Does bark mulch stop soil compaction

Soil compaction is one of the hidden problems in many gardens, often caused by heavy rain, regular foot traffic or simply the natural settling of soil over time. Compacted soil reduces the amount of air and water that can penetrate, leaving roots struggling to grow and plants looking lacklustre. Bark mulch offers an effective way of helping to prevent this.

When applied as a surface layer, bark acts as a cushion. Raindrops that would normally strike bare soil and compress it are absorbed by the mulch instead, allowing the soil beneath to remain looser and more open. This protective layer also spreads the pressure from light footfall, reducing the chance of the ground becoming hard and impenetrable.

Over the longer term, the benefits continue as bark mulch decomposes. The gradual addition of organic matter improves soil texture, encouraging a crumbly structure that resists compaction naturally. Roots can spread more freely, earthworms can move with ease, and drainage is improved.

While no mulch will completely eliminate the risk of compaction in high-traffic areas, using bark mulch makes a clear difference in borders, beds and around trees. For those seeking high-quality bark for this purpose, AHS LTD provides a wide selection of suitable options.
