An amazing product which we started using during the pink bark shortage and we were completely blown away by the results. Absolutely fantastic for orchids and aroids as it is both water retentive but also allows a huge amount of air to circulate around the roots. Tree Fern fiber can be used straight out of the bag of blended into your existing mix. This product is supplied to us by the premium distributor of New Zealand Tree Fern. It is completely natural and NEVER treated with any chemical whatsoever. It is also sustainably harvested which was of utmost importance to us while sourcing. The biggest complaint we had when we started using it was all the large fibrous chunky tree fern which made repotting so much harder than it needed to be, so we remove all the debris and chunks for you.
