Does anyone have any idea why our grass is doing this? It’s like a strip of greener, thicker, healthier grass in an arc shape? It grows faster than the rest of the grass. We never drive on it.

    Who cares what’s up with your grass… have you seen he view from your front yard?

    Maybe it was seeded with a different type of grass at some point?

    Perhaps it is/was a swale and had something changed about it

    Septic field? I don’t think I’ve seen any that long and narrow but grass grows like that over septic fields

    Thicker layer of material that retains water there I would assume

    It could be a single leg of your leech that’s clogged, but it could also be a natural swale that’s just a little better at holding water and nutrients than the rest.

    Is it flatter there? Could be holding water longer.

    Did you have something installed underground in the last year or two? Usually (when you install something like a sprinkler system), you’ll see grass do really well where the trench was dug because the soil isn’t as compacted there. So it’s able to grow deeper roots allowing it to access more water.

    It takes some time for it to even out. It’s been two years since I installed my sprinkler system, and the all the grass along the trenches greens up much faster in the spring and stays greener longer.

    Right now we are in a drought, so I only water twice a week which makes the lines much more prevalent. Less noticeable when I can consistently water.

    Almost guarantee there is tile under there.

    Is that where your dookie water goes?

  10. We have a full circle like that where there is mushroom network underneath! They pop up in the fall exactly in this place.

    Water makes it look like the that maybe a stream under it?

    Leach field is the obvious answer. But since it is all the same height on the hill, I wonder if another possibility is that subsurface water coming from the top of the hill could be making its way to the surface right there.

    I would wager that water is migrating along a sediment layer, emerging there like a natural spring. I would further wager that this is the result of a major resloping landscaping effort when the house was built.

    Our neighbors have a similar situation in their back yard, though in their case it is a bigger slope and the water actually bubbles out after heavy rains.

    The reverse happens in historical sites, where buried walls of buildings go brown quicker in dry weather. A few old ruins have been discovered that way in the UK during heatwaves.

    My guess this could have been a ditch, or other ground disturbance that was filled in. The topsoil there holds onto moisture better, so better growth.

    Is there septic or irrigation lines that run there? That’s most likely.

    Any chance you have a reoccurring rainbow in the sky blocking the sun on really sunny days?

    That was where some compost or something similar was dropped off.

    The big spot is where they left a few tons.

    The lines are likely from where the truck damaged/compressed the soil and the homeowner used what they had available, the compost to fill the divers.

    That’s my Sherlock’s best guess.
