Nursery Stock Awaiting Final Transplantation
Here bunches of seedlings such as those shown in the preceding illustration have been set out temporarily en masse to keep them in condition until time can be found for their individual transplantation. In cold weather and in dry soil the seedlings may thus be preserved almost indefinitely, retaining their vitality and being ready to take on growth when transplanted individually.
