Coconut husk chips are a popular and sustainable potting medium for orchids. They can be purchased online or locally, and the husk is soaked overnight in water to ensure proper moisture retention. The best potting medium for orchids is one specifically formulated for them, such as fir bark, sphagnum moss, peat moss, lava rocks, perlite, charcoal, clay pebbles, tree ferns, or coconut fiber.
To make a finer potting mix for your orchid, add 4-parts fir bark or fine grade coconut. If you don’t have these, you can use a mix of fir bark, sphagnum moss, peat moss, lava rocks, perlite, charcoal, clay pebbles, tree ferns, or coconut fiber. For Terrestrial orchids, a denser mix like sand and sphagnum moss or coco peat works best. Peanut shells can also be added to the mixture for good airflow.
Orchid potting mix typically consists of pieces of bark, moss, perlite, charcoal, tree fiber, or coconut fiber. The contents will vary according to the manufacturer, but medium-grade potting media is generally recommended. Before using coconut husk, soak it in water to cause it to swell enormously in volume. Use a container of 10 liters or more for a 3 liters packet of coconut husk and fill it with 10 liters of water.
Coco husk has been rinsed in sea water, so rinse it carefully before use with plants. If you can find coir sold in chunks, that may be an option. Place the orchids on the husk and secure it using a piece of wire. Coconut acts as a water absorbent, making it comfortable for the orchids’ roots.
