Two studies were conducted to evaluate different irrigation regimes for production of container-grown sawtooth oak. Three irrigation treatments (single, 3 times daily, and 6 times daily) and 2 substrate treatments (100% pinebark and 4:1 (v:v) pinebarkxoir) were evaluated to determine their effects on irrigation application efficiency and growth of sawtooth oak (Quercus acutissima Carruthers) in a pot-in-pot production system. Irrigation application efficiency increased with cyclic treatments compared to a single application and was increased with the pinebark: coir substrate compared to pinebark alone in the single application treatment. Growth was greater when irrigation was applied in 6 cycles than in 1 single application. Trees grown in pinebark: coir substrate were larger than those grown in the pinebark substrate.
