How to keep Marrubium Supinum.

Light

Stephan ex willdenow comes from sunny, tropical habitats and does best in direct sunlight. It prefers full sun but can tolerate partial sun, adapting well to lightly shaded spots.

Temperature

Stephan ex willdenow is native to habitats with temperatures ranging from 68 to 95°F (20 to 35℃). While it can adapt to seasonal changes, cooler temperatures may suppress its growth. Consider keeping this temperature range for optimal growth.

Fertilizer

One fertilizer application in spring is generally enough for Stephan ex willdenow, though multiple feedings can boost growth. Apply fertilizer every month to every month and a half. Fertilization improves the leaves' appearance and function, maintaining even color and a healthy texture. It also encourages root development and nutrient uptake for sustained plant health.

During this time, remove dead branches and deadhead flowers to encourage extended blooming. These practices enhance airflow, reduce the risk of disease, and promote vigorous growth, ensuring that Marrubium supinum is prepared for a robust summer season.
