Got one seed germinating with the +40 C weather from the 5 planted the other day.
I removed the wings from around the seeds, nicked the coat at the edge (the resulted in one seed snapping in half!!!! careful) and soaked overnight in warm smoke water. They had swelled marginally the next morning.
Potted them up in 3:1 native mix:perlite. With the small addition of some granite dust.
Hope she likes it.
I'm planning to eventually keep it growing in a large pot with well draining soil, on the dry side in the winter. When large enough I'll try and graft some branches onto G. robusta seedlings.
