Hello again everyone. First off, thanks to all who chimed in with insight into our problem with our tall cedars and the lack of grass taking & doing well around their bases.......your replies were immense help and we appreciate your time & knowledge.......
that said, we are going to be installing a sprinkler system thru-out our entire 1/4 acre lot this coming fall. We have lots of lawn and big flower beds to irrigate, but the problem I "know" we will run into once we start our project is TREE ROOTS.......and LOTS of them. There are 5 old growth very tall cedars, 2 old growth very large firs, 1 old growth very large cherry and 1 old growth medium apple trees scattered on our lot (the bulk being in our back yard and 4 of the ceders are tightly spaced with approx 20 ft max between some and 6 ft max between others) Once we chart the course for our sprinkler system lay-out, I know, after pouring a big driveway and digging deep fence post for a custom bamboo fence, we are going to run into massive amounts of tree root, with a lot of it high on the surface of the soil thru-out the lot. QUESTIONS: is a full lot sprinkler system feasible on a lot with this level of tree & root growth? are we going to damage or even kill some of these trees by hacking into their root sysytems to get the trenches dug for the sprinkler system piping? what do you recommend we do? (as far as the smart / best way to get our sprinkler system in but not damage or kill the big old growth trees? once again, THANKS for you insight and vast knowledge !!
