From Ground: Start by watering the soil around leather-bulb tulip to make the removal process easier. Then, use a shovel to dig a circle around the plant that's wider than the width of the plant's leaf spread. Make sure not to cut into the root ball. Lift the plant carefully whilst keeping most of the soil attached to its roots.
From Pot: Water the plant well before removal. Turn the pot sideways, while holding your hand over the plant's base. Carefully pull the pot away from leather-bulb tulip, ensuring you do not damage the plant's root system in the process.
From Seedling Tray: Water leather-bulb tulip thoroughly, then gently hold the base of the plant and lift it, making sure you pull up as much of the root system as possible. Avoid yanking as this could damage the delicate roots.
