From Ground: First, water the hedge hyssop plant to dampen the soil. Then, dig a wide trench around the plant using a shovel or spade, ensuring a generous amount of soil around the root ball to keep it intact. Carefully work the spade under the root ball to lift the plant out with minimal root disturbance.
From Pot: Water the hedge hyssop plant before starting. Gently tip the pot on its side and tap the bottom to loosen the root ball. Slide the plant out while supporting the stem, being careful not to tug on the plant, which could damage the roots.
From Seedling Tray: Prepare by watering the soil to make it moist. Use a hand trowel or fingers to gently ease the hedge hyssop seedling out of the cell, ensuring to bring along the surrounding soil to preserve the delicate root system.
