watering
Water Sisymbrium luteum when the top layer of soil starts to feel dry to the touch, usually once a week when temperatures are above 80°F. When temperatures are cooler, water can be given less frequently – approximately every 2 to 3 weeks. Make sure to water at the base of the plant, as this will help prevent fungal disease caused by moisture on the foliage. If the plant is placed in direct sunlight, it may need more frequent watering. Soil should be kept moist, but not soaked.
sunlight
Sisymbrium luteum, or common yellow rocket, does best in direct sunlight, receiving at least 8 hours a day. In spring and summer months, when the days are the longest, the plant should receive 8-10 hours of direct sunlight per day for optimal growth. During the shorter days of fall and winter, the plant should still receive at least 6-8 hours of direct sunlight for optimal growth and flowering. In addition, Sisymbrium luteum prefers a space with plenty of air circulation and the plant should be turned regularly to ensure even light reception.
pruning
For sisymbrium (Sisymbrium luteum), pruning should be minimal and should be done during the spring just before new growth begins. About 2-thirds of the existing stems should be removed in a staggered fashion (about a third each year). This can be done to increase air circulation, make room for more seed pods, reduce the risk of disease and keep the plant more compact. Once established, only weak or dead stems should be removed. Also, it may be necessary to remove seedlings while they are still small, as sisymbriums can become easily overcrowded.
