How to Troubleshoot an Ortho Lawn & Garden Sprayer

The Scotts Miracle-Gro company began as a farming and agricultural seed company founded by O.M. Scott in 1868. By the 1900's the company began producing grass seed products for homeowners. Ortho, a division of the Scotts Miracle-Gro company, manufactures a line of sprayers to apply its herbicides and weed killers or to deliver fertilizer and nutrients to lawns and gardens. While the Ortho Lawn and Garden sprayer is no longer being made, the most common Ortho sprayer used today is the Ortho Dial 'N Spray Multi-Use Hose-End Sprayer. If your sprayer doesn't spray properly, disassembling and cleaning it may get it working again.

Consider changing to a larger sprayer for big lawn and garden jobs.
  1. Detach the Ortho sprayer from the hose, if so attached.
  2. Separate the feed bottle from the lid and sprayer attachment.
  3. Unscrew the end of the sprayer and run it under hot water. If the unit sat all winter without a cleaning prior to being put away, chemicals crystallize within the sprayer and block fluid flow.
  4. Soak the sprayer attachment lid and all parts in hot water to dissolve any leftover chemical crystallization.
  5. Reassemble the sprayer, add hot water to the feed bottle, attach it to the hose and empty the feed bottle completely by turning on the hose water and using the trigger.
  6. Add the appropriate chemicals to the feed bottle and use as you normally would.


  • Always clean the sprayer and wash it thoroughly after each use to prevent crystallization and buildup in the nozzle attachments. If the trigger is broken, replace the unit because there is no repair for a broken trigger. Consider purchasing a backpack sprayer or separate unit if you do a lot of spraying. The Ortho Lawn and Garden Sprayer is for small jobs only.


  • Always wash your hands when working around fertilizers or other harsh herbicides and chemicals. If you have sensitive skin, wear garden gloves when working with these items.
