heat-producing appliances. Avoid placing them directly in the airflow of fans or air conditioning, as this can dry out petals. Moving the bouquet to the coolest room overnight can also help extend its lifespan. Choosing a slightly larger vase with a wider neck permits better air circulation.
