Drainage Comments
DRAINAGE: Gravel Small gravel in small pot< and large in large pots is good it can be disinfected first; an advantage in plastic pots is that it helps them stand upright. OIE85Nov-17 0
DRAINAGE: Of Potting Mixes A fiberglass screening layer cut to fit the inside bottom of a pot prevents most creatures from crawling in through the drainage holes. OIE86Sept. 0
DRAINAGE: Phalaenopsis Culture It is second in importance to adequate light; if a plant dies in the second or third year, lack of drainage and aeration of the roots is the cause; bark eventually breaks down and denies air to the roots but bark can last 18 to 24 months in good service; old bark can be used up to 207o with new to seed a new mix; use a soldering iron on a conventional pot to provide more drainage holes, up to eight or nine three-eighths inch holes.
