Martins Pine Bark Coarse Mulch (approximately 10mm pieces) is a rich, natural‑brown hardwood bark mulch that retains its colour and aesthetic appeal. It’s ideal for mulching garden beds, pots, trees, and shrubs, where it acts as an effective protective barrier that conserves soil moisture, suppresses weed growth, and regulates soil temperature by reducing evaporation. As it slowly breaks down, it enriches soil structure and nutrient content. This long‑lasting, odourless, and safe-to-use mulch also offers insulation, shielding plant roots from extreme heat or cold.
