To apply the SITEONE LANDSCAPE SUPPLY LLC 052388 Crabgrass Preventer Turf Fertilizer using a Scotts 3000 spreader, you’ll need to adjust the spreader settings appropriately. While the specific setting for your exact product isn’t directly available, I can provide you with some general guidelines based on similar Scotts products. Broadcast/Rotary Spreader (Scotts 3000): Set the spreader dial to 3. Drop Spreader (Scotts 3000): Use a setting of 6 ¼. Wizz Spreader (Scotts 3000): Set the dial to 3 ¾. Remember that for optimal results, your lawn should receive ¼ to ½ inch of water from rainfall or watering within 2-3 days after applying the fertilizer1. Happy gardening!
