Cherries
We have multiple fruit trees around our gardens. One of those trees is a pie cherry tree. These charries are pretty sour but supposedly really great in pies once you add a bunch of sugar. Instead of harvesting the cherries one by one by hand we sought out alternative measures.
Alyssa is very adventurous and loves to climb trees. So, up she went and we put down a tarp under the tree. Alyssa shook the tree and down came the cherries. It was a wonderful technique. We then had to move the tarp in a way so that the cherries would not fall though a hole in the tarp. We figured it out.
