Build an Oyster Garden With Your Child—and Help Clean Charlotte Harbor

A hands-on family science project that restores local waterways

By Natalia Thompson September 8, 2026

Looking for a fun, hands-on activity that makes a real difference in our community? Families in Port Charlotte, Punta Gorda, Englewood and surrounding areas can help restore local waterways by creating a Vertical Oyster Garden, also known as a VOG.

It's part science experiment, part wildlife habitat and part environmental service project—and it begins with recycled oyster shells!

What Is a Vertical Oyster Garden?

A Vertical Oyster Garden is a tower made from cleaned, recycled oyster shells. The shells are threaded onto strong marine rope or stainless-steel wire and suspended from a dock in tidal salt or brackish water.

The recycled shells provide a hard surface where baby oysters, called oyster spat, can attach and grow. Over time, the hanging shells can become a small living reef filled with oysters and other marine creatures.

This is not a garden for growing oysters to eat. Its purpose is to improve water quality and create habitat for local wildlife.

How Do Oysters Help Clean the Water?

Oysters are nature's tiny water-filtration superheroes. As they filter the water, they help remove algae, excess nutrients, organic matter and suspended particles.

Oyster gardens also provide food and shelter for small fish, shrimp, crabs and many other animals. Healthier oyster populations can support clearer water, healthier seagrass and a more productive estuary.

According to the Charlotte Harbor Environmental Center, Charlotte Harbor has lost more than 90% of its oyster population because of development, dredging, nutrient pollution and stormwater runoff. Creating new places where young oysters can attach and grow is one way local families can help.

What You Will Need

  • 12 used oyster shells that have been properly cleaned and prepared
  • Strong marine rope or stainless-steel wire
  • A drill and appropriate drill bit
  • Protective gloves and safety glasses
  • Pliers, if using wire
  • A stainless-steel eye bolt for attaching the garden to a dock
  • Access to an eligible dock on tidal salt or brackish water

For safety and environmental reasons, families should obtain prepared shells from a participating conservation organization or workshop instead of collecting and immediately using restaurant shells.

How to Build Your Oyster Garden

  1. Begin with 12 cleaned and properly prepared oyster shells.
  2. An adult should carefully drill a hole through the center of each shell while wearing protective gloves and safety glasses.
  3. Let your child thread the shells onto strong marine rope or stainless-steel wire. Children should wear gloves because oyster shells can have sharp edges.
  4. Arrange the shells face-to-face in six pairs. As the shells are added, they will create a vertical tower on the rope.
  5. Secure the bottom and top of the tower so the shells cannot slide off.
  6. Attach the upper end of the rope to a stainless-steel eye bolt installed on the side of the dock. An adult must complete the installation.
  7. Lower the oyster garden into tidal salt or brackish water. During high tide, the garden should be completely underwater. During low tide, some or all of the shells may be exposed.
  8. Make sure the tower does not rest on the bottom or touch nearby oysters, boats or other objects.
  9. Be patient! It may take several months for baby oysters to attach to the recycled shells and begin transforming the family project into a living miniature reef.

Turn It Into a Family Science Project

Building and observing an oyster garden can teach children about:

  • Oyster life cycles
  • Water filtration
  • Estuaries and tides
  • Recycling and conservation
  • Fish and wildlife habitats
  • The importance of protecting Charlotte Harbor

After installation, children can check the garden regularly with an adult, take pictures and keep a nature journal. Record the date it was installed and look for changes over the following months. Your child may eventually notice new oysters and small marine creatures living among the shells.

Does Your Family Need a Dock?

The oyster garden must hang from a dock located on tidal salt or brackish water. Freshwater canals are not suitable because oysters cannot survive there.

If your family does not have an eligible dock, you can still participate. Families may be able to attend a community workshop, help prepare oyster gardens or make one for installation at a participating public or community dock.

Always obtain permission from the dock owner before installing an oyster garden. Do not collect live oysters or install a homemade structure without consulting a local conservation organization.

How to Participate Near Port Charlotte

Charlotte Harbor Environmental Center offers hands-on Vertical Oyster Gardening programs for community members, schools, HOAs, boating clubs and other local groups.

Participants learn about the water-quality challenges facing Charlotte Harbor and help construct oyster gardens using recycled shells collected from local restaurants.

Public workshops are free, although registration and space limitations may apply. If no upcoming workshop is currently listed, families and community groups can ask about arranging a private workshop.

Families closer to Englewood can also contact Lemon Bay Conservancy. Its “One Dock at a Time” program provides free Vertical Oyster Gardens to qualifying owners of docks on tidal waterways. Volunteers may also be available to assist with pickup or installation.

Small Shells Can Make a Big Difference

A family oyster garden may look small, but it can become a miniature reef, a home for marine animals and a natural filtration system working every day.

For children, it offers a powerful lesson: protecting our environment doesn't always require a huge project. Sometimes change begins with 12 recycled shells, a little patience and one family willing to help—one dock at a time.

Safety note: Adults must handle the drill, wire, tools and dock installation. Children may help thread and arrange prepared shells while wearing protective gloves. Vertical Oyster Gardens are intended for habitat restoration and water-quality improvement, not for harvesting or eating oysters.
