What to Do Around the House This Week

September Household Checklist

• Book a furnace tune-up before the first cold week fills the calendar.
• Clean gutters after the first leaf drop and check that downspouts drain away from the foundation.
• Swap summer bedding for heavier blankets and wash the lighter set before storing it.

In Season at the Market

Produce that is typically in season across much of the country in September includes apples, grapes, pears, sweet potatoes and winter squash. Buying what is in season usually means better flavor and lower prices, so plan a few of this week's meals around it.
