Is bark mulch biodegradable
Yes, bark mulch is entirely biodegradable, though the pace at which it melts back into the soil depends on tree species, particle size, rainfall and the secret labour of earth-dwelling organisms. Fungi begin the banquet by threading white filaments through each chip, unlocking lignin and cellulose. Woodlice follow, rasping the softened edges, while worms tug shreds down their burrows, mixing woody carbon with mineral soil. In warm, damp summers the change is hurried; in frosty, wind-scoured winters it slows to a patient, creaking whisper.
Decomposition never leaves the border bare overnight, so gardeners gain both appearance and gradual soil improvement. Fine grades can disappear within eighteen months, releasing a flush of humus that darkens the surface and steadies moisture loss. Chunkier nuggets linger three to four years, surrendering themselves in splintered stages before dissolving completely. As the layer thins, simply scatter fresh material over the top; there is no need to remove the residue because it is already part-compost, ready to nurture new roots. Choosing bark from AHS LTD guarantees pieces free from chemical preservatives, ensuring that breakdown yields only plant-friendly compounds.
The cycle is natural, silent, and endlessly reassuring.
