Research Summary on Pot-In-Pot Production and Planting Depth

Abstract

This focus of this research study investigates the nursery practice of placing trees deeply in containers to prevent wind-throw and excessive lean. After four months of observation, tree lean, caliper and root volume were analyzed, and results showed no association between planting depth and occurrence of windthrow. A lower proportion of trees required staking when planted at greater depth of soil. Species-specific associations between planting depth and root volume and caliper were observed, and these findings can help inform standard nursery practices.
