European Searocket

European Searocket should be watered deeply once a week, allowing the soil to dry out slightly between waterings. The plant should be watered until water runs out of the drainage holes at the bottom of the pot. During periods of drought, it can be watered more frequently, but be sure to keep the soil just lightly moist at all times – never soggy. The soil should never be completely dry for more than a day or 2. This plant needs more water in hotter temperatures, so avoid underwatering, and water more often during hot summer months. Overwatering can cause root rot and can kill the plant, so make sure there is good drainage in the pot. European Searocket is tolerant of salty conditions, so it can be watered with water from a saltwater aquarium if needed.

European Searocket requires full sun for optimal growth and flowering. In most of its native range, this plant should receive at least 4 to 6 hours of direct sunlight a day. In high-altitude regions, or during summer months, it may even require up to 8 hours of sunlight a day in order to thrive. Allowing the plants to remain in partial shade is usually not suggested for this species.

European sea rocket should be pruned in the late winter or early spring before new growth begins. This is usually done when the plant is still dormant. A light pruning of dead branches or “suckers”, should be done to encourage optimal plant growth. Pruning can also help to keep the plant in a more aesthetically pleasing shape. Pruning should not be done aggressively, as it can damage the plant and stunt its growth.
