Potting Mixes

Orchids are easy plants to grow. The main problem the first time grower has is the wrong potting mix (medium). The first thing most orchids do not like to sit in water. Your type of pot, the medium used to pot along with your growing conditions will all play a part in having a happy plant

Here are some different types of medium used by orchid growers. Some mediums can be mixed together to help control your watering and conditions


Orchid Bark For Sale Orchid Bark Qld

Bark:- We use Debco or Aus-Grow orchid bark typically in a 25-50 Litre bags both are very similar products to use. Without going into types of bark of what we have tried and tested these are the best orchid barks available to us. There are also various sizes or grades of these barks

Mini Size Bark:- We use this only in our tubes (baby plants) mixed in with other mediums

Medium Size Bark:- We use this for smaller plants coming out of tubes or just a small growing size plant that may need a bit more moisture (smaller bark generally won't dry out as quick due to less airflow).

Large Size Bark:- We use this in lager sized orchid plants like Cymbidiums and mixed with medium size bark for cattleyas

Cork Mounts:- Used for mounting orchids/stags/elks Cork is the best mount as it lasts for years unlike tree fern etc....

Perlite:- There's a few different brands of perlite sold normally in 100 Litre bags we mostly use a coarse grade mix (approx 5mm in size)

Charcoal:- approx 10mm - 15mm in size is good 

Coconut Husk/Chip:- There's a few different brands of husk and what we have found one needs to be careful when buying, there can be big differences. Husk normally comes in a dry and compressed form and before you use, will need to soak to expand and hydrate. Some brands will need to be washed, this is more to remove unwanted salts. If you can try to get pre washed and PH ready. In uncovered growing areas never pot directly in chip we found when wet and rainy conditions over long periods (2-3weeks) it holds too much moisture and may rot your plants. A lot of growers use coconut husk/chip as it is a bit cheaper and also takes up less room in the shed being compressed. We don't use a lot of it due to the market of people we sell plants to. Most growers do not have a covered growing area therefore bark gives them a much greater success growing orchids when they get them home.

Peat:-  We only use Canadian peat moss this is used in a covered shade house on tube stock (baby) plants. Bag size is 60kg. I do know some growers that use a peat and perlite potting mix using typically 5x perlite to 1x peat and that's it. The main disadvantage for us is the pots are light and if your growing area is not well sheltered your beautiful pots might fall over etc... and it does not ship/travel real well.


Sphagnum Moss :- We use this on some tubes (baby) plants and Phalaenopsis orchids with great results. We now have a small 100g compressed Spag which when mixed with water makes a 300x120mm pot full, this is great for people that would like to just give it a go or need to pot just a few orchids also great for when tying orchids to the side of a tree to help hold a little moisture around the roots till it holds onto the tree itself.

Orchid Spag

Our all rounder general mix 1 bag of medium bark, 2 bags Large bark, 3/4 bucket (10Litre) coarse perlite, 1/4 bucket of charcoal

With this mix we water in winter once every 10 days and in the heat of summer every 2nd day and if we get over 5-10mm of rain this is counted as a watering


Happy Growing
