It might have to do with a soil organism that is lacking in the US. There is quite a lot of information about this with a simple google:

A complex community of microorganisms lives within and alongside wollemi pines.The moist microclimate that shelters the trees promotes symbiotic associations with several spe-cies of endophytic and mycorrhizal fungi. The former live between the plant’s own cells in theleaves and stems. There, some types produce chemical compounds that help protect the plantfrom pathogens. One such substance is paclitaxel, an important anti-cancer drug that is currentlyharvested from the rare Pacific Yew and sold as Taxol in North America. Mycorrhizal fungi live inand among root cells and send projections out into the soil, where they aid nutrient absorption.

protect 2 of your rostratas and leave the 3rd unprotected
Might do that, Tim.
Tough to choose which one to sacrifice 😆
marceli, that's a big specimen at the zoo, wow.
Did the zoo have it locked inside a steel cage when it arrived?
Seems most the botanic gardens did that.
Part of the hype.

Interesting info, Jesse.
The botanists will figure that out in no time.

Barb, I found it by accident. Will try to check someday in spring if it's still there.

I hope the zoo realizes the value of that specimen and looks after it.
Megabucks, but probably a donation.
