From Ground: Water the bitter panicgrass plant to dampen the soil, it makes the removal easier and less stressful for the plant. Dig a wide trench around the plant with the shovel or spade. Make sure the plant's root ball stays intact. Carefully work the spade under the root ball to lift the plant.
From Pot: Water the bitter panicgrass plant well before taking it out of the pot. Tip the pot sideways and gently tap the edges. If the plant doesn’t easily slide out, you may need to tap slightly harder but be careful not to harm the plant.
From Seedling Tray: Moisten the soil first before carefully removing the bitter panicgrass seedlings by pushing them out from the bottom. Handle the seedlings by their leaves to avoid damaging the tender stems.
