From Ground: Water the red mulberry to dampen the soil around it. This will make digging easier and helps to keep the root ball intact. Dig wide around the red mulberry, ensuring you avoid damaging the plant's roots. Once done, gently lift the plant out of the ground.
From Pot: Water the red mulberry till the soil is moist. Tip the pot sideways and tap it gently to loosen the plant. Support the plant by the base and pull it out gently.
From Seedling Tray: The red mulberry seedlings should be gently taken out from the tray when they have at least two sets of true leaves. Use a dibber or similar tool to loosen the soil around the seedlings then gently lift them out, holding by their leaves and not the stem.
