From Ground: First, water the yellow eyed sorrel plant to dampen the soil. This makes extraction easier and helps protect the roots. With a shovel or spade, dig a wide circle around the plant, making sure to go further than the expected spread of the roots. Carefully slide the tool beneath the root ball to lift the plant with as much of the root system intact as possible.
From Pot: Water the plant in the pot before starting. Turn the pot sideways and gently tap the sides to loosen the soil's grip on the pot. Gradually tilt the pot and guide the root ball out with care, using your hand to support the plant as it comes free.
From Seedling Tray: Water the seedlings to ensure the soil is moist. Carefully use a garden trowel or a fork to lift the individual seedling by pushing in underneath the roots, then gently lifting them out, taking care to keep soil around the roots.
