  1. Transplant dill outside

    Water the tray well an hour before you transplant. Roots slide out cleanly and settle in faster.

  2. Plant dill from seed, right in the garden

    Thin ruthlessly once seedlings are up. Crowded roots mean smaller crops from every plant.

  3. Direct-sow dill for cool weather

    Mid-season soil is hot. Sow a bit deeper than the packet suggests to find cooler, damper ground.

Dill Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
