Plant your own tree

Whether you are a homeowner, a business, or an institution, planting trees on your property counts towards the Green Leaf Challenge! Once you have planted your tree, make sure to map it online at

What are the next steps after planting?

Once that tree is in the ground, we want to make sure that it grows strong and healthy. Your tree needs to be adequately watered throughout the growing season (spring to fall). Applying mulch around the base of the tree can also help add moisture and nutrients to the tree.

How do you plant the tree?

Make sure to clear out anything on the ground surface that may be in the way of planting your tree including grass or cover plants. Another common mistake that people make when planting trees is the size of the hole. Focus on making a hole that is twice as wide as the root ball of the tree and just deep enough to fit the roots. The roots need lots of room to grow once the tree is established.
