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.
