We were lucky to have a friend with a greenhouse, who had lots of extra plants (trees!) he was trying to find homes for. We were the recipients of about 3 dozen baby tree lilacs, and around 10 baby Osage Orange trees (plus a number of magnolias and redbuds). We designated a nursery area, on the west side of our property. Here, we could easily keep an eye on things, and the hose reached over there as well.
We found a source for wood chips. You can never have enough wood chips. We covered our tractor with a tarp, and we covered the nursery area with straw, for the winter.
