Orchid Potting Mix

Orchid Potting Mix

Orchid Potting Mix supports orchids that naturally grow with exposed, air-loving roots. In a pot, the bark pieces create spaces where roots can breathe between waterings.

Construction notes

• Bark structure: keeps large pores around roots
• Fast drainage: prevents a heavy soil mass around the crown
• Epiphytic orchids: suited to many pot-grown orchids with aerial-root habits
• Not terrestrial: not the right texture for orchids needing finer, soil-like media

Key details

Old orchid bark eventually breaks down into a finer, wetter material. Repotting into fresh mix restores pore space and gives roots a cleaner physical structure.

More to know

Many Phalaenopsis and similar orchids suit bark-led media, but terrestrial orchids may need a different substrate. Match the mix to the orchid’s root habit.

Using a bark-dominant orchid mix

Choose a well-ventilated orchid pot with drainage holes, keep the growing crown clear of the medium and settle bark between the roots without packing it tightly. Water when the roots and bark have dried sufficiently for the particular orchid.

Extra notes

• Moisten dry components before potting so the mix settles evenly.
• Choose pot size for the root ball, not for the top growth.
• Top-dress with the same mix to reduce surface compaction.
