Jonathan Green’s Weed & Feed Lawn Fertilizer is a premium grade herbicide and lawn fertilizer combination which controls weeds while feeding the lawn. Weed & Feed is designed to promote lush green growth in lawns and control over 250 broadleaf weeds including dandelions, chickweed, clover, wild onions, thistle, and poison ivy.


When to Apply: 

  • Apply when dandelions, clover and other broadleaf weeds first appear in spring, summer or early fall. Do not apply when temperatures are over 85° Fahrenheit.
  • Spread in the morning while there’s still dew on the lawn, or after a light rain shower.
  • Only apply to lawns that have not been mowed for at least 48 hours. The particles need to cling to the leaves of the weeds for the herbicide to work.
  • Do not apply when seeding or under newly laid sod.


  • Use a rotary or drop lawn spreader.
  • Check to make sure the spreader opening at the bottom of the hopper is closed.
  • To select the proper spreader setting see the Spreader Settings Section in the accordion below.
  • Push the lever forward only when ready to spread.
  • Apply fertilizer around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow an overlap to avoid gaps in coverage.
  • Do not reseed the lawn for at least 2 weeks after application.

Post Application:

  • To avoid staining, sweep any excess fertilizer granules off of hard surfaces and back onto the lawn.
  • Do not mow the lawn for at least 72 hours after application to allow the weed control time to be absorbed.
  • Start irrigating the lawn 72 hours after application.
