How do you eradicate primrose from your pond?

To eradicate primrose from your pond, start by manually removing the plants, ensuring to pull out the roots to prevent regrowth. Consider applying an aquatic herbicide specifically designed for use in ponds, following the manufacturer's instructions carefully to minimize harm to other aquatic life. Regular monitoring and removal of any new growth will help prevent reinfestation. Additionally, promoting a healthy ecosystem with competitive native plants can help suppress primrose growth over time.
