Quick Answer
A Watertown holiday stone border takes about 2.5 hours for a 12-foot run: cut a 6-inch wide, 4-inch deep trench, lay landscape fabric and edging, fill with ½ cubic yard of White Marble Rock ¾" to a 3-inch finished depth, then set evergreen swags and stake lights into the stone. The marble rock reflects house light back at the display through January and stays visible after a 4-inch snow — gray pea stone disappears under the same snowfall.
Why a Stone Border Beats a Mulch Border in December
Watertown front yards along Mt. Auburn Street and Belmont Street get heavy salt spray from city plowing. A mulch border absorbs salt and goes black by February. A White Marble Rock border deflects salt, reflects light, and reads clean from the curb through April. The stone is a winter-and-spring win, not just a holiday move.

Step 1 — Mark the Border Line (15 minutes)
Lay a garden hose along the proposed border so you can see the curve from the curb. Walk to the sidewalk, look at the line, and adjust until it reads. A 12-foot border with a gentle S-curve is the Watertown sweet spot — straight runs read industrial, hard zig-zags read busy.
Step 2 — Cut the Trench (45 minutes)
Cut a 6-inch wide, 4-inch deep trench along the hose line. The half-moon edger gives you the cleanest edge; a sharp spade also works. Throw the soil onto a tarp — you'll use about half of it for top-dressing the bed afterward, and the rest can fill low spots in the lawn.
Step 3 — Lay Fabric and Edging (30 minutes)
Roll out landscape fabric in the trench bottom. Set landscape edging along both sides of the trench, edges flush with the lawn. Stake the edging every 18 inches. The fabric stops weeds; the edging keeps the marble rock from migrating into the lawn — without it, you'll be raking white stone out of the grass every April.
Step 4 — Fill With Decorative Stone (30 minutes)
Pour White Marble Rock into the trench to a 3-inch finished depth. A ½ cubic yard covers a 12-foot border at 6 inches wide and 3 inches deep with a small reserve. Rake smooth. The trench rim should sit slightly proud of the lawn so meltwater drains out, not in.

Step 5 — Install Holiday Accents (30 minutes)
Push evergreen swags flat into the stone border every 4 feet. Stake C9 LED lights at 6-foot intervals through the swags. Add a wreath at the front-step transition. The stone holds the stakes vertical even when shovels and frost-heave hit in January.

What This Border Does in January and Beyond
Once the holiday accents come down (mid-January), the border reads as modern winter hardscape through spring. Tulip bulbs planted behind the border (not in it) push through in April; perennials bloom against the white stone backdrop in May. It's a December project that pays through October.
