Aquatic Invasive Species & Water Gardens
This site will help you to properly protect and maintain your water garden to prevent the spread of Invasive Species.
Invasive species commonly appear in water gardens. They are organisms that come from another ecosystem either abroad or from within the country that are moved by artificial means – usually human mediated and are likely to cause economic or environmental harm or harm to human, plant or animal health.
A water garden is fundamentally an outdoor aquarium. The gardener needs to manage the pH, nutrients, and organisms introduced into the system. Just because a plant or animal is invasive doesn’t mean it can’t be ordered and delivered to your door or purchased locally. Unwelcome hitchhikers may also accompany your purchase. Plants and animals known to be invasive or prohibited in the state are often part of plant orders in the water or plant medium or even used for packing.
The following is a list of references and resources for additional information on identifying aquatic invasive species in your water garden, determining your hardiness zone, finding a local native plant nursery, and more.
This is a How-To Video that will guide you in the process of cleaning plants before adding them to a water feature. This is part of an Extension curriculum designed for the Penn State Master Gardening Program.
