We've been using plastic kiddie pools for the geese and dogs for over a year now. We've gone through quite a few, as the dogs tend to punch holes into the pools with their nails. Never was able to throw the pools away, and tried a variety of methods to patch & re-use, to no avail. Now we've found an honorable way to re-use those pools... as raised garden beds!
First, I cut large holes out of the bottom to allow root & water penetration. Didn't cut away too much, however, as I wanted the pools to retain some strength and structure:
Then we filled the pools with soil. Renting the backhoe/loader saved us hours of labor:
The loader bucket was wider than the pools, so we still had to do some soil shoveling, but not too much:
End result: all of the pools re-used.
Final pic: Spouse having a good time on the rental unit.
We also filled in a longstanding hole, and Spouse found actual soil on the property. We were going to put the goose pool in that initial spot, but have decided to save it for orchard trees. New pool spot: in front of some young oaks. More updates later!
