Grasses for Masses - Frequently Asked Questions


Q:  Why are underwater grasses important?
A: Underwater grasses are beneficial in several ways:

  • They settle suspended particles from the water and stabilizing the sediments that are already on the bottom of the Bay.
  • They absorb excess nutrients (such as nitrogen and phosphorous) from the water.
  • They provide food and habitat for multitudes of aquatic creatures.
  • They slow wave action, which reduces shoreline erosion.
  • They produce oxygen.


Q: Why are underwater grasses in trouble?
A: Unfortunately, the Bay's grasses have declined significantly, mainly because of sediment and nitrogen pollution. When too much suspended sediment from runoff clouds the water, or when excess nitrogen causes algae blooms, Bay grasses cannot get enough sunlight to grow. The grass beds can die off and the Bay loses important habitat.

Q: What will I need to do as a participant in the program?
A: Here is an outline of program responsibilities:

  • Grow and maintain the plants for ten to twelve weeks in your home system.
  • Plant the seeds within a couple of days of receiving them.
  • Contact us if you have any problems or questions.
  • Join our "MyGrass" Google Group to get updates, trouble shoot, and meet other growers.
  • Return all the equipment at the end of the project.
  • Bring your plants and equipment to the Bay grass planting at one of the designated restoration sites.

Q: How much time will I need to dedicate to the program? 
A: Here is an outline of time you will need to allow for system set-up and maintenance.

  • 1-2 hours to attend a Grasses Workshop in February.
  • 24 hours to let water bubble to rid chlorine before planting seeds.
  • 60 minutes: assemble Bay grass growth chamber (attach and assemble lights, assemble filter, fill growth chamber with water, add heater, and plug in heater and filter).
  • 30 minutes: mix topsoil and sand, fill trays, cover with sand, lower into growth chamber, and plant grass shoots or seeds.
  • Daily: 5 minutes to check water, temperature, sponge, and algae level of growth chamber.
  • Half day in the Spring to attend a planting event with CBF.


Q:What kind of space do I need in my home?
A:You need to have a 4' X 4' space in a room with a stable temperature. We suggest a spot with natural light and stable temperature.

Q:Is there a program fee?
A: Yes, a fee of $40 covers equipment, training, plantings, and technical support. The fee allows us to buy new equipment and continue the program each year.

Q: How long will I be expected to grow the plants?
Volunteers grow the plants for approximately 10-12 weeks. Plantings will occur during the month of May.

Q: Can I plant the grasses on my local creek?
A: No! It is very important that we plant these grasses in the designated restoration sites that we have carefully chosen based on scientific data, water quality, and historical distribution of grass beds. We want to make sure that every restoration project has the highest possible chance of success, and that we learn from each planting to improve our restoration techniques. Your cooperation is essential.

Q:What should I do if there is a problem with the plants?
A: Call your local CBF Regional Coordinator as soon as you detect a problem with the plants. You can also post a comment on the Google Group to get feedback from CBF staff and other growers. 

Q: Do I have to attend the planting event?
A: Yes. We need all the participants to help out at the planting event. However, if for some reason you cannot make the planting, arrange for someone else to bring and plant your grasses at the event. CBF cannot pick up grasses from participants who are unable to attend the planting.

Q: What if I have plans to go away for a few days?
A: Not a problem--add extra water to the tub well above the power pump outflow. You may want to ask someone to check on the plants if you plan to be away for more than a weekend.
