Fertilization and weed control in Fort Collins

Five rounds a year, from the crabgrass pre-emergent in April to the winterizer in November, each one priced from the grass we measure.

We measure the mowable grass, not the lot size. No account, no email.

Granular fertilizer

A lawn on the Front Range grows in clay soil, through a dry summer and a sudden fall. Each round below is timed to one of those, rather than to a date on the calendar.

The five rounds

  1. Early spring. Slow-release fertilizer and a crabgrass pre-emergent, as the soil warms in April.
  2. Late spring. Fertilizer and broadleaf weed control, for the dandelions and clover that came up anyway.
  3. Summer. A light slow-release feeding and spot weed control, gentle enough for a lawn under heat and watering limits.
  4. Early fall. Fertilizer and broadleaf weed control, when weeds are taking food down to their roots and die best.
  5. Late fall. A winterizer, which the roots store over winter for the spring green-up.

Every round is recorded: what went down, how much, where, the weather at the time, and who put it down. You can see the record for each visit in the app.

What it costs

A round costs 1.3 times the weekly mow of the same lawn, so a lawn that pays the mowing minimum pays a round. A bigger lawn is priced on the grass we measure. All five rounds and a season of weekly mowing come together on the Lawn Season Plan.

Questions

How much does lawn fertilization cost in Fort Collins?

The table above gives four lot sizes, and the address gives you the figure for yours.

Is it safe for children and pets?

Keep them off the lawn until it has been watered in or has dried; the crew tells you which on the day.

What if weeds come back between rounds?

Tell us, and we come back to treat them before the next round at no charge.

Do I need to be home?

No. We need a way into the back yard, and we text when the round is done.
