Amendment materials modify soil structure and texture. Fertilizing A proper nutritional balance is important for proper growth. Over fertilization causes succulent, or weak, growth. Succulent growth dilutes the concentration of essential oils, thus limiting the flavor and aroma of the herbs. On the other hand, inadequate fertilization will limit growth, resulting in a stunted and weak plant.
Annual herbs benefit from a light application of a complete fertilizer after each harvest.
Mulching Mulch with pine bark, straw, or wood chips establish only herbs that tolerate moist conditions. Such mulches may rot plants that require drier conditions. You may use an inorganic mulch, such as pea gravel, around plants requiring a drier condition. Pruning Prune tender herbs to remove dead tissue in early spring, before growth begins. Prune herbs valued for their young foliage regularly during the growing season to encourage fresh, young growth.
