From Ground: Begin by watering the wild mint at its original location to moisten the soil around it. Using a spade or shovel, carefully dig around the wild mint, ensuring a safe distance so as not to harm the root structure. Continue to work your spade underneath the root ball and gently lift it out of the ground. Try to maintain as much original soil around the root ball as you can.
From a Pot: Similarly, watering before removal will help protect the roots. Turn the pot sideways, grip the wild mint at the base and gently try to slide it out. If resisting, a tap on the bottom may be necessary.
From Seedling Tray: Water the wild mint before the removal. Using a small gardening tool, gently lift it out of the tray, ensuring that the roots and attached soil are as undisturbed as possible.
