The Missouri Department of Conservation is encouraging Missourians to celebrate Arbor Days in April by planting native trees and practicing proper tree care. Missouri Arbor Day is on April 3rd, while National Arbor Day is on April 24th. The department provides resources for tree planting and care, including low-cost native tree and shrub seedlings available at local nurseries.
