Handling in the Field

Introduction

Many of the same principles for handling and storing tree seedlings at the district apply to handling and storing tree seedlings in the field. One important principle is to keep seedlings cool and their roots relatively moist when seedlings are removed from storage boxes for planting. Root hairs can be damaged in minutes if they are exposed to dry wind and low humidity. Temperatures higher than 36 degrees Fahrenheit will increase respiration and cause seedlings to deplete their food reserves. High temperatures also can allow gases to accumulate in tree boxes. These gases can damage seedlings severely and are a particular problem in pines that are coming out of dormancy. Seedlings damaged or killed in this manner are not easy to distinguish from healthy seedlings.

This section describes in detail how to prevent damage to the seedlings at the planting site:
