Potted tubers Two-legged tuber
Flower in spring
What’s happening in the Grow Local nursery? The new propagation experiment for ground orchids is underway.
All you can see at present is a number of pots with white tags, but under there
are the dormant tubers waiting for autumn to sprout forth their new leaves.
Native terrestrial orchids are topsy-turvy in their growing - being dormant in
summer. I have to be careful to give them minimal water during this time. At a
time when all other plants are at their maximum water usage, these little fella’s
need very little. It’s hard to walk past without watering.
The trial is to increase the population of Diuris tricolor, a Donkey Orchid. This
is classed as a vulnerable species and any new tubers will eventually go back
in the ground near where they were collected or on nearby offsets.
Terrestrial orchids have a symbiotic relationship with
micorrhyzal fungi, so I have to add a little original soil from
the site to introduce the correct fungi to the potting mix.
