Divide the Sea Pink in the early spring when emerging from dormancy. First water well the day before to hydrate the plant well. Pull from the earth, being careful to dig far enough out not to damage its existing roots. To divide, cut through the roots with a sharp knife or pruners. Replant in a rich, well-draining garden mix. Place the roots at the same level as the previous plant adding soil and root hormone to the base of the hole. Water the roots and fill the hole with existing soil and amendments. Mulch around the plant to hold in the moisture. Check the moisture each day, add water until the roots establish, then back off on watering once established and water when the soil dries out.
