By laying bark mulch on your soil, you do the same thing — you protect your plants’ delicate roots from excessive heat and drought in summer, and help them resist alternate freezing and thawing through the winter. With bark mulch you also help improve your soil’s texture by enriching it with natural humus.

Does bark chippings improve soil?

Organic mulches include bark chippings, shredded bark, wood chippings, wood shavings and compost. These materials retain soil moisture, regulate soil temperature, and suppress weeds. As they naturally decompose, they also release a range of nutrients that enrich the soil and enhance its fertility.
