Care
Watering
Keep the soil moist but well-draining during the growing season. Regular watering two to three times a week is generally sufficient depending on climatic conditions. Reduce watering in fall-winter when the plant slows down.
Light exposure
Place this herbaceous plant in partial shade to bright light. It appreciates a location protected from strong winds and direct afternoon rays in very warm regions. A spot receiving 3 to 5 hours of direct light daily is ideal.
Soil
Prefer rich, well-structured soil that is slightly humus-rich, typical of Brassicaceae family terrain. Ensure satisfactory drainage to prevent root suffocation. Adding compost at the start of the season improves fertility.
Pruning and cutting
Regularly remove spent flowers to encourage continuous blooming. Eliminate yellowed or damaged leaves to maintain a neat appearance. Light pruning in spring rejuvenates the plant clump.
Fertilizer
Apply balanced fertilizer every two to three weeks during the active growing period. Moderate application is sufficient; excess would promote foliage at the expense of flowers. Stop feeding in fall-winter.
Diseases and pests
Watch for common pests affecting Brassicaceae such as aphids or whiteflies. Good air circulation reduces the risk of mold or fungal diseases. Intervene quickly if you notice any abnormal spotting or weakening of foliage.
Did you know?
The genus Nasturtium (true watercress) belongs to the Brassicaceae family, like cabbage and broccoli, and not to ornamental nasturtiums. This plant was long cultivated for its cooling and digestive properties in traditional herbal medicine. Its sterility makes it an interesting choice for gardens where you want to avoid unwanted self-seeding.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
