Long Island Mammoth Dill is particularly valued for its vigorous, tall growth, aromatic foliage, and large flower heads that produce plenty of flavorful seeds. Compared with compact dill varieties, it is especially useful for gardeners interested in collecting mature seeds for cucumber pickling, preserving, and seasoning.
Harvest dill seeds when the flower heads have dried and the seeds have changed from green to brown. Cut the mature seed heads carefully and place them upside down in a paper bag or suitable drying area to collect the seeds as they fall. Make sure the seeds are thoroughly dry before storing them or using them in homemade pickling recipes.
Yes, Long Island Mammoth Dill can be grown in large, sufficiently deep containers with good drainage. Choose a sunny location and use a loose, well-drained potting mix. Because dill develops a taproot and can grow quite tall, select a stable pot with enough depth for root development and protect the plant from strong winds.
