From Ground: Moisten down the soil around the willow oak to ensure easier extraction. Dig a trench wide enough to fit a spade or shovel around the willow oak. Gently work the spade underneath the root ball, slowly prying the plant and its roots free while keeping as much of the root ball intact as possible.
From Pot: Start by
watering the willow oak generously, then invert the pot gently while holding onto the base of the willow oak. If the willow oak resists, you may need to tap the edge of the pot lightly to dislodge it. Never pull it out forcefully as it might damage the root.
From Seedling Tray: Lightly water the seedlings. Use a dibber or your fingertip to push up from the hole’s base, allowing the seedling to pop out, intact with its roots and soil.
