    Anyone growing Paphiopedilums in NZ Tree Fern Fibers Successfully?

    @masaccio New Zealanders have had access to tree fern for about 5 years. I forgot to mention that all the tree fern is sustainably harvested under the auspices of our Ministry of Primary Industries. http://www.thecollectorsonlinemarket.com/treefern/treefern.pdf

    Anyone growing Paphiopedilums in NZ Tree Fern Fibers Successfully?

    I can't comment on the Guatemalian tree fern. It will be for a different species compared to what we use in NZ and such it will probably require different management. NZ tree fern is very 'fluffy' and works best if pack it into the pot lightly. If you compress it too much it may hold too much...

    Anyone growing Paphiopedilums in NZ Tree Fern Fibers Successfully?

    If you use a 100% NZ tree fern fibre you need to watch that you do not over water. I live in Auckland , New Zealand and in summer the watering interval would be between 4 to 7 days and for winter two to three weeks. The general rule of thumb is if in doubt , don't water.

    Root Structure P. armeniacum

    Root Structure P. armeniacum

    I repotted my P. armeniacum today and I noted a root structure that I have not seen before with paphs. Is this normal or is something else going on?

    Disa media

    I had a fair amount of success growing them in 100% tree fern fibre and using Dyna Gro Grow 7-9-5 + Pro-Tekt as a nutrient solution, both mixed at 1:3 000. Disa's do not like a lot of salt.

    Mealy bugs
