Lawn, Turf & Fertilizer

The key to a beautiful, lush, weed free lawn is consistent, proper care and maintenance.

Quality Granular Fertilizer

The proper management of lawn nutrients and the use of weed control methods will promote a thick stand of turf.

Empire Spray typically recommends 4 (optimal) or 3 granular fertilizer applications throughout the growing season.  The timelines below will achieve the best results from the product when weather conditions are favorable.

  • For optimum results we recommend 4 granular fertilizer applications 45-60 days apart.
  • A minimum of 2 treatments are crucial to maintain a lawns health quality.
  • More than 4 treatments of our fertilizer is unnecessary and environmentally irresponsible.
  • Fall application is the most important for your lawn’s health and ability to recover from winter come springtime.
  • Services are available “a la carte” – you are not locked into a “plan” you don’t want or need.

Broadleaf Weed Control

For small acreage homes, weeds can be difficult and seem never ending.

We can help by creating a weed control plan that will effectively control unwanted vegetation on many areas of your acreage.

Common Weeds in Spokane

Broadleaf weeds may include:

  • Dandelion, false dandelion, plantain,
    pigweed, lambsquarters
  • Speedwell (creeping Veronica)
  • Clovers, chickweed (common), pearlwort, yarrow,
    knotweed, English lawn daisy
  • Crabgrass
  • Annual bluegrass

More information about lawn weed control for Washington State homeowners is available here.

Broadleaf Weed Treatment

2 sprays are recommended and generally coincide with a lawn fertilizer application.  

  • Spring – April – early May (Dandelions & other early weeds)
  • Summer – late May – June (Black medic  aka Japanese clover)
  • Late Summer – July – August (Annuals, purslane, and knotweed)
  • Fall – Sept – October (the most important treatment which cleans up weeds that have seeded late or throughout the season)

Preemergence products cannot be applied safely during the heat of summer.

Crabgrass

The best defense against Crabgrass is creating a thick, healthy turf!

  • Treatment in April only, before seeds begin to germinate
  • The annual Crabgrass weed loves sunlight and hates shade
  • Appears most often along curbside, driveway, and walkways
  • Will take over in thin unhealthy growing turf areas of your lawn
