Winter-rainfall, summer-dormant tuberous plants usually begin making a root system before putting up shoots. It's often triggered by the first good rain. I have a lot of South African winter rainfall bulbs. As soon as nights get cool I soak them once, then begin regular watering when shoots appear.

I have found that my terrestrial tubers don't do anything until they start getting watered lightly. Then once the shoots start to appear I kick up the watering so that they stay pretty damp. Applies to both European and Australian terrestrials. I find that my Pterostylis curta (the only Pterostyils that I have had much success with, have at least gotten survival from Pterostylis x furcillata seems to like the same pattern )has a shorter dormancy - I start watering lightly in early August and get a lot of growth by late September) The European and other Aussie ones I start watering lightly in mid- to late- October, when the nights start to cool off.
I heard an excellent talk by Gary Yong Gee (Five Cities Orchid Society, California central coast, on Zoom) . He said that in Australia many of the Pterostyls species (and lots of other beautiful terrestrial orchids) also are difficult to cultivate. So I don't feel so bad about my failures.

I have grown a good number of Asian, Australian, European, and South African tuberous terrestrial orchids to be able to provide the specific growth pattern for a fair number of species.
According to what I have observed, tuberous orchids grow their non-tuberous parts of the plant (shoots/leaves/roots) in a particular order and that order is the following:
1) shoots
2) leaves
3) roots
The tuberous parts form from their root system, so you are under a lot pressure to keep their root system healthy and intact.
As a side note, I learned how to grow epiphytic orchids through learning how to grow terrestrial tuberous ones. This is where I found out how crucial the root system is to ALL orchids’ well-being. Your long-term success of a particular species or hybrid depends on how well you keep their root systems healthy.

Notice the leaves are bigger than the roots on this Thelymitra rubra tuberoid that had broken dormancy

This Diuris drummondii has the same growth pattern.

Thelymitra frenchii is a late grower, but same growth pattern - shoot, leaves, roots.
