+1 for composting. There's something satisfying about putting down a deep, dark brown soil to grow some veges in. I don't grow a lot (peas and corn generally), but it's magnificent eating.

As a result of the composting, once my last winter crop of peas had died out, a bunch of mis-matched tomatoes began growing out of the same patch, so I left the trellis up and let the plants develop. Roma tomatoes, cherry tomatoes and regular tomatoes all growing haphazardly, totally unplanned. A most pleasant surprise that kept me in bruschetta for a few weeks :)

There's something soul satisfying about eating something from your own yard; must be a deep-seeded DNA/evolution thing, like the smell of a campfire.

Back to composting: it's amazing how small a volume of trash we throw out now that we're putting foodstuffs into compost.
