David, if you do decide to plant your Araucaria out, drape a light
shade cloth/net over it for a week. Then in week two, remove it in
late afternoon, replacing it in the morning. After that, the risk of
sun scorch will be almost nil and the worst you will see is a light
bronzing of the youngest shoots. Wind protection is important, since
the plant cannot withstand the full force of the bitter winds that have
come to characterise late winter in recent years.
