From Pot: First, water the silvery broom in the pot thoroughly to moisten the root ball. Gently tap the sides of the pot to loosen the soil and grip the base of the plant. Carefully tilt the pot and slide the silvery broom out, supporting the root ball with your hand.
From Seedling Tray: Water the silvery broom seedlings lightly to make the soil pliable. Using a spoon or a dibber, ease the seedlings out of the tray with care, making sure to keep as much of the root system intact as possible.
From Ground: Water the area around the silvery broom to ease the soil and reduce root damage. Use a shovel or spade to dig a generous circumference around the plant, going deep enough to include the full extent of the root ball. Pry the plant out of the ground gently with the spade, keeping the roots and soil together as much as possible.
