Setting a Spreader for Weed & Feed

Not all lawn fertilizers are alike. Neither are the spreaders used to apply granular chemicals to your lawn. Weed and feed describes lawn fertilizers that include a herbicide along with essential nutrients. The weedkillers kill broad leaf weeds and crabgrass. Setting the spreader correctly is important because applying weed and feed incorrectly can damage your lawn or surrounding plants.

Consult the Fertilizer Packaging

Because each brand and product has different granule sizes and formulations, check the fertilizer packaging for recommended settings. Most fertilizer manufacturers have websites with tools that allow you to set the spreader correctly. The weed and feed package usually has the setting numbers for various spreaders written on it.

Spreader Models

Each spreader model distributes fertilizer differently. So, it’s also important to consult manufacturer guidelines when applying weed and feed products. Model types often broadcast granules differently than those of other manufacturers. Factors to consider include rate of application and whether the spreader is a rotary or drop type. Manufacturer websites often have a tool that allows you to determine proper settings. Make sure the control levers are in the “off” position before filling and setting spreader controls.

Generic Settings

If you can’t find setting information for your model, calibrate the model by measuring fertilizer to cover 100 square feet according to package directions. Set the spreader on low, and spread the material. Ideally, the product will run out when you get to the end of your test area. Adjust settings upward or downward according to your results.

Spreader Settings: What You Should Know

Before you can apply any BioAdvanced granular lawn fertilizer or weed, insect or disease control product, you must set your specific model of spreader to the appropriate settings. The wrong settings can result in over- or under-application, unsatisfactory results and possible damage to the lawn or surrounding environment.

Before you begin, check the product package.

Recommended spreader settings are usually listed on the product package. Different types and models of spreaders apply granular lawn fertilizers and pest control products at different rates. This is a function of spreader design as well as the granule size and consistency of the product you are applying.

Your spreader is NOT listed on the package?

The truth is there are just too many spreader models and manufacturers to test and list them all. If the setting for your spreader is not on our package, the first thing you could do is visit the spreader manufacturer’s website and see what kind of help they offer. They probably won’t have specific settings for BioAdvanced products, but they should have information on how to calibrate your spreader so it applies the right amount of product over a specific area. You can always contact BioAdvanced at 1-877-229-3724 or use our live chat feature at BayerAdvanced.com for assistance. Your local Cooperative Extension System office may also have information on how to calibrate your spreader.

REMEMBER: The goal is to calibrate your spreader for a specific BioAdvanced product. Other BioAdvanced products, or products from other manufacturers, will require a different setting.

In a nutshell, here’s how to calibrate a spreader.

For most BioAdvanced products, the goal is to apply a specific number of pounds of product per 1,000 square feet. Using a tape measure, accurately measure off a specific area on a hard, easy-to-sweep surface, such as a driveway. It doesn’t have to be the entire 1,000 square feet. Half or quarter of that area may work as long as you remember to also adjust the desired amount of product to be applied as well.

Keep in mind that broadcast spreaders apply granules over a wider area and may need the larger space for proper calibration. Broadcast spreader passes must also overlap according to manufacturers instructions to achieve even coverage.
