Abstract
A process for planting aquatic plants and seeds underwater on the bottom and edges of an estuary, where an aquatic plant or seed which is ready for planting is positioned in a holder having a means for retaining the plant or seed. The holder further has a bottom gripping section which is secured to the holder. The preformed holders may be positioned on the bottom of the estuary or broadcast onto the surface thereof. The preferred bottom gripping sections are rocks, stones and mollusk shells. The holder also incorporates an organic button which retains the aquatic plant or seed during the planting process. The plant or seed retaining section can be designed to decompose in a predetermined period of time. This predetermined period of time may be correlated to the growing cycle of an aquatic plant or the germination cycle of an aquatic plant seed.
