How to keep Lepidium Montanum.
Light
Mountain pepperplant is a sun-loving, perennial herbaceous plant that comes from open habitats and is commonly found in meadows and grasslands. It prefers full sun but can also tolerate partial sun conditions.
Temperature
Mountain pepperplant can tolerate a wide range of temperatures, but its distribution may still be restricted by specific combinations of moisture and heat. It does best in warm summer conditions with adequate rainfall or watering. Extended periods of cloudy, rainy weather or prolonged high temperatures can increase the chance of Mountain pepperplant dying. In winter, shielding it from cold can boost its survival rate.
Fertilizer
A single fertilization in spring is typically sufficient for Mountain pepperplant, though repeated feedings can maximize growth. Feed once a month to once every month and a half. Fertilizing improves leaf appearance and function, promoting consistent color and a healthy texture. It also encourages root growth and enhances nutrient absorption for long-term plant health.
Pruning
The mountain pepperplant thrives in rocky soils and has a low-growing habit. To encourage growth and flowering, prune the plant in early spring. Be careful not to over-prune, as this can cause stress. Regular pruning helps improve air circulation, reduce diseases, and maintain the plant's density. Additionally, remove spent flowers regularly to extend the blooming period.
