Chopped Fernwood Tree Fern Fibre is used as a plant growing substrate. It is used to grow many plants such as orchids, aroids, hoya and many other pot plants.
It is a universal application and can be used for rooting and growing cuttings and plants through all their growth phases. It can be mixed with other substrates such as bark, pumice, perlite and charcoal.
Tree Fern Fibre has a very large surface area resulting from having a very fibrous hairy form. This gives it unique properties when used as or in a potting mix.
- Due to tree fern fibre having a large surface area, there is increased contact between the roots and the fibres, which allows for the efficient delivery of water and nutrients to the root system.
- Tree fern fibre will absorb moisture without it becoming boggy.
- Because all the tree fern fibres are connected, water is distributed fairly evenly through the tree fern fibre due to capillary action, which also improves the availability of nutrients.
- For many substrates like bark, the moisture will be found in the middle section of the pot because the top and the bottom dry out first. The capillary of tree fern fibre allows the fibre to dry out evenly.
- Tree fern fibre is very durable and takes years to break down. I have read reports of orchids repotted after 15 years, and the fibre had not broken down.
Tips for using tree fern fibre.
- Beware of overwatering. Overwatering may result in your roots rotting.
- Fernwood Tree Fern Fibre has excellent moisture retention properties, so you do not have to water your plants as regularly as you would with other substrates.
- It may be that during the warm summer months, you may only need to water once a week and in the cool winter months, once a month.
- Before watering, check the moisture content of the tree fern fibre inside the pot.
- Let the tree fern fibre dry out a bit before watering. The substrate will turn from a dark brown to a lighter brown as it dries out.
- Plants growing in tree fern may require less fertiliser when compared to plants growing in other potting substrates. It is hypothesised that tree fern may have lower populations of nitrogen-consuming bacteria. This means that you should be able to use less fertiliser for tree fern-based substrates.
- If your plants are producing long floppy growths, then this is an indication that you need to reduce the amount of fertiliser you are using.
Fernwood Tree Fern Fibre is packed in 5, 10 and 40-litre bags.
