As growth slows, the Scotts Miracle-Gro Company is looking to the expanding medical marijuana industry as a new source of revenue.

Scotts' Chief Executive Jim Hagedorn told the Wall Street Journal that he is exploring medical marijuana and other niche markets to help boost sales. The company currently relies on major retailers like Home Depot, Lowe's and Wal-Mart for nearly two-thirds of its revenue, but they as the growth of these key retailers has slowed, so has Scotts' sales.
