Plant a Tree in a state of your choice by providing an email address. Click on Start Here. Here is a screenshot for your reference. There is no cost to any participant and the cost of the trees is paid by Odwalla. Limit one tree per person. There is a total of 175,000 trees that will be planted in the state parks. If for some reason a state cannot or does not want to accept the donation, then it would go to a non-profit that would plant trees in that state.
