Dill seeds germinate best in warm soil temperatures, with the ideal range for germination falling between 60°F (15°C) and 70°F (21°C). However, the optimal temperature is typically around 70°F (21°C).

Direct sow in mild climates and for succession sowings later in the season. Otherwise start seeds indoors 4-6 weeks prior to your last frost date.

Dill should be transplanted outdoors after the last expected frost date once the weather has warmed, and the soil temperatures consistently reach at least 50°F (10°C) or warmer.

Full sunlight: at least 6-8 hours a day.

Seeds can be sown every 1-2″. Thin to about 12″ apart. Be sure to check the seed packet for specifics on your variety’s size.

Dill is a cool weather crop, with ideal daytime temperatures ranging between 60°F and 70°F (15°C to 21°C). While dill plants can tolerate cooler nighttime temperatures, they perform best when nighttime temperatures remain above 50°F (10°C). Dill is hardy to Zone 9, surviving down to 25°F (-4°C) for established plants, but protection from snow may be necessary.

Keep the soil consistently moist.  Water at the base of the plants to keep the foliage dry and reduce the risk of diseases.

Regular harvesting will encourage more growth. Remove flowers to refocus the plant’s energy into foliage and prevent bolting, which can turn dill leaves bitter and signals the end of the plants life.

Use a pair of scissors or garden shears to snip off the desired amount of stems from the outside of the plant, leaving the inside stems to continue growing and bushing out.

Dill is commonly propagated from seeds. When saving seeds from dill plants, it’s important to ensure that they have not been cross-pollinated. Different varieties of dill will cross-pollinate each other.

Dill is suitable for container growing and can be grown indoors during winter for continuous harvests. If planted outside during the warmer months of the year, dill readily bolts. Succession sowing every 2-4 weeks will ensure a continuous harvest.
