How To Prepare Your Garden for Winter

The term “Fall gardening” doesn’t mean sitting in a lawn chair and watching the stalks of your spent vegetable plants tip over. In fact, as the summer gardening season comes to a close, the work in your garden is far from over. The actions you take through the fall and into the winter months will have a huge impact on the success of next year’s garden! While many gardeners put some of these tasks off until the spring, you can get a big jump start on a lot of the prep work now, ensuring that by the time the next growing season comes around, you will be ready to plant, not prep.

Before you begin, however, there are a few things to consider. First and foremost, you need to be familiar with the regional needs of where you live and garden. That includes the average annual extreme minimum temperature, approximate depth of frost, as well as the first expected killing frost. To find this out, you can contact your local agriculture extension service or familiarize yourself with the needs of your area on the USDA website.

Chop, Cut, and Clean

Start winterizing your vegetable garden by removing spent stalks and other plant debris that may become a winter incubator for pests and diseases. Leave late growing crops like carrots, garlic, horseradish, leeks, parsnips, radishes and turnips for harvesting into winter, but chop off dormant perennial tops and used annuals like tomatoes and squash as well as pea and bean plants a few inches above ground level. If they are disease free, add these plant tops to your compost pile. If they are diseased, discard them separately. This is also a good time to pull weeds and invasive or unwanted plants. These should also be discarded in a covered trash container, not added to your compost.

Time to Till?

If you live in an area with mild winters, you may want to till the soil to turn the remaining organic plant matter into your garden soil and allow it to break down into natural compost over the winter. This can also help reduce pest troubles you might face in the spring by exposing insects that may be planning to overwinter in your planting areas.

Tilling in the autumn isn’t for everyone, however. If your growing zone has especially cold and bitter winters, it may be better to leave a layer of plant stubble on the surface of your soil to prevent erosion and protect the underlying soil. Furthermore, gardens which are planted on slopes may need to maintain as much vegetation as possible in the soil to prevent excessive erosion.

In large gardens, it’s recommended to till only about 3 of every 4 rows of plants. The remaining rows will provide a partial windbreak to prevent erosion during the dry weather of winter and also provide a little cover for beneficial garden wildlife.

Spread Mulch


Bare, unprotected soil is much more likely to suffer the effects of erosion than soil protected by a healthy layer of mulch. Furthermore, a good 3-4 inch layer of mulch can help enrich the soil by breaking down over the winter months and keeping the soil warm and moist (assuming you are in a mild climate).

In colder climates, mulch is particularly beneficial around newly planted perennials that have not yet had a chance to develop an extensive or well-established root system. A thick layer of mulch will keep the ground temperature consistent and prevent damaging freeze/thaw cycles in the fall that can disrupt the growing patterns of younger plants. I’d advise also checking the mulch in January and February to make sure it hasn’t thinned out too much due to winter winds and add more if necessary to protect against the same freeze/thaw cycles in the early spring months.
