Coir (coconut fiber) is a completely natural byproduct of the huge coconut growing industry of the island of Sri Lanka. Coir is an excellent growing medium for all kinds of containers and baskets. Improves other potting mixes when you blend them together. It retains plenty of moisture, but is very porous which allows for good air circulation and healthy root development of seedlings and cuttings. It is sterilized for freedom from weeds and plant pathogens.

This product is OMRI certified ORGANIC.

11 LB. SIZE! Compressed 5 to 1

Makes about 20 gallons.

If you are ordering 20 or more blocks, please call Customer Service at 1-800-733-4129 (M-F, 9-5 ET) for a freight quote.

    To maintain humidity level in plants, this is essential. Easy to break up for separate plantings and does a great job!

    Little bit cumbersome to re-hydrate but the resulting product is worth it.

    It's perfect!

    Posted by Penny Coleman on Apr 6th 2025

    After using coconut coir from a different source, I knew it was something for my garden. I shopped around, read the reviews and purchased the big block. It is a solid pc and it is large. I took the idea from one of the reviews and used a pry bar to chisel it into smaller sections to use easier. There is one direction that works better than the other. It has been just what I needed for my garden of raised beds and containers. I will purchase again.

    Best quality I've found

    Posted by Michael Kessler on Apr 6th 2025

    Better then the amazon products by a country mile, I just ordered 5 more Extra large. Even with the shipping charges and back order delay still worth it.

    Great addition to the garden soil and planter boxes

    While the picture was for a large block, it arrived in small brick sizes which turned out to be easily to use, storing the unused until need arises.
