Landscaping metal stakes

[magic]

Just an observation, you know those u shape metal stakes that you use in the black cloth covering that is used to block weeds from growing around shrubs and flowers? Well I have those at my home and I notice that in the spring, I always have to push them back down. They seem to rise up about an inch from fall to spring. With this being true, I wonder if this holds true for coins and other stuff in the ground. Maybe water gets under these and freezes and drives them up.

Does anyone have a thought on this?

Morning Magic....

My thoughts on this are that the ground shifts when frozen depending on the moisture in it. The higher the water content, the more heaving that occurs. When the ground heaves from frost, it also expands from water turning to ice...thus...kind of "puffs up" . When the ground then thaws in the spring, the dirt loosened by this process settles back down. This cycle, I feel, is what takes our targets deeper every year they remain in the ground. A lot of variables effect this process...such as ; makeup of ground(rocks) type of soil (sandy/clay/etc) and number of freeze/thaw cycles in a season.
I have dug mercs at 3", because they were on top of a flat rock, and have dug clad at 9"+ in loamy soil.
Just more to think about.

Your question was could this move coins up, I would think yes.
