From Ground: First, sufficiently water the white water rose plant to moisten the soil around it. Then, carefully dig a wide ring around the plant using a shovel or spade, making sure that the root system remains intact. Gradually work the spade under the root ball, and gently lift the plant from the ground.
From Pot: It's quite straightforward to remove a plant from a pot. Turn the pot side down while supporting the plant base with your other hand. Gently tap the edges of the pot until the plant and the soil slide out. Avoid tugging on the plant stem to force it out.
From Seedling Tray: If the white water rose is in a seedling tray, water it first to hydrate the roots and make it easier for the soil to stick together. Then, gently push the seedling from beneath the tray and carefully lift it out, ensuring not to damage the delicate root system.
