Fernleaf
Fernleaf Dill is a compact dwarf cultivar of Anethum graveolens bred for gardeners who want fresh dill without the typical bolting rush. This open-pollinated variety lives up to its name with finely textured foliage that looks delicate and ornamental in the garden, reaching harvest readiness in just 55 to 60 days from sowing. Johnny's Selected Seeds describes it as their slowest-bolting dwarf dill, meaning you'll have a longer window to harvest leaves before the plant flowers and goes to seed. The tight, bushy growth habit and minimal spacing requirement (just 1 inch between plants) make it excellent for containers or small garden plots.

The slow-bolting nature of Fernleaf Dill sets it apart in the dill world, giving home gardeners weeks of fresh harvests instead of a brief window before the plant races to flower. Its dwarf, compact form takes up minimal space while still producing abundant feathery foliage, and the fact that thinning isn't necessary makes direct seeding remarkably forgiving. For anyone who's watched standard dill bolt in midsummer heat, this variety offers genuine relief without sacrificing the bright, classic dill flavor.
Fernleaf Dill is grown for its fresh foliage and seeds, both prized in the kitchen. The feathery leaves are harvested young for fresh use in salads, fish dishes, pickles, and Scandinavian preparations, while the seed heads are left to mature and dry for pickling spice blends or herbal infusions. The slow-bolting habit makes it particularly useful for gardeners seeking continuous fresh harvest rather than a single flush of material.
Sow 3 to 5 seeds per cell in containers or cell trays indoors. Germination occurs at temperatures between 60 to 75 degrees Fahrenheit. Transplant out when seedlings are ready, using 2 to 4 inch spacing in rows at least 4 inches apart.
Transplant indoor-started seedlings out once they are established and soil temperatures are between 60 to 75 degrees Fahrenheit. Space plants 2 to 4 inches apart in rows at least 4 inches apart. Handle seedlings gently to avoid damaging the delicate root system.
Direct seed in spring as soon as soil can be worked. Sow seeds 1/8 to 1/4 inch deep and 1/4 to 1/2 inch apart in rows at least 3 inches apart. Thinning is not necessary due to the compact growth habit. For continuous fresh harvests, make successive sowings every three weeks.
Begin harvesting foliage once plants are well-established, and continue right up until flowering begins. Pinch or cut leaves from the top of the plant to encourage branching and delay bolting. For seed harvest, allow seed heads to mature and watch for the seeds to begin turning golden brown, then cut the entire head and hang to dry. Regular harvesting of foliage actually extends the productive life of the plant by slowing its transition to flowering.
