About a week after applying humanure around the base of our kiwi plants, I figured out a minor flaw --- the compost is chock full of tomato seeds.  When I cook tomatoes into soups and sauces, I leave the skins and seeds in, and apparently the human digestive tract doesn't bother the seeds at all.  Since tomatoes are a large proportion of our winter diet, the result is a forest of seedlings everywhere I laid down humanure in the garden.

I'll let all of the tomato seeds sprout, then if they seem to be growing too fast, I'll let Mark whack them down with the weedeater.  In future, it might be smart to apply humanure just a few weeks before the first frost --- long enough to get the seeds to sprout before winter naturally kills them off.
