From Ground: Water the st. Dabeoc's heath plant a few hours prior to softening the soil. Then use a digging fork or a spade to dig around the plant, leaving a generous diameter around the base to avoid damaging the root system. Once loosened, lift the plant gently from the base.
From Pot: First, water your st. Dabeoc's heath lightly to moisten the surrounding soil. Turn the pot sideways, hold it gently and tap the edge of the pot against any solid but non-damaging surface. This should loosen the root ball and allow you to slide it out. If this doesn't work, you may have to cut the pot away.
From Seedling Tray: Water the seedlings to keep the root ball intact during the transplant. Seedlings are delicate, so gently tease them out from their tray by holding onto their leaves or root ball, not the stem.
