My Miltonia and Oncidium really like the coir mix, which I began using since last fall. However, my mix has coir and perlite. I didn't have charcoal at the time of repot last year. This time around, I have charcoal and will add granite grit or marble chips instead of perlite.
Mike, what do you use to cut your coir brick? Is a 1 1/2 inch cut enough for a 2-3 plants in 4" pots? I made a mistake of reconstituting a whole brick last time that I ended up wasting the left-over.
