Planting Tips:
Direct sow Mammoth Long Island Dill seeds outdoors in spring after the danger of hard frost has passed. Dill develops a long taproot and generally performs best when sown directly where it will grow rather than transplanted.

Plant in well-drained soil with plenty of sunlight and keep the soil evenly moist while seeds germinate and young plants become established.

Harvest fresh dill leaves as needed throughout the growing season. For homemade pickles, allow plants to mature and develop their characteristic flower and seed heads.

For a continued supply of fresh dill leaves, sow additional seeds every few weeks during suitable growing weather. Allow some plants to flower if you want to attract bees and other beneficial insects or harvest mature dill seeds.
