Potting Mix For Orchids Buying Guide

Potting Mix For Orchids Buying Guide

And that was our list of the top 8 potting mixes for orchids. Have you decided on which one you want to get for your orchids?

Choosing the most suitable potting mix for your orchid plants is not as simple as it seems. So, if you are still confused after going through our list, we completely understand. With so many options available on the market, it is easy to become overwhelmed. Besides, you need to take into account different factors before making your final purchase.

That is why we have prepared this brief buyer’s guide for you. It contains some of the critical factors that you should consider before you buy a potting mix for your orchid plants.

So, if you want to know what these factors are, read on.

  1. Type Of Orchid

Before you buy an orchid soil mix, it is important to consider what type of orchid plants you have. Orchid plants have high diversity, due to which there are numerous types of orchids that exist, with the most common ones being phalaenopsis, cattleya, and dendrobium.

Each orchid type requires specific soil conditions to grow, without which they may wither or not bloom properly. That is why determining your orchid type is crucial before starting to look for a soil mix.

  1. Aeration

Ample aeration is vital to ensure the growth of your orchid. It prevents the roots from suffocating and provides sufficient room for the roots to expand in the soil.

In their native habitats, orchid plants can grow best in slightly dry soil. This can be facilitated through proper aeration. Furthermore, orchid roots can sometimes remain exposed, and an aerated soil aims to mimic that condition.

Materials such as perlite, charcoal, and tree barks facilitate aeration. So, you should look for these ingredients when choosing a potting mix.

  1. Drainage

Besides aeration, adequate drainage is another essential factor to consider. It is vital for the development of the plant, as suitable amounts of water are necessary for its growth. However, excessive water can be detrimental to the plant, as it increases the soil moisture and suffocates the roots. 

Therefore, it is important that the potting mix you choose has good drainage. It should be able to retain only the necessary amount of water while eliminating any excess. For this, you should look out for ingredients like perlite, charcoal, or sphagnum moss in the soil mix, as they help in drainage.

  1. Ingredients

The right soil ingredients can make all the difference in the development of an orchid plant. So, you should make sure that the soil mix contains all the necessary ingredients for its proper growth. 

Typically, most potting mixes come with ingredients such as charcoal, perlite, wood bark, or coconut husk. These help in the aeration and drainage of the soil. However, some potting mixes may include vermiculites, lava rocks, sphagnum moss, or fertilizers for better growth.
