My back yard stuff

So my grandpa was pulling weeds and I wanted to go help him. When I was pulling weeds I found these things. We had just made another garden and it worked so well but it didn't have enough space so we decided to make to more little gardens. We are going to put kale and a lot of other very healthy veggies. There was tons of huge roots because we took the blackberry bushes out of the earth but some of the roots stayed.



I think these Things which look like they go to plates or cups are over two hundred years old but I have no idea how old they are. I found that one with the blue stuff and white on it in the other garden.
