CONSIDER LOCATION. If your main composter or heap is across the yard, make it easier over the winter and get a secondary compost bin. Keep your secondary bin easy to access.
CONSIDER SIZE. Keeping a large secondary compost is great BUT. Once it's full it can be a bear to move. We use a 5 gallon bucket. It's big enough to hold 2-3 weeks worth of scraps and small enough to carry to our pile when necessary.
DIG IT: no, really. Sweep the snow out of the way till you find your last compost additions.
FILL IT UP! Empty your secondary compost bucket on top of previous additions.
BURY IT: Once the scraps are added to the pile, recover it with snow.
DON'T STOP!! Keep on composting to keep those food scraps and waste paper out of landfills, and turn it into healthy soil for use in your own planters, garden and more. .
