Need a free tree? Head to Lowe's

If you're looking for a tree to plant this Earth Day but can't bring yourself to pay for one, try Lowe's. The Mooresville-based home improvement retailer will be handing out a million saplings this Saturday at its stores around the country.

The trees are being given away in partnership with conservation group American Forests. Lowe's says the types of tree at each of the company's 1,725 stores have been selected to thrive in the local environment. They'll be free while supplies last.

And in a nod to the growing role played by social media and mobile technology in retail, you'll have a couple of different ways to learn about your saplings once you bring them home. Each tree bag will have a bar code, Lowe's says, that you can scan with your smartphone. That code will take you to a page of tree facts and a video for how to take care of your sapling. And Lowe's is inviting customers to share their tree stories on LowesCreativeIdeas.com.
