Dill Weed Care

Dill weed (Peucedanum graveolens) is an herbaceous annual that grows to a height of about 2 feet, with a spread of about 8 inches. The plant is characterized by lacy, delicate green foliage, bright yellow flowerheads and small seeds that are commonly utilized for medicinal and culinary uses. Dill weed has been cultivated for upwards of 5,000 years.
  1. Culture

    • Dill weed is particularly adept at surviving in subtropical and tropical climates, though the plant is hardy to temperatures as low as USDA zone 8. Dill requires full sunlight and a moderately rich, well draining soil. For best results, plant in a soil with a pH between 5.3 and 7.8, and protect the plant from wind. Water regularly, but do not allow the soil to become water logged or flooded.

    Maintenance

    • Dill weed is mostly pest and disease free, although aphids may become a problem, particularly for young plants. Wash plant with a direct stream of water, and remove heavily infested leaves, if aphids are present. Rot rot may occur in poorly draining soils, or in overly wet soils. Trim the tops of the plant's flowers regularly to prolong the plant's life cycle and keep it from going to seed. Do not water from overhead if possible, as this increases the risk of rot and fungus.

    Propagation

    • Sow dill weed seeds anytime between April and June, covering seeds with a very fine layer of soil to help aid germination. If the soil is sufficiently warm, seeds should germinate in just two weeks. Sow regularly from May until June to keep fresh dill in constant supply. Seeds may be planted in fall if a mild, temperate winter is expected. Do not transplant dill, as disturbing the roots usually causes the plant to bolt.

    Harvest

    • Dill weed is best harvested in the early morning, when the plant is moist and full of flavor. Harvest when the plant is mature, but before the flower buds have opened. Fresh dill may be placed in a cup of cool water and kept in the fridge for two to three days. Dill weed may also be dried on wax paper in a dark place, and then sealed in an airtight container.
