The holiday is meant to encourage the planting and nurturing of trees. Many states around the country also recognize the holiday.
The tree-honoring occasion originated in Nebraska City in 1872, founded by Nebraska City native and U.S. Agriculture Secretary J. Sterling Morton. An estimated 1 million trees were planted that day.
Nebraska City residents will hold their 141st Arbor Day celebration Friday and will extend the festivities into Saturday and Sunday, with tree giveaways, a parade, races, home and garden and craft shows, a chili cook-off and commemorative tree plantings.
