Is 1 meter (3.2') spacing between blue spruces right?
We live in zone 5B, and our north-west side faces a local highway, so we got strong winter wind and daytime cars. We selected blue spruce to cover the 900 property line. To start, we had a local tree farmer dug out 260 blue spruces from his densely planted farm area. He instructed us to plant them in two rows, leaving 2 meters (6.5')between each rows, and 1 meter (3.2')between each tree. That way he told us that the branches will really "embrace" each other.
Now after finishing those 260 trees, we found that the trees are too close. So we stopped ordering new tress and started to search the internet and asking people. My opposite neighbor who planted a row of white spruces 15 years ago, with a distance of 2 meters, now aren't get their tress in good and full-growth form, especially with the lower branches.
Should we space it otherwise? Is the instructions from my nursery right? The snow is not coming yet, so we might have time to redo it.
Please help. Thanks.
