Pinching out the tip of branching plants is one of the most important techniques which will ensure much stockier plants that will give you many more flowers in your cut flower garden!
How it works
Removal of the top shoots (apical buds) enables the sideshoots (axially or lateral buds) to branch out.
The top shoots would normally inhibit the side shoots by producing hormones in a process called apical dominance causing the plant to just grow skywards.
Do not use this method on single stem plants such as stocks which give you just one flower per plant, this also includes single stem sunflowers and bombay celosia.
This method is also used on perennials, often referred to as the ‘Chelsea Chop’, it reduces the need for staking and you have more flowers, just a tiny bit later.
Perennials need this treatment around the end of May at the same time as the Chelsea Flower Show, hence the name!
