Hi
I'm about to plant out a hedge of Glauca conifers but am getting mixed answers regarding the spacing.
We want them to form a hedge eventually and they are being planted in a narrow space at the side of the house that is approximately half a metre in width by 14m in length. The tag says they grow to a width of 80cm but we have Glaucas planted elsewhere and after nearly 5 years they seem to be 30cms. Assuming they'll thicken up over the years (or will they?) does that mean we should plant at 80cm apart? Or 50cm to guarantee a screening hedge?
Thanks in advance!
