Lawn and Tree Care

Our lawn care program is based on a five-treatment program of granular products. We prefer granular products because we believe they are easier on the lawn and won’t burn like liquid products can. We also watch for weed problems as the season goes on and can apply post-emergent herbicides as necessary.

We exclusively use D&K Turf Products for fertilizers, chemicals, seed. This Iowa-based company has roots in our area, and they are another resource for our technicians and customers.

Our people

All our technicians are certified through the Iowa Dept. of Agriculture, and they receive ongoing, continuing education through Iowa State University extension.


Round 1 [Early Spring]

During Round 1, Linn Coop will apply fertilizer with a crabgrass preventer. This will control crabgrass and annual grasses. This round will also give your yard a kick start for the growing season. When weeds become actively growing in this application, spot treatment will be utilized. 

Round 2 [Late Spring]

In Round 2, fertilizer is applied with a pre-emergent to help with season long control of crabgrass. This will feed your lawn for the next 6-8 weeks and helps with color and root growth. A blanket application of weed control will also be applied, which helps control broadleaf weeds throughout your yard. It will take up to 2 weeks to see results from the weed control. The hard to kill weeds, like creeping charley and violets, will need to be sprayed multiple times. 

Round 3 [Summer/Grub]

Round 3 make up 2 applications that are done during the same visit. The fertilizer is a slow release with merit (Grub Control). This application is designed to help your turf survive the stress of summer, prevent grubs and will not burn your lawn. At this time, we will also spot treat weeds as needed. 

Round 4 [Late Summer]

Round 4 is the application of a fertilizer with 50% slow-release nitrogen, as well as, a blanket application of weed control. This is the most important application of the season for controlling broadleaf weeds. This treatment will prevent broadleaf weeds (dandelions) from blooming next spring!

Round 5 [Winterize]

The final round, Round 5, is the application of a fertilizer with 50% slow-release nitrogen. This is very important as it provides your lawn with the nutrients is needs to survive the winter and start off strong come spring. 

Aeration [Spring & Fall]

Core aeration pulls plugs 2-3 inches in length. For a healthy lawn, shoot for 1/2 to 1 inch of thatch. 

This will do the following:

  • Improve fertilizer intake
  • Improve nutrition intake
  • Encourage deep root development
  • Reduce water runoff
  • Improve soil
  • Reduce thatch
  • Reduce Soil compaction
  • Increase protection against drought, insects, disease & weeds
  • Provide thicker, healthier, greener lawn

 Lawn Maintenance

  • Mowing height during spring & fall = 2 1/2 to 3 inches. Summer months mower should be set no lower than 3 1/2 inches, which also helps with weed pressure. Never mow more than 1/3 of the grass blade off at one time. This means mowing multiple times a week in the fast-growing months.
  • Don't forget to do preventative maintenance on your mower once a month. This includes checking oil and sharping your blades. Dull blades tear the grass rather than making a clean cut.  
  • In the summer months try not to mow at the hottest time of the day.
  • Ideal not to mow when there is a dry period.  
  • Watering should be done in the morning between 4am and 9am.
