Even natural habitats require some degree of maintenance. These are a few things you can do to ensure that your marsh remains healthy and productive.

  • Each spring remove wrack (debris and dead vegetation) that accumlates over the winter. This debris will smother new plant growth.
  • Learn to identify the plants growing in your marsh - both native and non-native - and eliminate undesirable species before they spread and degrade your marsh. Common Reed (Phragmites) is one species to watch out for.
  • If your marsh is damaged by feeding geese or severe storms, you may need to replant areas with new marsh grasses.
  • Be aware that lawn chemicals (pesticides and fertilizers) can harm your marsh.


  • Marsh plantings do not require fertilizer.
  • We do not recommend mowing your marsh.

Marsh Hibiscus
Marsh Hibiscus (Hibiscus moscheutos) is one desirable native species that may appear in your marsh.
