The closer the relationship between the stock and the scion, the greater will be the chance of success. In the latter case, selected forms of Macadamia tetraphylla and M.integrifolia are grafted onto seedlings of the same species. This enables robust plants to be produced which will fruit much more reliably than seedlings and at an earlier age. Basically, any Grevillea which is hardy and robust in a particular district would be worth a try as a stock plant for the difficult to grow grevilleas. Hakeas graft quite well onto the commonly grown species H. salicifolia and spectacular species such as H.francisiana and H.bucculenta are very reliable on this rootstock.
Mint bushes are often short lived on their own roots but are very reliable as grafted species.
Banksias, however, are more difficult to graft successfully although some success has be demonstrated by experienced propagators. This is probably the simplest and most convenient method for the beginner. The stock is cut off about 50 -100 mm above the soil level leaving a few leaves on the stock until the graft has been successfully established. A simple slit about 5-15 mm long is then made in the centre of the stem. A very sharp blade will be needed to ensure that the cuts are clean.
