The Local Difference
Built for Idaho Lawns, Not a National Playbook
Treasure Valley lawns deal with alkaline soil, hot dry summers, fast spring weed flushes, and billbug pressure that national franchise schedules simply don't account for. Diamond Lawns has been family-owned and based right here in Meridian since 2006 — our programs are timed to Idaho's actual growing season.
That's why we feed cool-season turf hardest in fall, put pre-emergent down before Boise's crabgrass window opens, and treat perimeter pests when they're active in our climate — not when a corporate calendar says so.
Complimentary assessments. Meticulous, detail-driven service. Priority care for annual program members.

Common Questions
Lawn & Pest Questions, Answered
How much does lawn fertilization cost in Meridian, Idaho?
Pricing depends on your lawn's size and the program you choose. Every Diamond Lawns quote starts with a free, no-obligation inspection and estimate, and customers who enroll in our annual treatment program save on every application. Call (208) 484-5568 for an exact quote on your property.
How many fertilizer applications does an Idaho lawn need per year?
Most Treasure Valley lawns perform best with 5–6 applications per year: early spring with pre-emergent, late spring weed control, two summer feedings, an early-fall feeding, and a late-fall winterizer. We time each round to Idaho's climate and your grass type.
Is your pest control safe for kids and pets?
Yes. We use family- and pet-friendly products and application methods, and we'll tell you the short re-entry window after each treatment — typically just until the application has dried.
What areas does Diamond Lawns serve?
We serve the entire Treasure Valley: Meridian, Boise, Nampa, Eagle, Caldwell, Kuna, Star, and Middleton. See our service areas page for details.
Do you offer free estimates?
Yes — inspections and estimates are always free. Request yours online or call (208) 484-5568.
