Almost have the flex down perfect. I have two large Oak Trees. One each in both my front and backyard zones that are on a moderate incline. Both trees are centered in the top 1/4 of their zones. The rest of the zone is cool season grass.
I’d appreciate a recommendation. The grass tends to stress out under the root zones to the tree drip lines going downhill. I believe an adjustment to the crop coefficient in these zones is needed. Not sure what the correct number (or reasonable ballpark) would be and any suggestions would help!
Location (Boston Area)
Matching Zone profiles:
Current co-effeicent is: 0.7
4" Cool Season Grass (Sun & Seed turf w/ bluegrass seasonally over seeded into the mix)
Root depth: 6.5"+ set to 5.5" to match weakest areas. (under tree root zones on hill)
