This extra large coconut coir brick is a convenient, high-value growing medium for all kinds of planting and gardening projects. Made from coco fiber, a completely natural byproduct of the huge coconut growing industry from Sri Lanka, this compressed coco brick expands quickly with water to create a loose, moisture-retentive medium that supports healthy root growth and strong early development for a wide range of plants.

Ideal for containers, hanging baskets, raised beds, seed starting, and cuttings, these coco coir bricks help improve drainage while still holding the moisture roots need. Use this coconut coir brick on its own for certain applications or blend it with compost, potting mix, or other amendments to create a lighter, more workable medium for planting. It is especially useful when you want a clean, easy-to-store option for container gardening and soil mixing.

Because coir is porous, it promotes good air circulation around roots while helping reduce compaction. This makes it an excellent choice for gardeners looking for a dependable coconut brick soil ingredient for seedling mixes, container arrangements, and general garden use. It is weed free, 100% natural, and supports healthy growing conditions for all kinds of plants.

This 11 lb. compressed block expands approximately 5 to 1 and makes about 20 gallons. Whether you are refreshing containers, filling raised beds, rooting cuttings, or preparing soil for new plants, this extra large coco coir brick is an easy, practical addition to your gardening supplies.

    I love this stuff, and I love supporting an actual gardening company rather than Amazon. This coco coir has totally changed the gardening game for me and this is the best price around. They shipped it super fast, too! 10/10

    Coco Fiber Brick

    This was by far the best deal for this amount of product! It was shipped promptly and arrived in perfect condition. Used originally for repotting Monstera Deliciosa but will likely use for future plant propagation as well. Happy to support a local, Pennsylvanian company by purchasing through Kinsman Garden!

    I't hard to review this item as I haven't used it yet. I can say it was a fair price. I do look forward to seeing how it does and if it works well I will buy more. This is why I am giving it four stars for now.

    Simply The Best!

    Posted by Eileen Kennard on May 22nd 2018

    After 10 years, I had to replace all of my hay rack liners, soil & content, of course. Adding the coconut brick to the potting soil was so beneficial. Made it go further & added much needed moisture to the mix! Best decision I ever made! Great product!!!
