Disposal requirements vary

Fertilizers with pesticides or herbicides, often called weed and feed, are accepted at hazardous waste collection sites.

  • All containers must be 5 gallons or less
  • Total waste limit: 50 gallons per trip
  • Professional grade fertilizers are not accepted

Solid fertilizers with no pesticides can go in the garbage. Liquid fertilizers with no pesticides can be solidified using dirt, kitty litter, paper towels, or other absorbent materials and put in the garbage.

Dry, empty containers, including aerosol cans, can go in the garbage (no need to rinse). Do not recycle fertilizer containers.
