Submitting Samples
- Collect and submit samples early in the week, especially if sending by mail.
- Send an adequate representation of the problem. Select samples from the transition zone between healthy and affected turf. Sample when symptoms are evident.
- A 6" plug is a good size to submit. Include the roots. Plugs taken with a cup cutter are ideal. Samples collected with a soil probe are too small.
- Submit fresh samples. Package and mail immediately. If a sample must wait, put it in a cooler or refrigerator. DO NOT SEND DEAD GRASS!
- Package plugs with different problems separately.
