Rotor placement around trees
Hey everyone,
I'm beginning to design a sprinkler to put in by next summer, and I'm running into some design problems. I'm on a corner lot with 7 HUGE pecan trees in the front yard, a few of which have split trunks that are easily 3-4 ft wide. I originally wanted to just place rotors around the perimeter of the yard since its only around 25' wide and that would have given good head to head coverage across the yard, but I'm afraid that the tree trunks will cause uneven coverage and dry spots when they block the stream. There's one spot in particular where two trees are close to the two corners where rotors should be, and they'd block more than 50% of the area.
How do you design around this? Would it be better to just plan for 3 rows of sprays instead of rotors? I hope to have some down time this weekend and get dirty in visio or sketchup to see exactly how the coverage would be affected. I'll put what I design so you all can see what I mean.
Thanks!
EDIT: I started to draw my lawn in Sketchup using a rough survey from when we bought the house, and kept thinking that something wasn't right with the dimensions... Sure enough, the house was the right size, and the yard size was WAY off. The grass is more like 35-45 feet wide at parts, which is going to make this even more difficult. I didn't really want to put any sprinklers under the canopy of the trees as I don't want to disturb their roots, but it seems as though that's going to be unavoidable, as I only have 55PSI static pressure from the city.
