About this file
This is a technical specification document (#002) from the Illinois Division of Forest Resources that outlines proper care procedures for live-cold dormant tree seedlings. The document, dated January 2023, provides detailed instructions for handling and storing tree seedlings to ensure optimal survival rates and minimize initial mortality.
The specification describes two different treatment protocols based on temperature and timing conditions. For temperatures under 85°F when seedlings will be planted within 48 hours, the seedlings should remain in original unopened shipping containers and be stored in cool, shaded areas like the north side of unheated buildings or root cellars. For temperatures over 85°F or when storage exceeds 48 hours, seedlings must be kept in refrigerated storage at 33-38°F, never exceeding 40°F, and should be planted before leaf flush occurs. Both protocols emphasize gentle handling, avoiding tears in packaging, limiting bundle stacking to 2 high without support, and protecting seedlings from sun and air exposure.

ILLINOIS DIVISION OF FOREST RESOURCES
LIVE-COLD DORMANT TREE SEEDLING CARE; SPECIFICATION #002
Improper care of seedling stock is often the major cause in high initial mortality. Proper treatment of these new seedlings during the times temporary storage, and planting is necessary to insure initial survival rates.
TREATMENT DURING OPERATION
A. Under 85oF and seedlings planted within 48 hours after pick from Nursery.
• Leave seedlings in their original, unopened shipping container, until they can be planted
• Store packages in a cool, well drained, shaded area. Such areas include the north side of an unheated building (like a barn or woodshed), a root cellar, or an improvised lean-to.
• Handle bags gently, avoid tears, and avoid crushing. If possible, try not to stack the bundles greater than 2 bundles high without some form of support. When tears occur, they should immediately be repaired. Do not leave seedlings exposed to sun and or air.
B. Over 85oF or if trees must be held longer than 48 hours before planted:
• Place unopened seedling packages in refrigerated cold storage unit.
• Refrigerator unit should keep seedlings at a temperature of 33o to 38o Fahrenheit. This temperature should never be allowed to get above 40o Fahrenheit.
• Walk-in coolers make good holding areas for seedlings.
• If possible, try not to stack the bundles greater than 2 high without some form of support.
• Remove trees only as needed.
• Do not store longer than necessary. Seedlings should be planted before leaf flush occurs.
