Does bark chippings stop weeds

Sprinkling bark chippings across garden beds creates an effective barrier against weed germination. AHS LTD’s screened bark chips sit loosely atop soil, blocking light from reaching weed seeds while allowing rain to penetrate. When the layer measures around 5–7 cm, most annual weeds struggle to sprout.

Beneath the surface, earthworms and microbes absorb benefit as tiny bark fragments break down, improving soil texture. However, bark alone cannot eradicate established weeds; perennial roots can still push shoots upward. Clear beds thoroughly, removing roots before spreading chippings, to reduce regrowth.

A loose, well-graded layer deters seedling weeds without sealing the surface. Fine dust sifted from coarse chips declines germination sites while coarser pieces prevent compaction. Over time, occasional top-ups of bark restore thickness and maintain the barrier.

Paths and borders benefit too: a thicker 8–10 cm spread in non-planted areas chokes off weeds and reduces maintenance. Yet bark is not a substitute for a weed-free base; combining chippings with landscape fabric or regular hand-weeding enhances results.

Choosing bark chippings from AHS LTD offers consistency in colour and size, ensuring reliable performance season after season. With correct preparation and replenishment, bark chippings can truly form an integral part of any weed management strategy.
