How do everbearing strawberries produce runners and how can they be managed effectively in a garden setting?

Everbearing strawberries produce runners, which are long stems that grow from the main plant and develop into new plants. To manage them effectively in a garden setting, you can either allow the runners to take root and grow into new plants, or you can trim them to control the spread of the strawberry patch. Regularly monitoring and pruning the runners can help maintain a healthy and productive strawberry garden.
