Fertilizer!
One of my favorite ways to divert kitchen refuse from the landfill is by making homemade liquid fertilizer. We boiled eggs for breakfast one morning. I peeled the shells, returned them to the water I’d boiled them in, and poured the whole thing into the blender. To this, I added the morning’s spent coffee grounds and the chopped-up peel of the banana we’d shared. The eggshells provide calcium, phosphorus, and magnesium. The banana peels contribute potassium, and the coffee grounds give the plants a boost of nitrogen.
Hit the switch on the blender and let the concoction chop and mix for a bit. I split the whole business with rain barrel water to a ratio of 50/50 and give all my plants a cup or so, depending on the size of the pot. You can strain out the solids and add them to the garden or compost, but I just let them spill into the pot for the extra fertile goodness.
Another bonus in keeping food out of the kitchen garbage can is this practice mitigates bad smells and soggy garbage bins, and everybody gets a lovely breakfast plants included. Plus, I save on fertilizer. Now, there’s some winning.
