A gardening expert has shared a simple watering method to revive wilted hydrangeas in just a few hours. In a YouTube video, @Classyflowers, who has 338,000 subscribers, explained that hydrangeas are a 'very moisture demanding plant' and often appear dead after brief periods without water or extreme heat.
The expert noted that many gardeners discard potted hydrangeas when they look dehydrated, but they can almost always be brought back to life quickly. The key is to use an 'immersion' technique rather than watering from the top, as dry soil can fail to absorb water properly.
To rehydrate, prepare tepid water by mixing boiling water with cooler water until it is warm but comfortable to touch. Submerge the pot to saturate the soil completely. Then, spray the entire bush with water to prevent moisture loss from the foliage.
Finally, place the plant in a chilly space with temperatures between 5C and 10C to reduce evaporation. The expert demonstrated the method with a time-lapse video showing the plant recovering within hours, though some blooms that had passed the point of no return did not recover.
After rehydration, trim away all dead flowers and leaves to prevent bacterial and fungal infections. This trick comes as a heatwave forecast predicts temperatures of up to 39C in the UK.
