Gardeners urged to prune hydrangeas at 'correct time' to avoid major problem According to the green-fingered gurus at the Royal Horticultural Society (RHS), the most commonly grown hydrangeas in the UK are lacecaps and mopheads.
For any hydrangeas which are established, it is advised gardeners cut one or two of the oldest stems at the base to encourage the production of new, replacement growth that will produce more flowers.
The pros added: "Remove the dead flowerheads in early spring, cutting back the stem to the first strong, healthy pair of buds from the faded bloom.".
It's crucial to prune hydrangeas at the right time of year or Brits could risk chopping off the next year's flower buds.
Although the blooms on mophead hydrangeas can, in some mild areas, be removed as soon as the colour has faded, experts recommend leaving them on to plant over the winter months.
