Using Wet, Clumped Fertilizer: Absorb with Cat Litter, Don't Make Tea

Wet, dissolved 10-10-10 is too concentrated for compost tea—it will burn plants. Instead, mix in cat litter to absorb liquid, then broadcast the damp granules lightly under shrubs and trees. Wear gloves. The nutrients are still good; just apply as a slow-release solid.

Fertilizer doesn't expire, but concentration matters.
