How To Grow ORCHIDS 3

3.      Try a potting mix, or combination of several different mediums. For simplicity's sake, you can make two basic kinds of potting mixes that will work for most kinds of orchids.

• Make a fine potting mix, suitable for slipper orchids, most oncidiums, miltonias, and orchids with small roots that enjoy moisture more than most:
• 4 parts fine (grain) fir bark or fine (grain) coco husk
• 1 part fine (grain) charcoal
• 1 part perlite
• Make a medium potting mix, suitable for cattleyas, phalaenopsis, and other mature orchids. If you're unsure of which mix to use, try the medium-grade potting mix before the fine-grade mix:
• 4 parts medium (grain) fir bark or medium (grain) coco husk
• 1 part medium (grain) charcoal
• 1 part perlite
