Be Plant Wise Trail
The Be Plant Wise campaign is supported by the National Botanic Gardens, and was launched on
Thursday the 8th March, 2012 by Jimmy Deenihan TD, Minister for Arts, Heritage and the Gaeltacht.
The campaign highlights the actions gardeners can take to prevent aquatic plants in their
ponds from getting into the wild.
There are also many other common garden plants which we should guard against escaping into the wild.
We have highlighted 16 of these in the National Botanic Gardens as part of a trail to draw
attention to the problems they cause.

All responsible gardeners should:
- Compost with care – make sure you dispose of discarded plants properly; pond and fish tank water should be discarded away
from streams, rivers, ponds or lakes;
- Stop the spread – be careful not to introduce invasive species into the wild, even accidentally,
as you could be breaking the law; and
- Know what you grow – pick the right plants for your pond and manage them carefully. Choose non-invasive species where possible.
