The Anderson's 21-0-10 Fertilizer w/ 0.25% Dimension, manufactured by the Andersons, is a quality 2-in-1 product for cool-seasoned turf and warm-seasoned turf that prevents broadleaf and grassy weeds, kills emerged crabgrass and fertilizes your lawn and ornamental turf. 

This product contains 0.25% dithiopyr, which is known for its pre-emergent and early post-emergent weed control capabilities. It effectively prevents crabgrass, foxtail, goosegrass, and over 45 other grassy and broadleaf weeds. Additionally, the 21-0-10 fertilizer blend supplies essential nutrients to promote strong root development and lush green growth.

The Anderson's 21-0-10 Fertilizer w/ 0.25% Dimension is a powerful dual-action herbicide that controls weeds and feeds and strengthens turf with its slow-release design. This helps prevent nutrient leaching, reduces mowing frequency, and minimizes growth spikes that can stress the turf.

Tools Needed

It can be applied with a push spreader or broadcast spreader.

How to Use

  • Step 1: Determine how much Anderson's 21-0-10 Fertilizer w/ 0.25% Dimension to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). Depending on what region you live in will determine the application rate. If you live in the north use 2.3 pounds of Anderson's 21-0-10 Fertilizer w/ 0.25% Dimension per 1,000 sq. ft. If you live in the south apply 4.6 pounds of product per 1,000 sq. ft. Do not apply more than 4.6 lbs. per application, and no more than 13.8 lbs. per year. Refer to the product label for specific application rates and restrictions. 
  • Step 2: Calibrate the spreader to the proper calibration then load the correct amount of granules into it.
  • Step 3: Spread the granules evenly across the treated area. One day after application, irrigate the treated area with a light amount of water. For split-applications, wait until 6-8 weeks have passed after the first application before retreating. 

Where to Use

The Anderson's 21-0-10 Fertilizer w/ 0.25% Dimension can be used in established lawns and ornamental turfs, including golf course fairways, roughs, and tee boxes.

Do not apply to flowers, vegetables, shrubs, or trees.

When to Use

Apply before weeds are present during the spring, summer, and fall. 

Postemergence applications are only effective on crabgrass if applied before crabgrass has displayed its fifth leaf or first tiller.

Safety Information
