Keep the soil consistently moist, but not waterlogged, as Mentha requienii prefers damp conditions. Water thoroughly when the top centimeter of soil feels dry.

In hotter weather or if the plant is in full sun, it may require more frequent watering to maintain its preferred moisture level.

Regularly pinch back the stems to encourage a bushier, more compact growth habit and to prevent it from becoming leggy. This also promotes more foliage.

Deadhead spent flowers to maintain appearance and potentially encourage further blooming.

Easily propagated from stem cuttings. Take 4-6 inch cuttings from healthy plants, remove lower leaves, and place them in moist soil or water. Roots typically form within a few weeks, after which they can be transplanted.

Repot annually or biannually, preferably in spring, when the plant becomes root-bound or outgrows its current container. Choose a pot that is only slightly larger than the previous one, using well-draining potting mix.
