initial pruning of new yew hedge
I have just completed a 20 foot length of standard yew hedging. The plants were a good buy of 5 per pack from our garden centre and are really sturdy plants around 30 inches high.
I intend to keep it tightly clipped and narrow once established and around 5 foot tall. Do I take out the leaders now and clip the side stems back to thicken it up or wait until the plants are a lot bigger?
