Pre-emergent weed control in Yakima
Weeds take the nutrients and water your grass needs. Colonial's Yakima office applies high-grade pre-emergent herbicide so the weeds never get started, and so landscaping later is not affected.

How pre-emergent helps
Prevents growth
treatments target weed seeds in the soil before they grow into plants.
Timing
most effective in early spring or fall, before germination.
Common weeds
works on crabgrass, dandelions and more.
Why not a sterilant?
People ask for a sterilant, but there are no legal sterilant materials for homes. What most people think of as sterilant is restricted to airports, railyards and heavy industrial sites. Washington State law prohibits any material that lasts longer than a year on residential property, whether a commercial applicator or the homeowner puts it down.
We use high-grade pre-emergent herbicides instead. They protect against broadleaf and grassy weeds all season and, if you landscape the treated areas later, there are no long-term effects.
Why Yakima homeowners choose Colonial
As a Yakima-based company we know the weeds that turn up in Yakima lawns, and our crews use reliable products and methods. We also offer the rest of the lawn care you need, from weed control to fertilizing, so the lawn is handled by one team.
Preventing weeds costs less than treating them after they spread, and it leaves you more time to enjoy the yard instead of pulling weeds.
