What to Do Around the House This Week

1. Get the heat ready for Saturday night: a low near 40°F is the kind of night that reveals a weak furnace. Run the system for 15 minutes on a mild afternoon first, and bring in potted herbs or cover them.
2. Work around the wet days: the chance of rain or snow reaches 50 percent or more on Thursday and Friday. Set a boot tray and a second doormat at the entry and make sure basement window wells are clear, and save line-drying and yard work for Saturday, Sunday and Monday.

October Household Checklist

• Drain and store garden hoses, and shut off outdoor water lines before the first hard freeze.
• Test the heating system on a mild day so any repair is not an emergency call.
• Reverse ceiling fans to spin clockwise on low to push warm air down.

In Season at the Market

Produce that is typically in season across much of the country in October includes apples, pumpkins, pears, cranberries and brussels sprouts. Buying what is in season usually means better flavor and lower prices, so plan a few of this week's meals around it.
