September is the month to…

  • Harvest and dry herbs while they are at their peak. If you have been gathering perennial herbs regularly through the summer, mid September should be the last cut of the year. Any new growth after that will likely be damaged by cold weather. The drier days of autumn are a good time for drying herbs. Get some hints on drying garden produce from our video “How to Dry Vegetables.”
  • Remove plant debris and weeds from the garden to reduce the number of overwintering sites for unwanted insect and disease populations, and minimize the deposit of seeds into the soil “weed seed bank.” Follow with a cover crop to protect the soil and serve as competition for weeds. If planting a cover crop is not an option, topdress with an organic mulch, such as seaweed, straw or leaves. Mulch will also add nutrients to the soil and improve soil structure.
  • Watch the weather and take steps to protect tender plants if there’s a chance of frost. Bulletin #2752, Extending the Garden Season describes methods to protect plants from the cold and extend the growing season.
