FAQs
Is Orchiata 3-6mm suitable for all orchid types? Yes, it's especially suited for young orchids and seedlings, but can also be used for small species or those requiring higher moisture control.
Do I need to rinse Orchiata bark before using it? No, it is ready to use straight from the bag with no flushing or preparation required.
How long does it last in pots? Orchiata is aged, not composted, so it won’t break down in your pots and can last for several years without needing replacement.
Can this be mixed with other growing media? Yes, Orchiata blends well with sphagnum moss, perlite, or other media depending on your specific plant needs.
Is it environmentally safe? Absolutely. It’s made from a renewable, sustainably managed resource and is 100% natural and organic.
What if I see white fungi in the bag? That’s normal. These are typically Penicillium or Paecilomyces fungi and are beneficial, helping to prevent harmful fungal growth.
I was so happy to find a smaller diameter of bark for my orchids. What I can get from retail suppliers like hardware or gardening stores is too large for my Phalaenopsis orchids. I am so glad I found Dr Greenthumbs and also pleased with the ease of ordering and the time it took to get my order to me.

Exactly what I needed!
After trying to find bark that wasn’t premixed with other substrates I stumbled upon Dr Greenthumbs and it’s now my go to! This bark was exactly what I was looking for, and the shipping was super quick (and also the cheapest of many other options). Can’t recommend enough :)
Great value and ease with combined perlite and vermiculite. For reference this is quite a fine / small grade mix, and I’ll be using in a mix for smaller seedlings rather than larger or more established plants.
