How To Deadhead Flowers
What is Deadheading?
Deadheading is the process of removing fading or dead flowers from plants. This in turn benefits flowering plants as it encourages them to produce new flowers. It also directs energy into stronger growth and prevents petals from dropping everywhere keeping them looking attractive, whether in beds and borders, containers or hanging baskets.
You can deadhead whenever needed between spring and autumn, removing flowers as soon as they start to look less beautiful.
How often to deadhead flowers?
If you can get into a weekly routine of deadheading the waves of blooms can be extended by weeks or months.
Where to cut?
Prune back to a new flower or bud using a Pruner. If no new flower is visible, prune the stem back to the first visible knuckle.
This ingenious Bypass Cutter is ideal for thorny stemmed or skin irritant plants, from roses and brambles to rue/ruta. When the pruner is squeezed close the grip locks onto the stem, holding it firmly in place until release, without having to ever touch the stem.
Some hardy geraniums, delphiniums and lupins produce a second flush of flowers if cut back close to ground level.
This is known as the Chelsea Chop, as it is carried out at the end of May, at the time of the RHS Chelsea Flower Show.
What happens if you don't deadhead your plants?

How to deadhead Daffodils
Take care that only the flower head of the Daffodil is snapped off, this can be done by merely squeezing out between finger and thumb or a quick cut with secateurs. Ensure the foliage is kept intact as similar to all other bulbs, they need to allow their foliage to die back normally so that its energy can be reinvested into the bulb to help generate even better blooms the following year.
