Mulching for Winter

For those gardeners living in a warm climate zone, mulching for winter isn’t a necessary part of your fall landscape routine, but for individuals living in colder climate zones mulching for winter can mean the survival of less hardy plants. Of course in warmer climate zones, many flowering plants will remain active throughout the year, but in colder climate zones these plants will become dormant. Unfortunately, for weaker plants, when the frost begins to hit the ground, the cold temperatures can have a similar affect as it would if these plants were above ground.

There is also a fine line between too little and too much mulch when mulching for winter. If plants’ roots are warm enough then they will begin to bud again, which would inevitably kill the plants. The main goal in mulching for winter is simply to apply a thin layer of mulch that will keep fragile plants protected from extremely cold temperatures in the middle winter months.

Other reasons for mulching include keeping plant roots from being pushed towards the ground, a process called heaving. Extreme temperature changes often cause this to occur, which may mean damaging roots of fragile plants. Mulching also means less weeds in the early spring months when a great deal of rain can cause extremely rapid weed growth. Mulching also helps to provide some beauty for winter landscapes and provides continuity to the remaining garden plants.

Alternative to a Greenhouse

Mulching for winter can also be an alternative to placing plants in a greenhouse, but this should only be done if plants are bulbs or perennials that would be able to survive at least freezing temperatures. Remember that even with a layer of mulch applied, the ground temperature will still reach freezing, so mulching for winter should only be done on those that can tolerate cold weather conditions, but just may be a bit less hardy than others.

Although you may think mulching for winter should happen in the late summer or early fall months, it is actually best to wait to mulch until after the first frost. This is because mulching too early can mean suffocating plants that are still alive or reversing the dormant process that begins to take place in the fall months.

Once the first few frosts have occurred and continue to occur, it is alright to go ahead and apply a thin layer of compost, usually made up of leftover grass and leaf clippings or even kitchen scrapes that are decomposed. This will help to insulate the soil and provide the roots and plants with nutrients. From here, apply only a thin layer of mulch, approximately 2-4 inches. Mulching for winter can include mulch products purchased at a lawn and garden store, such as wood chips, but it can also be products found at home such as pine needles or hay and straw.

Removing mulch in Spring

Keep in mind that it is essential to remove the mulch early enough in the spring that the plants will not be suffocated or kept from coming out of their dormant state. Just as mulching for winter means waiting until the first few frosts occur, remove winter mulch once the temperatures are regularly over freezing at nighttime.
Remember that not all plants need to be mulched for the winter, although a thin layer of mulch should be alright for all your garden plants. It is best to spend time researching whether your specific plants and flowers need mulching for winter before taking the time to protect your plants.
