watering

Water dame's rocket weekly to keep its soil evenly moist, preferably in the morning. Early in the season, the plant may require daily watering to get it established. Once established, it can survive with weekly irrigation. Avoid over-watering as it can cause the roots to rot and the plant to die.

sunlight

Dame's rocket (Hesperis matronalis) requires at least 6 hours of direct or indirect sunlight daily, preferably in the morning or early afternoon. This species grows best in full sun but tolerates partial shade. During the summer months, it should receive full sun, as this will promote better flowering. When growing in the winter, direct sunlight might be decreased to 2-4 hours a day as the species may be more dormant during this period. It is important to remember that too much direct sunlight during extremely hot days may burn the leaves of the plant.

pruning

Dame's Rocket (Hesperis matronalis) should be pruned yearly in late winter. During this time, prune away any dead or damaged growth and remove any flower stalks after they have bloomed. If necessary, prune away any of the older branches down to the newer growth to encourage new stems and growth. If the shrub is overgrown, prune it back to half its size to promote bushier growth.
