Accuracy is everything.

For many years, The Scotts Testing Lab has been the leader in providing the accurate analysis professional growers and landscapers need regarding their irrigation water, growing media, mineral soil, plant tissue or fertilizer solution. Our laboratory staff is highly trained and qualified, with a dedication to accuracy that has earned the trust of thousands of customers across the nation and in 18 additional countries.

Like any other company bearing the name Scotts, The Scotts Testing Lab is a true innovator. This lab was the first certified by the American Association of Laboratory Accreditation, the first accredited in soil testing and the first to introduce data transfer. Plus, it's the only facility of its kind that operates under the strict quality assurance protocol that makes all Scotts products highly effective and reliable.
