From Ground: If your annual bluegrass plant was originally grown in the ground, you should begin with thoroughly watering it to soften the soil. Dig a wide circle around the plant with the shovel or trowel, being sure the root ball stays undamaged. Afterward, gently work the shovel beneath the root ball, lifting the whole plant out of the ground with care.
From a Pot: If annual bluegrass was grown in a pot, the process could be easier. Start by watering it. Then, turn the pot sideways, holding the annual bluegrass near its base. Give a gentle tug, and the plant should slide out with the root ball intact. Be cautious not to pull from the top, as it may damage the plant.
From Seedling Tray: If annual bluegrass is in a seedling tray, it must be delicately handled to avoid damaging the roots. With one hand, hold the annual bluegrass plant's base, while using a small spoon or stick to carefully loosen the soil from the sides. Gently lift the plant once it's loose.
