Inspect houseplants that have been outdoors for insects and prepare to bring them in. Some can tolerate cool temperatures better than others and bring them in accordingly. Once placed inside, plants will adjust to lower light levels by dropping lower leaves. On Ficus (fig), leaf drop due to temperature changes can be dramatic, but is normal. Decrease the amount of fertilizer and water provided in late fall and early winter months.
Keep a close watch over your garden for any sign of pests so that you can move quickly and take action before the problem spreads out of control. On roses especially, keep an eye out for aphids and mildew. This is also a good time to reapply pepper wax or whatever you might be using to keep the deer, rabbits and other big pests away too.
Find out if you have a thatch problem: Dig down into your grass. A little thatch is good for your lawn. Thatch is a layer of roots and lower shoots that forms between the soil surface and the green vegetation If you find a brown mat, a half-inch thick or more, your lawn definitely needs de-thatching. That thick layer blocks water and air from getting down to the soil. It can also harbor insects and diseases. A tow-behind dethatcher will make the job of de-thatching faster and easier.
