So you have weeds in your lawn in Colorado. What do you do to keep them at bay?

The ideal time to deal with lawn weeds is in the late summer and early fall. The best way to have a weed free lawn is to have a healthy lawn.

Fertilization:
Healthy lawns are fertilized, particularly in the fall so that during the winter the grass has time to recover after our stressful hot, dry summers in Denver. Fertilization programs help the turf

Hand Dig or Mow weeds to prevent from going to seed:
In the spring and throughout the summer, it’s easy to hand dig those occasional weeds such as dandelions with a weeder (on right) as soon as you see them so they don’t go to seed and spread in your yard.  Mowing is also effective to limit seeds from spreading! For flower beds and gardens, a 3-4″ layer of mulch is very effective at controlling weeds.

Irrigation:
Healthy lawns also receive regular irrigation in the summer months into the fall. Make sure that your sprinkler/irrigation system is well-maintained and is sufficiently wetting the yard. Water longer, and less frequently, to help the lawn build deep roots.

Herbicides:
Herbicide treatments may be necessary in extremely weedy situations. First you want to  identify the weeds.

“A couple of hard frosts will kill some weed species, which means herbicide treatments are not only unnecessary, they’re wasteful. These weeds include broadleaf summer annuals such as purslane, knotweed and pigweed; and grassy summer annuals like crabgrass, goose grass, barnyard grass and foxtail.” ~ www.ext.colostate.edu
