Abstract
A process for planting aquatic plants underwater on the bottom and edges of estuary's where an aquatic plant which is ready for transplanting is positioned in a holder having a means for retaining the transplantable plant. The holder may be weighted with a bottom gripping section to secure the holder including the plant to the estuary bottom. The preformed holders may be positioned on the bottom of the estuary or broadcast on the surface. The preferred gripping sections are rocks, stones and mollusk shells. The holder also incorporates an organic button which retains the aquatic plant during the planting process.
