From Ground: For removing a grown field rose plant from the ground, first water the soil around the plant to make it damp. This ensures less stress to the plant during uprooting. Use your shovel or spade to dig a wide trench around the plant. Make sure not to cut or damage the root ball when digging. Gradually work the spade under the root ball to lift the plant from its original location.
From Pot: If field rose is growing in a pot, water it well before removing. Invert the pot and lightly tap on its sides. The plant should slide out along with the root ball. Handle the plant by its base not by its stems to avoid breaking.
From Seedling Tray: If you're transplanting field rose seedlings, water the tray first. Then gently lift the seedlings by their leaves, not by the stem, to avoid damage.
