From Ground: First, you'll need to water the missouri foxtail cactus a day before the transplanting process to reduce shock. Then, using your shovel, dig a wide trench about a foot away from the plant's base, leaving the root ball intact to avoid damage. Gradually work the spade under the root ball, and slowly lift the plant from its spot. If the plant is large, use a wheelbarrow to move it to the new location.
From Pot: Water the missouri foxtail cactus plant well before starting. Turn the pot sideways carefully, hold the plant at its base, and try to ease it out. If the plant is stuck, squeeze the sides of the pot to loosen the soil and try again.
From Seedling Tray: Water the tray to dampen the soil, making it easier for the seedlings to slide out. Using a gardening fork, carefully lift the tiny seedling from the bottom to ensure the roots don't get damaged.
