Yellow flags for visible yard notes

Swanson Tool FY15100 Yellow Marking Flags give lawn and garden checks a small visual marker. The pack includes 100 flags with 15 inch wire staffs.

Use them to mark sprinkler heads, patch edges, bed corners, seeded spots, and temporary route notes during watering work.

Useful around sprinkler checks

Sprinkler output checks often need clear locations. A yellow flag can mark where a gauge cup was placed, where a dry edge appeared, or where the sprinkler head should stay visible before mowing.

That visual cue helps the next garden walk start in the right place.

Pair with notes and gauges

A flag can hold the place while a notebook holds the detail. Write the date, area name, run time, and reading, then leave the marker where the next check begins.

This works well for patch repair, lawn strips, vegetable-bed edges, and irrigation head checks.

Good fit

This pack fits gardeners who need a supply of small yellow markers for short-term lawn and garden tasks.

What to know

Remove flags before mowing or edging. Store unused flags in a dry bin so the wire staffs stay straight and easy to place.
