Purchase trees from reputable nurseries with good quality control. Trees are generally available at 12 months and 18 months, costing approximately $5 and $10 on site respectively. Smaller trees cost less to transport but are more susceptible to setbacks once planted. Ask the nursery whether the mother stock has been verified as the true variety. Request information on the diseases experienced in the nursery. Orders can be placed year round, but generally orders are placed in January/February for delivery for spring planting in September. A deposit of 10% to 20% is generally paid on order, refunds of the deposit less an administration fee can generally be negotiated. Trees should not be transported in open vehicles as the wind can cause considerable damage. Consideration should be given to acclimatising trees that have been propagated in climates that are different from those in which they are to be grown.
