Our composted fine mulch is made from wood that has gone through the composting process, so that any potential weed s
fine-composted-mulcheed 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.

Tank’s Green Stuff’s Decorative Wood Chips are made from trimmings of mesquite, palo verde, pine, eucalyptus and other trees. These wood chips are 100% natural, made without color additives or chemical dyes. This beautiful recycled material has a rich blend of browns, light tans, and subtle reds throughout. The wood chips are ideal for mulching around trees to conserve water and keep the root-zone cool in the summer and warm in the winter. Wood chips make a great topdressing for a perennial bed or planter. They should also be used for rain water harvesting basins or berms, to control soil erosion and reduce evaporation. Wood chip mulch fosters beneficial soil microorganisms, and provides the soil with organic matter as the wood decomposes over time.
The wood chips are available in two sizes: 3″ and 1/2″. When applied to rainwater harvesting areas, the Large 3″ size is perfect for areas that experience moving water. The Small 1/2″ and minus size is great for basins and inside berms to retain moisture and reduce evaporation.

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.
