New supplies are needed all the time in our active tree growing project. The wheelbarrow is our most used equipment for carrying dirt, supplies, seedlings, and anything else that has some weight to it. We use it every day to move trees and soil around; replacing it cost us $60.
Last month we had to replace a $50 watering hose after a stray dog chewed holes in it. These tools are necessary but not in the budget, but thanks to surprise one-time donations we were able to get them replaced.
