any ideas how to propogate tea trees from seed, and whether they can also be
propogated from cuttings


One would propagate from cuttings to get the exact copy of the parent so if you wish to grow the colourful new varieties you would have to do cuttings. On the other hand they are easy from seed if you are wanting to grow type species, they are the ones you would find in the bush or the type that have not been manipulated.
