Things to do in September

  • Harvest potatoes when the tops die down. Store them in a dark location.

  • Protect tomatoes and/or pick green tomatoes and ripen indoors if frost threatens.

Question of the Week

I maintain a fairly productive compost pile that I use to replenish my raised beds each year. This year, I have a large number of plants (mainly squash and tomatoes) that have come up in beds where this compost was used. Someone told me that it might be dangerous to eat veggies from these seeds that I assume did not get completely broken down in the composting process. Maybe something to do with excessive nitrogen levels? Is this true, or are these veggies safe to eat?
