Recycling & Disposal Information:
Dry, granular fertilizer that does not contain pesticides may be placed in the garbage.
Liquid fertilizer (or plant food) that doesn’t contain herbicides, pesticides or insecticides may be poured down your sink as long as it flows into a sanitary sewer and not a septic system.
Bring fertilizer with pesticides to your county's household hazardous waste collection site.
After applying fertilizer, sweep up granules from hard surfaces like driveways and sidewalks to keep them out of storm sewers and nearby water. Apply the sweepings to your lawn or garden.
