From Ground: Initiate by
watering the perez's sea lavender plant to dampen the soil, a day before the transplanting day. Then, with the help of a shovel or trowel, dig a wide circle (approx. 12 inches diameter) around the plant; this ensures you don't damage the root system. Once that is done, you can gently lift the plant up, taking utmost care to preserve the roots as much as possible.
From Pot: Water the potted perez's sea lavender plant well before starting the process. Turn the pot sideways, hold the plant by its base, and gently tug it out. In case the plant doesn't come out easily, you can run a knife around the inside of the pot to loosen the roots.
From Seedling Tray: Once the seedlings have grown two to three sets of leaves, they are ready to be transplanted. Gently hold the seedlings by the leaves (not by stem) and with a spoon, scoop them out, being careful not to damage the root system.
