The best potting mix for orchids is one that provides excellent drainage and aeration while retaining some moisture.
Orchids should not be planted in traditional soil, as it retains too much moisture and can lead to root rot. Instead, opt for a soilless orchid potting medium.
Common ingredients include fir bark, coconut husk, sphagnum moss, perlite, and charcoal.
A basic mix might consist of coarse perlite, fir bark, and sphagnum moss, which promotes good air circulation and drainage.
The type of bark used can vary depending on the orchid species; for example, Phalaenopsis orchids thrive in coarse bark, while Cattleyas prefer medium bark. Additionally, young orchids benefit from fine bark.
For those looking to create a DIY mix, a combination of one part grounded tree bark, one-fifth part perlite or peat moss, and optional charcoal can work well
This mixture ensures that the roots receive the necessary air and moisture without becoming waterlogged, promoting healthy growth and blooming.
