Garden Yellowrocket

Garden Yellowrocket should be watered as needed, but only when the top few inches of soil are dry. Generally, Garden Yellowrocket need about 1 inch of water per week in late spring and early summer when they are actively growing and flowering. During periods of extended dry weather, it is best to water about every 2-3 days, or when the soil is just slightly dry. Water Garden Yellowrocket heavily about once per month to flush out salts left in the soil from fertilizers and help maintain optimal soil condition.

Garden Yellowrocket (Barbarea vulgaris) is full-sun to part-sun loving plant that does best in 6 to 8 hours of sun per day. The sun needs to be direct and intense. In areas that experience intense heat for the majority of the summer, the plant will need some shade during the hottest part of the day. Garden Yellowrocket can handle full sun from late spring to early summer, as long as it is not exposed for more than 6 hours per day. The plant will benefit from some shade during the afternoon when temperatures reach their peak.

Garden yellowrocket should be pruned in late winter or early spring before the plant begins to send up new growth. Pruning should be moderate; only a few inches of the existing stems should be cut back, leaving 2 to 3 nodes or growing points above the soil. This spurs new growth which leads to additional buds and flowers later in the season. Pruning any more than a few inches could stress the plant and reduce the number of flowers it develops.
