How easy are they to grow? Santalums are root parasites aren't they?
Yes they are. Not that difficult once germination has been mastered, as they are not particularly fussy as to the host species.
Do you sprout the seeds and plant them in with a Hakea or something.
Currently, I use myoporum parvifolium as the seedling's host, then transplant out and use either olives, pistachio, or acacia as secondary hosts. Most native species are ok.
Do they strictly require desert type climates or will a Melbourne climate suffice if you give them good drainage and a sunny/warm spot?
They now grow in desert type situations, only because of over-collection and clearing of the better lands. Before this happened, they were extremely common, and will grow almost anywhere, including Melbourne. Drought and frost tolerent, they thrive given conditions nicer than a desert.
Good to see some action in here again
Obviously been a bit quiet !
