How do you control weeds and crabgrass?
Weeds are opportunists — they move into thin, stressed turf. We attack them two ways: pre-emergent applications in early spring that stop crabgrass and annual weeds before they sprout, and targeted broadleaf treatments for dandelions, clover, mallow, and spurge through the season. Combined with a feeding program, the lawn thickens and starts crowding weeds out on its own.
When should an Idaho lawn be aerated?
Treasure Valley clay soils compact hard under summer irrigation and foot traffic. Core aeration pulls thousands of small soil plugs, letting water, oxygen, and fertilizer reach the root zone and giving roots room to grow. Most lawns here benefit from fall aeration every year, ideally paired with the early-fall feeding.
- Relieves compaction in heavy clay soil
- Reduces water runoff and improves irrigation efficiency
- Breaks down thatch naturally
- Best timing: September–October (spring as second choice)
Lawn & Turf Damage Repair
Brown patches that won't green up usually have a specific cause: billbug or grub damage, sprinkler coverage gaps, pet spots, or disease. We diagnose first — during a free inspection — then repair with the right fix, from insect treatment and overseeding to topdressing and sprinkler adjustments.
Sprinkler Systems
Watering problems undo good lawn care fast. We service sprinkler systems so coverage is even and watering schedules match what the turf actually needs in our climate — spring start-up, repairs, design and installation, and fall blowouts. See our sprinkler services.
Commercial Lawn Maintenance
Diamond Lawns maintains commercial properties, office parks, and HOA common areas across the valley with the same fertilization and weed control programs we run on residential lawns. Contact us for a property walk-through and bid, or see commercial lawn maintenance for what a program covers.
Landscaping, Hardscapes & Tree Removal
Beyond maintenance we design and build: sod and grading, irrigation and drainage, and water-wise xeriscaping on the landscaping side; paving, patios, fire pits, retaining walls and fencing on the patios & hardscapes side. When a tree is beyond saving we handle tree removal too.
Frequently Asked Questions
When is the best time to aerate a lawn in Idaho?
Fall (September–October) is best for our cool-season lawns, with spring as a second option. Aeration relieves compaction so water, air, and fertilizer reach the roots.
Why does my lawn have brown patches that won't green up?
The usual culprits in the Treasure Valley are billbug damage, compacted soil, or sprinkler coverage gaps. We diagnose the actual cause during a free inspection before recommending a repair plan.
