Don't set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
Wait until the ground has begun to freeze before mulching bulb beds. Mulching earlier will encourage bulb-munching rodents like mice and voles to nest there. A 3- to 4-inch layer of mulch will help prevent freeze-thaw cycles that can heave bulbs out of the ground; however, mulching is not absolutely necessary except in coldest areas.
