Production and early field performance of RPM® seedlings in Missouri floodplains

Abstract

A new nursery culture process has been developed to produce large container RPM? seedlings in an effort to improve the success in artificially regenerating hardwoods. Major features of the process include air root pruning of seedlings grown in a well aerated soil medium to encourage a dense, fibrous root system. Production has focused on native bottomland tree, shrub, and herbaceous species. Field plantings of RPM? seedlings have been done in agricultural floodplains throughout Missouri. In one such planting, the survival and growth of pin oak and swamp white oak RPM? and bareroot seedlings are evaluated when seedlings are established with soil mounding and a redtop grass cover crop.
