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
