Fall Water Garden Tips

Enjoy water gardening? Caring for water gardens in the fall helps to reduce future problems in both your ponds, water gardens, and wild waters!

Reducing Invasive Pet and Plant Escapes (RIPPLE) is crucial to keep in mind when removing unwanted plants and fish. Some of the most popular water garden plants sold, including water lettuce, water hyacinth and European water clover, are not native to Michigan and should never be released into waterways, lakes and streams. Outside of cultivation, these plants can create thick mats that reduce oxygen levels, block sunlight, and prevent growth of submerged vegetation. Mats interfere with recreation and can have a negative effect on fish and other aquatic species in an infested area. Unwanted plants should be placed in a sealed bag in the trash.

Fish and other live beings from water gardens should also never be released into water bodies. If you find your water garden with an overabundance of fish in the fall contact a local retailer, find another water gardener that has space for additional fish, or trade with another hobbyist.

If you suspect a non-native plant or animal in the wild, please report the occurrence to the Midwest Invasive Species Information Network (MISIN) or contact the Lake St. Clair CISMA directly at CISMA@macombgov.org. For more tips, visit this MSU Extension Water Garden Care page.
