🌱 What if I See Fungi on My Bark?
Orchiata isn’t just a growing media – it’s a living environment. During the natural aging process, beneficial fungi become part of the bark’s microbial balance.
✔ Naturally Protective – fungi help shield roots and stems from harmful pathogens
✔ Healthy Root Zone – creates a balanced micro-ecosystem for stronger growth
✔ Rarely Visible – fungi are usually microscopic, though white mycelia may appear under the right conditions
These micro-organisms are not harmful – they’re part of what makes Orchiata unique, helping your plants thrive naturally.
