Reuse
If the pesticide, herbicide of fertilizer is in good condition, try to find a neighbor, friend, or family member that could make good use of it.

Disposal
Granular (dry) fertilizer can go in your normal trash. However, make sure that it is just fertilizer and does not contain any pesticides or herbicides, such as in a "feed and weed"-type fertilizer. Unused pesticides, herbicides and liquid fertilizers should be safely stored until the next local Household Hazardous Waste (HHW) Collection Day in your area. In the City of Houston, the Department of Solid Waste Management has HHW Collection Days every 3-4 months. Contact the HHW Information Line at 713.551.7355 for more details.
