Does pennyroyal really repel insects?

Indeed, the pennyroyal plant is effective at repelling insects. It is among the most aromatic of the mint family, and the scent released by its leaves is particularly helpful in deterring mosquitoes and fleas.

How do I harvest and use pennyroyal leaves?

The plant is often utilized in natural pest repellents. Take advantage of the pruned stems from your pennyroyal in areas where unwanted insects are an issue. You can either place freshly cut stems around vulnerable spots or dry the stems and leaves to create pest-repelling potpourri blends.

How can I use pennyroyal in the landscape?

Pennyroyal is a classic cottage garden plant, though it may not be the most visually appealing choice. Primarily cultivated for its insect-repelling properties, if you choose to grow it, its spreading nature makes it ideal for filling empty spaces in your garden or large pots. Additionally, its abundant flowers will draw in butterflies and various pollinators.

Should I prune my pennyroyal plants?

Pruning your plants is essential for managing their growth effectively. Pennyroyal can spread endlessly through creeping stolons, much like other mint varieties, and may become invasive if not controlled. To maintain the plant within its designated area, pull up the edges where it is rooting and spreading, trimming as needed. It's advisable to do this more often during wet, warm weather—ideally on a weekly basis. Additionally, trimming pennyroyal plants after flowering helps to keep them looking tidy.
