I’ve a Wollemi Pine about 4 years old now. It grew very well in the first two years. Last winter’s frost seems to have killed it, as the stems went brown and fell off quite easily. The winter before that the tip of the plant died (no wax polar cap formed), so I pruned it off and new growth appeared the following spring, just below where I cut it. This year I think frost has killed it. Not sure what to do now or how can I know if it’s actually dead. Could this also be a fungicide problem?
It is not completely hardy below -5 degrees Celsius. Older trees might survive lower temperatures but young trees can be killed.
Leave it for a couple of months at least and see what happens. Nothing to do otherwise.Â
