Seedlings - 2 Year Old
Grown for two or three years in specialized seedling beds.
Transplants - 4 Year Old
Grown for two years in a seedling bed, then transplanted and grown for another year, allowing for a more robust root system.
Plugs are grown in containers with internal, vertical ribs and open bottoms, suspended in racks that hold the pots slightly above ground. The vertical ribs make the outer roots grow straight down. The open bottoms with no lip cause the roots at the base to air-prune themselves. People love planting plugs because they are quick and easy to handle.
