From Ground: To remove the argentine senna plant, first ensure the soil around it is suitably damp by lightly watering it. Then, begin by digging a broad circle with your shovel or spade, ensuring you stay clear of the plant's root ball. Gradually work your shovel under the root ball, being careful not to damage the roots. Once you've sufficiently loosened the soil, gently lift the plant out of the ground.
From Pot: If you're transplanting a potted argentine senna, you'll need to carefully invert the pot while supporting the plant's root ball in your hands. Apply some gentle taps to the bottom to help loosen the compact soil and plant. Once loose enough, slowly slide out the plant.
From Seedling Tray: In case of seedlings, using a small trowel or your hand, you can gently scoop under the roots and lift the argentine senna seedling from its tray. Make sure you’re supporting the seedling by its root ball, and not by the stem.
