coir in sqare foot gardening

rita_from_mb(2b-3)February 3, 2009

The perfect growing medium according to Mel for square foot gardening is 1/3 peat moss, 1/3 coarse vermiculite, and 1/3 compost. Has anyone ever used Coir instead of the peat moss? It is more environmentally friendly and compacted squares are easier to buy and put into the trunk.

I too want the answer to this. I also want to add that since PVC is toxic and environmentally so reprehensible that it has been banned outright in certain European nations, instead of using PVC pipe for the supports for row covers on the boxes as Mel suggests, I found that PEX (crossed polyethylene) pipe does the same job, and is cheap and readily available at Home Depot, and much much less damaging to the world, in its production and endcycle.

So, coir instead of peat, and PEX instead of PVC.
Nuff said.

Hi Rita - I haven't tried coir, but I just tweeted Mel about this, and he actually tweeted back! (Okay, maybe it was someone helping him!) Anyway, he referred me to his blog where he points out peat is different than peat MOSS - and peat moss IS environmentally friendly! Here's the link to his blog page:

Here is a link that might be useful: Mel's blog on peat

I have used coir in container gardening and completely believe in it now. I would recommend not using as much vermiculite and adding perlite. coir holds moister but not too much water .... if you get that.

It is by-product of coconut shells. Recycled coconut fiber. I believe they take the shells once a company is done with what they need for the insides, like shredded coconut for example, and shred it and put it in compressed bricks. You rehydrate it and it fluffs up nicely. Definitely have to mix it with compost or potting soil. This is my second year using it and I like it.
