Time to start cleaning your gardens. As annuals and most vegetables reach the end of their productive life, cut them down and add the healthy material to the compost bin. Any diseased (for example, downy mildew) or insect-infested material should be bagged and placed in the trash. All garden weeds should be pulled now and bagged (and definitely not composted), chopped or otherwise made incapable of growing. Left in place, the weeds will produce thousands of seeds in your lawn and garden, making your job much more difficult next year.
