From Ground: Water the grey willow to dampen the soil, making it easier to dig. Use a shovel or spade to carefully dig a wide perimeter around the grey willow, going deep enough to include the majority of the root ball. Gently lift the grey willow from the ground, preserving as much of the root ball as possible.
From Pot: Water the grey willow well before starting. Turn the pot sideways and tap the bottom or sides to loosen the root ball. Gently pull the grey willow from the pot, supporting the plant from its base.
From Seedling Tray: Water the seedling to ensure the soil is moist. Use a spoon or small tool to lift the individual seedling out of the tray, being cautious not to damage the tender roots.
