Winter pine mulch


Bark mulch does a lot of great things for your plants during the spring, summer and fall: It blocks weeds, holds in moisture and moderates soil temperature. That may not sound as important during the winter when your garden plants are absent or dormant, but you may be surprised by all the benefits mulch still brings during the snow even when there are no plants above ground.

It’s best to put down a thick layer of mulch, 3 to 4 inches, once all of your plants have completed their life cycle for the fall season or when you see the first signs of frost. Make it a little thicker than you do during the rest of the year and remove some of it in the spring when you believe you’ve seen the last frost of the season. Otherwise, you will have a too-thick mulch layer during warm weather that will trap in too much moisture.

The major advantages of having a thick winter layer of mulch are as follows:


Protect your plants

Perennial plants, along with some roots that lurk near the surface, need protection from the cold. The bark mulch provides a thick layer, like a winter coat, to keep crowns and exposed roots from contacting snow and ice and provides insulation from the low temperatures.


Preserve the soil

The mulch doesn’t just block cold temperatures, but warm temperatures as well. If the soil temperature is allowed to rise and fall continuously, the freezing and thawing will lead to frost heaves and loosen the grip roots have on the soil. Without mulch, it could even wear away the top layer of soil and expose roots to the cold air. This erosion can easily be avoided by capping the soil with mulch.


Prevent drying

The harsh winds and temperatures can dry out shrubs and other plants, causing desiccation and wilting. Mulch’s ability to keep moisture in the soil is a year-round advantage, but remember to whittle down the thickness of the mulch when winter ends by removing some of the material. Otherwise, you risk trapping too much moisture inside and creating a nesting area for insects.
