From Ground: Begin by watering the carpet phlox to make the soil around it moist, this will make digging around the root ball easier. Using a shovel or spade, dig a wide circle around the plant, ensuring to keep the root ball intact. Gradually work the spade under the root ball and gently lift the plant from the soil.
From Pot: Water the carpet phlox plant and allow it to drain to make removal easier. Gently tap the sides of the pot to loosen the soil. If the plant doesn’t slide out, carefully turn the pot upside down while holding your hand over the plant's base. Gently pull the pot away from the root ball.
From Seedling Tray: Water the seedlings well and allow them to drain. Using a garden trowel, carefully lift each carpet phlox plant from its cell, holding it by its leaves to avoid damaging the delicate roots.
