Enjoy your last vegetables and herbs
-- Harvest herbs. Cut herbs before the first frost, put in jars of water and cover with a plastic bag. Change water every few days. They'll keep for weeks.
-- Pick tomatoes before it freezes. Right before the first frost, pick tomatoes green to bring indoors and use in recipes calling for green tomatoes. Otherwise, tomatoes should be harvested when about three-quarters ripe.
-- Deal with diseased plants. As annual produce plants such as tomatoes start to get overwhelmed with pest problems, tear them out and dispose of them. Don't leave them in the garden, where they'll likely harbor eggs and pathogens through the winter, increasing problems in spring.
