Abstract
Trials of open-rooted plants of Pinus radiate in the winter rainfall region of South Africa and of P. taeda, P. elliottii and P. patula in the summer rainfall region are described. It is concluded that open-rooted plants can be used with confidence in both regions. Sites which are naturally difficult to establish in the winter rainfall region will require strict weed control. This is also likely to be necessary for the summer rainfall region. Soil sterilization and mycorrhizal inoculation in the nursery can significantly improve both nursery growth and field performance of the pines.
