Tree Planting

Today, we planted a variety of trees such as a Rowen, Blackthorn, Hawthorn, Crab apple and Alder. Before we planted the trees we did a bit of research on the different trees. We learned lots of folklore for each tree and chose the one we most liked. We then planted the tree and made the surrounding area visible to others so that our tree does not get trampled on.

Tip: Count the rings.
