Days to Maturity: Approximately 40-60 days to leaf harvest; 70-90 days to seed harvest.
Sun Needs: Full sun with at least 6-8 hours of direct sunlight daily—essential for strong growth, flavor, and flower/seed production in Utah’s intense summer light.
Season Type: Warm-season annual herb; best started early—transplant after last frost or direct sow in spring.
Plant Habit & Support: Bushy plants grow 18-30 inches tall; generally self-supporting but may benefit from light staking in windy areas—space 12-18 inches apart.
Other Notes: Harvest leaves before flowering for best flavor; allow some plants to go to seed for pickling spice—monitor for aphids or dill-specific pests—organic mulch (like straw or compost) helps retain moisture and suppress weeds.
Best Planting Method: Transplant when nights stay above 55°F and soil is warm. Space plants 12-18 inches apart in rows or beds; plant at the same depth as in the pot. Amend soil with compost for fertility and excellent drainage—raised beds are ideal in heavier or alkaline Utah soils. Organic mulch (such as straw, compost, or grass clippings) around plants conserves moisture, suppresses weeds, and moderates soil temperature.
Watering Needs: Provide consistent, even moisture (about 1 inch per week)—drip irrigation is ideal in dry Utah air. Avoid letting the soil dry out completely, as this can cause bolting; mulch helps maintain steady moisture, and containers may need more frequent checks during hot spells.
Fertilization Needs: Incorporate compost or a balanced slow-release fertilizer at planting. Dill is a light feeder—avoid high nitrogen to prevent excessive foliage at the expense of flavor and seeds; organic options like compost tea provide gentle nutrients. Harvest leaves regularly by snipping stems to encourage bushier growth; collect seeds when heads turn brown and dry.
