Planting under a large Norway Spruce
I have a large Norway Spruce that I would like to plant some understory plants under. This tree had been around for 50+/- years, stands about 50-60 feet tall*, and about 25 feet across. I would like to plant a number of camellias under it - about 10 feet out from the trunk, and spacing about every 4 - 5 feet all the way around the tree.
So, my question: will this seriously injure my spruce? If I dig about 15 holes around this tree, each about 12 -18 inches deep, I will invariabley run into some of the tree roots. Assuming the worst, that I cut through a number of these roots, how will I impact my tree?
Thanks for your advice,
*Actually the tree USED to be about that height until that wild derecho storm that blew through Virginia last summer, and knocked about 20 feet off the top.
