How to Keep Your Plants in Bloom with Dead-Heading
By

"Off with her head" the queen shouted at Alice in the Lewis Carroll story
"Alice's Adventures in Wonderland". Now I’m not sure if Lewis had an interest in
gardening but he could well have been giving us some horticultural instruction
which will give us a longer flowering season. There is a technique known as
dead-heading, it is a simple task which takes a few minutes however adds days
and sometimes weeks to your flowering display.
How to dead-head
If you’ve never dead-headed before here’s how go about it…… Firstly keep a
watchful eye on your flowering plants, paying close attention to blooms that are
past their best. Once a flower has started to fade remove it from the plant with
a quick snip from your secateurs, alternatively knip it off with your thumb and
forefinger. When doing this try to remove just the spent flower leaving the new
buds beneath intact.
The many benefits
Your beds and borders now look neater due to the lack of fading blooms but
how else has this deadheading process helped us? Well by removing the spent
flowers we have prevented the plant from setting seed which if it did would
trigger the production of a hormone which causes flowering to shut down
completely. So by our slight tinkering with Mother Nature we can often force the
plant to put its energies into a second flush of flower production instead of
seed production. Bear in mind that your planting should have a plentiful supply
of nutrients to give a secondary flowering.
Plants that respond well to dead-heading
Dead-heading works particularly well on perennials and most annual bedding
especially Antirrhinums (Snapdragons), Violas (Pansies) and Dianthus (Sweet
Williams) although it can sometimes be impossible to carry out on very small
flowers or on very large and floriferous shrubs. Shrubs which react well to
dead-heading include Buddleia (Butterfly bush), Syringa (Lilac) and some Spireas.
Roses of course are ideal candidates for this technique to ensure more blooms
before the rose-hips form.
