From Ground: Water the east Asian alder thoroughly before starting, to ease the soil and reduce stress on the plant. Use a shovel or spade to dig a generous circumference around the plant, taking care not to damage the root ball. Gently work your tool underneath and lift the east Asian alder out with as much root and soil intact as possible.
From Pot: Start by watering the east Asian alder to moisten the soil which makes it easier to remove. Tip the pot sideways and gently tap or squeeze the sides to loosen the root ball. Slowly pull the east Asian alder out while supporting the base of the stem and root ball.
From Seedling Tray: Water the seedlings to ensure the soil is moist. Use a spoon or a small transplanting trowel to scoop out the seedling with its surrounding soil, being careful to preserve the delicate root system.
