Coir

We've discussed this on the list a number of times. It needs to be
washed a number of times to get rid of the salts. I didn't look in the
archives, but I may have posted this in the past. On one of our trips to
South Africa we were helping Rod and Rachel Saunders with some pots.
These were blooming size bulbs, not seed, but to my surprise they were
potting them in a pure coir mix. Rod explained that bulbs grew really
well in this mix, but you did need to be sure that the coir had been
prewashed to rid it of salts and you needed to fertilize as there
wouldn't be in nutrients in the mix. I've never tried it, but thought it
interesting.

By the way, when Gastil was helping us with the wiki she created some
wonderful wiki pages including this one:
