Can I use any brand of fertilizer in this spreader or does it only have to be Scott’s?

Scotts Turf Builder Mini Broadcast Spreader can be used with any fertilizer. To find the correct setting if not listed on the bag for this spreader you will need to do a test area of 50 X 20. Place enough material in the hopper to cover 1,000 sq. ft. (Usually indicated on the bag of product, if not indicated, take pounds in bag and divide by the number of thousand square feet bag covers. Example: 23lb bag covers 5,000 sq ft, divide 23 by 5 to get 4.6lbs per 1,000 sq ft). * Place the spreader setting on a low setting (Usually one-fourth of the spreader setting range or less). * Spread the material over a 50 x 20 ft. area (This is 1,000 sq. ft.). * If material is left over, they need to increase the setting. * If they come up short, they need to decrease the setting. * While this is not a scientific method for getting the spreader setting, it will get them in the ballpark for their product or spreader.
