Weed Identification & Control in Fort Collins, Colorado

Why lawn weed control matters

  • A weed is simply an unwanted plant that can grow in your lawn, your garden, or any place with dirt on your property.
  • The more weeds you have, the less room there is for your lawn to grow. These weeds spread throughout the landscape & can do extensive damage if not treated the right way.

The two main types of lawn weeds

Generally speaking, weeds that appear on lawns in the United States fall into two main categories: 1.Broadleaf weeds & 2.Grassy weeds.

Broadleaf weeds generally have wider leaves & include weeds like dandelion, purslane, & clover. Some broadleaf weeds may flower, & look like pretty plants, the way dandelions, wild violet, & thistle do, but don’t let them fool you. These weeds can become invasive quickly if not regularly treated with herbicides or hand pulled at the root.

One of the problems with grassy weeds is that they grow under the very same conditions as regular grass, so treating your lawn could inadvertently end up growing the weeds as well. A pre-emergent is recommended in early Spring.

Annual vs. perennial weeds

One size does not fit all when it comes to weed prevention & removal. That is because weeds can either be:

  • Annual – growing season is one year or less
  • Perennial – weeds continue over multiple seasons.

Perennial weeds establish roots in your lawn, & can last for multiple seasons. Getting rid of them can be tough, because they need to be treated or removed entirely, including the full roots, or they will just keep on growing.

Different weeds grow in different seasons

Just like lawns, weeds can fall into cool-season & warm-season types, growing best during certain times of year.

As there are literally hundreds of different kinds of weeds, effective treatments will vary. There is no one set time that works for all weeds & multiple weed control treatments throughout the growing season are recommended.
