There are three different sizes of trees Hoerr Nursery offers. Ella Maxwell talks about how Hoerr Nursery can assist with your new tree, whether you do it yourself or have Hoerr plant it for you. The first important item to address is making sure utilities aren’t present where you would like to plant your tree. Avoid July & August to plant a tree because of heat & dryness. Space your tree 20 feet from your house. There are a number of organic matter products you can choose to assist your tree’s growth, especially in the early stages.
