Important notes

in a bed: Peppermint spreads aggressively by underground runners. Keep it in a pot, otherwise it takes over the bed.

essential oil / large amounts: Menthol and pulegone in mint oil are toxic to cats (and dogs) — cats metabolise essential oils poorly. A stray leaf is usually harmless, but avoid concentrated mint oil/diffusers. ↗

Spider mites fine webbing, stippled leaves in dry air raise humidity, predatory mites, neem
Flea beetles many tiny shot-holes in the leaves row cover, keep soil moist, sticky traps
Mint rust orange pustules under leaves remove affected shoots, improve airflow, cut back to the ground in autumn
Powdery mildew white powdery coating on leaves improve airflow, water at the base, remove affected leaves
Verticillium wilt one-sided wilting and yellowing despite moist soil remove affected plants, rotate location, use resistant strains
