How to Take a Turfgrass Sample
If your grass has ever developed discolored patches, you might've wondered if you could somehow take it to the turf doctor. The answer is yes!
Start with a clean shovel and target the border between the green, healthy grass and the discolored-looking grass. Dig up a four-inch by four-inch square of grass, including the roots.
To ship the sample, shake off excess soil and wrap the grass in aluminum foil. Place it in a sturdy box and select overnight or two-day shipping. Don't forget to include a completed plant diagnostic form and payment.
