I planted a copper beech hedge 11/2 years ago and it is still very sparse. Just recently, some long shoots have started to grow and I cut these to try to encourage low growth. How can I thicken up my hedge? This is my second attempt. My first bare root hedge failed.
When the trees grow , some low-lying shoots will eventually fill out the base, or else plant more young plants along the base to fill for a quicker result.
