Early October is a good time to plan for and work on your vegetable beds. Simply leaving them to go through the winter months without your care can result in disappointment come springtime. It’s just about time to put your beds “to bed.”

YOUR GARDEN BED IS EMPTY — NOW WHAT?

When tomatoes, cucumbers, beans or other summer crops finish early, don’t assume that garden space has to sit empty until next spring. September gives gardeners an opportunity to clean up the bed, improve the soil and possibly grow another crop.

1. Pull up the finished vegetable plants and remove weeds, fallen produce and other debris. If plants were heavily diseased, remove that material rather than leaving it in the bed. Don’t put it into the compost pile.

2. Look at the soil. If the bed would benefit from additional organic matter, top-dress it with finished compost.

3. If your growing season allows, plant again! Quick-growing and cool-season vegetables such as radishes, lettuce, arugula, spinach, bok choy, green onions and some varieties of kale may be possibilities depending on your location.

4. Another option to improve and protect the soil is to plant a cover crop of oats, rye, clover, field peas and/or tillage radishes. Seed packets may be available in your local garden shop.

5. If there isn’t enough time for another crop, or you simply don’t want to plant again, protect the bed instead. Covering exposed soil with an appropriate organic mulch can reduce erosion, suppress weeds and help conserve moisture.
