Why start these in July rather than September?
The good window is short and everything upstream of it takes time. The best seeding period for cool-season grass in eastern Massachusetts runs from roughly mid-August into September — soil still warm enough for fast germination, nights cooling, crabgrass done competing. Grading and top-dressing have to happen before seed, so ordering soil the week you want to seed means you have already missed it. Plan the date against the UMass Extension turf program. Arlington adds its own wrinkle: the town climbs steadily from the low flat ground near Spy Pond and Alewife up to Arlington Heights, so a great many back yards sit on a real grade.
1. Grade and top-dress now, seed in late August
Top-dress thin turf with a half inch to an inch of good soil, rake it in, and let it settle a few weeks before seeding. Using cubic yards = (square feet × depth in inches) ÷ 324, 1,000 square feet at 1 inch is 3.1 yards. Super Loam at $65 a yard is the premium screened topsoil for it, and Compost at $50 mixed in at about a third by volume is what improves the soil rather than just covering it.
2. Fill the ruts, low spots and worn paths
Work in shallow lifts and never bury existing grass under more than about an inch at a time — deeper than that kills what you were trying to save. For anything over an inch, cut the sod out, fill, and seed on top in late August. Material is in the lawn levelling and repair collection; a 300-square-foot area at 2 inches is 1.9 yards, so order 2.
3. Re-gravel the driveway before leaf season
Gravel drives on the Heights slope take a beating from runoff, and the fix is far easier in warm dry weather than in November mud. A thin drive needs a top coat of Gray Granite ¾" at $79.50 a yard; one rutted down to soil needs base, so Dense Pack ¾" to minus at $76 in 2-inch compacted lifts. A 10-by-40-foot drive at 3 inches is 3.7 yards. Stone ships 6 yards a trip and the fee is per load, so base plus top coat is two line items and two loads. Options in driveway construction and repair.
4. Sort the downhill drainage before autumn rain
Dig an 18-inch hole, fill it with water, and time the drain; four hours or more means a subsurface problem soil will not fix. The standard answer is a stone-filled trench or dry well moving water away from the foundation, backfilled with open-graded #57 gray granite.
5. Plant trees and shrubs from late August into fall
Soil is still warm then, so roots keep growing after top growth stops and the plant goes into winter established rather than stressed. One condition: new trees and shrubs need frequent watering through their first season, and deep soaking versus daily watering has the gallon figures. The UMass Extension landscape program covers regional plant selection.
Common questions
What is the latest I can seed a lawn in Arlington?
Aim to have seed down by mid-September; later and seedlings may not root deeply enough to survive winter.
Can I top-dress and seed the same day?
You can. Letting the top-dressing settle a week or two first gives a firmer seedbed and better seed-to-soil contact.
What does delivery cost in Arlington?
Arlington is 10.8 driving miles from our Dispatch Office in Dorchester, inside the 30-mile flat zone, so $100 flat per load. Mulch runs 10 yards a trip; soil, stone and sand run 6. No minimum order.
