In November, most of us will see our transition into winter, although many northern and high-altitude areas have already experienced a lot of snow. November is a cleanup month. It is a good time to fix up, clean up, and put away tools and get out the snowblower. It is a good month to reflect on how well the landscape and garden looked and produced this year. Take one last look at any fall color combinations so that you can change them next year if you want. Do not forget to take pictures.
For most of the country, except the Deep South and some coastal areas, this is the time of year when most plants go dormant. Clean up leaves, and add them to compost piles. Remove the tops of dying annuals and dormant perennials. Once they are gone, you can add bark mulch to the beds to stabilize the temperatures and to prevent frost action from heaving plants out of the ground.
