Our composted fine mulch is made from wood that has gone through the composting process, so that any potential weed seed is eliminated. It is then ground finely to make an excellent ground cover around delicate plants in the garden or landscape. Perfect for flower and vegetable beds, or in pots for a decorative and effective mulch. Mulch conserves water and controls erosion while adding organic matter for good soil nutrition, and reduces evaporation. It keeps the soil cool in the summer, and warm in the winter.

Coconut coir (pronounced ‘koy-er’) is a sustainable alternative to peat moss. Coconut husk is a renewable resource with several advantages over peat moss. It holds water without compressing and absorbs water evenly, providing excellent root zone aeration and savings on water bills. Coconut husk products also have a more neutral pH (5.5-6.2), and can remain effective for up to 4-5 years. Coconut husk is an excellent way to increase the aeration and water-absorbing power of potting soil and clay or heavy soils, without peat moss.

Our OMRI-listed coco husk products are widely used for hydroponics, organic soil mixes, landscaping and container planting. Coco coir and coco chips can be mixed in different ratios (and amended with pumice, vermiculite, fertilizers etc) to provide the perfect planting medium for your plants.

Coconut husk products are also ideal for landscaping projects. Preparing an area for landscaping is a critical task. Coconut coir can be used as top soil or can be mixed with sand (60% coco coir, 30% sand, 10% compost) to use as a direct medium on open land, to grow grass, flowers, bushes, etc. Due to the water holding capacity of the coco husk, you can reduce irrigation drastically and grow healthier landscapes.
