While walking across campus a few weeks ago, I noticed the unusual turf coloration along sidewalks throughout campus.
Wondering what our faithful blog followers might think the cause of this turf discoloration to be? Is it anything to be (potentially) worried about? I know it's covered under many inches of snow right now - which I barely escaped by leaving for San Antonio around noon on Saturday (it was 81 F when I landed).
I'll post the cause of this mysterious discoloration in a few days. Please post your guesses below!
Hmm. Although it looks like tire tracks from the snowplow, I'm going with salt. Or at least a deicer.
ReplyDeleteGood guess Wanda. A very logical one. But it's not deicing salt injury. Hmmmmm....
ReplyDeletePossibly damage by mini sidewalk plows? The damage appears to be uniform on both sides.
ReplyDeleteBecause it is uniform, it could be a sprinkler (water) problem where the water reaches everywhere but the sides of the grass?
ReplyDeleteI'm guessing that mites wouldn't leave that uniform damage, so I have no good guess. Looking forward to reading the solution to the mystery.

It looks to me to be from snow/ice having built up there for a long time due to plowing on those sidewalks. That grass hasn't seen the sun for awhile.
ReplyDeleteIt's possible that the grass adjacent to the sidewalk got heated enough to break dormancy (or stayed active longer last fall) and then suffered frost damage when the temperatures dropped. The left side damage is wider than the right side and both exactly parallel the walkway. Probably the left side faces south and gets more sun; notice the shadows from the trees.
ReplyDeleteI'm guessing damage from ice buildup....
ReplyDeletewill be fun to see answer to this one!
Could it be edger damage? A weed eater trimming too close?
ReplyDeleteOk, I'm back. One more thought is that the grass has overgrown the sidewalk on both sides so that what looks like grass on dirt may actually be grass overgrown on concrete. I have no idea why someone would trim grass to overgrown in that manner. But i see homeowners with trim overgrowth on my walks. (Ok, along my front walk

DeleteMaybe not. Is edge more shallow? So maybe lack of drainage is causing water/ice buildup? Hmm..final answer..maybe.
DeleteIs the damage from using IceMelt?
ReplyDeleteIt's from the tires on the truck that's clearing the snow from the sidewalk!! Final answer.
ReplyDeleteGlyphosate?
ReplyDeleteJames Johnston, I bet you are right!
ReplyDeleteCan someone tell me why my posts say "Reply Delete"?
ReplyDeleteI would have guessed ice melt injury, but perhaps it was damage from a sidewalk plow.
ReplyDeleteI think it's the result of a sidewalk snow plow that pushed the salt laden ice/slush onto the grass.
