All About Cultivating Cattleya Orchids: Substrates, Organic and Inorganic Media, and Mounting Options

Cattleya orchids are one of the most popular and beloved orchids among growers and enthusiasts worldwide. Known for their large, colorful, and fragrant flowers, cattleya orchids are a joy to cultivate and watch as they bloom. In this blog post, we'll explore the different options for cultivating cattleya orchids, including substrate media, organic and inorganic media, and mounting options for epiphyte orchids.

Substrate Media for Cattleya Orchids

Substrate media is a common method for growing cattleya orchids. The substrate is a material that serves as a growing medium for the orchid roots. It should be well-draining, allowing water to flow through but also retain enough moisture to keep the roots hydrated. Some of the commonly used substrates for cattleya orchids include:

Bark: Bark is a popular substrate media for cattleya orchids. It is made from the outer bark of trees and provides good aeration and drainage for the roots. Cattleyas grow well in a mix of medium-grade bark and coarse-grade bark.

Coconut Coir: Coconut coir is a renewable and environmentally friendly substrate media that is gaining popularity among growers. It is made from the husks of coconuts and is known for its water-holding capacity, making it ideal for orchids that require a lot of moisture.

Perlite: Perlite is a volcanic rock that is lightweight and porous. It is commonly used as an additive to improve aeration and drainage in substrate mixes.

Organic and Inorganic Media for Cattleya Orchids

Organic and inorganic media are another option for growing cattleya orchids. Organic media is derived from natural sources like bark, coconut coir, and sphagnum moss. Inorganic media, on the other hand, is made from materials like perlite, vermiculite, and lava rock.

Organic media provides more nutrients to the orchid roots, but it can also break down faster and become soggy. Inorganic media, on the other hand, lasts longer but doesn't provide as many nutrients.

Mounting Options for Epiphyte Orchids

Epiphyte orchids like cattleyas grow on trees in their natural habitat. To mimic their natural environment, growers can mount their cattleya orchids on a variety of materials like cork, tree fern, and driftwood. The mounting material should be able to hold the orchid securely in place and provide good air circulation.


In conclusion, cultivating cattleya orchids can be a rewarding and enjoyable experience. Choosing the right substrate media or organic/inorganic media and mounting options can make a significant difference in the growth and health of your orchid. Whether you choose to grow your cattleyas in substrate or mount them, make sure to provide them with the right amount of water, light, and fertilizer to ensure they thrive and bloom for years to come.
