From Ground: First, water the yellow rocket plant generously to moisten the soil which simplifies the digging process. Using your spade, dig carefully avoiding the roots and create a trench around the plant deep enough to fully encase the root ball. Next, gently ease the plant from its original location while keeping the root ball intact. If the plant is large, wrap the root ball in burlap for protection during transit.
From Pot: Start by giving the plant a good watering. Turn the pot sideways, hold the yellow rocket plant gently by the base, and tap the bottom of the container until the plant slides out. Refrain from pulling the plant to avoid potential damage to the stem or roots.
From Seedling Tray: Water the yellow rocket seedlings first. Use a garden trowel or similar tool to carefully lift the seedling and its surrounding soil, making sure to retain as much soil around the roots as possible to reduce transplant shock.
