Disposal for households
Disposal requirements vary
Fertilizers with pesticides or herbicides, often called weed and feed, are accepted at hazardous waste collection sites.
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.
