Field-grown stock with exposed roots will dry and desiccate very rapidly — covering roots with a plastic sheet or tarpaulin is vital. On arrival home, water roots, cover from wind and store in a cool, shady area until planting. Planting should be done as soon as possible. If storing for an extendd period, heel roots into sawdust or loosely cultivated soil.
Container-grown, evergreen plants being transported uncovered at 80km on the back of a ute or trailer are subjected to the same leaf stress as if in a gale force wind. This is not recommended, particularly if travelling any distance.
Deciduous container grown trees, not in leaf during winter, do not require the same wind protection.
Trees and shrubs should be laid down with their tips facing the back end of the vehicle. If extending beyond the tailgate, they may need a flag tied at their tips. (For unwieldy branches, try lassoeing 'teepee' style with soft tie material, which we usually have on hand at the nursery.)
If transporting plants in your car, take care to make sure they do not overheat if the vehicle is parked in the direct sun. Water plants well and store them in a site protected from wind when you arrive home. Make sure they stay upright and water every couple of days in warm dry weather until they are to be planted.
Container plants dry out quite rapidly in hot weather. They don't want to be severely checked prior to transplanting.
