3 Primary Causes of Seedling Stress
Moisture Loss (desiccation)
Exposure to temperature extremes
Physical injury
Transporting Stock3 Things to Consider:
Temperature:Keep the trees cool. Keep the trees coveredEnclosed trailer necessary; refrigerated trailer = optimalIf forecast hot, transport during cooler morning hrsIf stopping, park in shade
Space:Do not over-pack treesTightly packed trees can begin to heat up
Time: Shorter = better Unload into cooler ASAPDo not leave trees in truck overnight
Storage TipsTemperature: between 34 and 38F
Humidity: above 80% optimal
Air Circulation is good
Keep in nursery packages Package label: date monitor at 2 wks – mist roots
Molds white – don’t worry too much black – may be problematic
Minimize storage length. Longer storage results in mold and bud break
Planting Season in ND
Late April until early June
Get the trees in the ground – don’t wait
Soil temp above 50F is ideal plant too early – desiccation plant too late – too dry
