How to Grow Dill
- Start with seeds, as dill dislikes transplanting due to its long taproot.
- Plan for succession sowing every 2â3 weeks through midsummer for continuous harvests.
- Choose a sunny location with well-drained soil and protection from strong winds.
When to Plant Dill
- Dill is a cool-weather lover: sow seeds outdoors after the last estimated spring frost.
- In very warm climates, try sowing several weeks before the last frost for early growth.
- Continue sowing at intervals until midsummer for an unbroken dill supply.
Where to Plant Dill
- Pick a spot that receives full sun (at least 6â8 hours daily).
- Select an area with well-draining soil, but keep soil evenly moist during germination.
- Tall dill varieties benefit from wind protection or staking.
- Can be grown in the ground, raised beds, or a deep container (minimum 12 inches deep to accommodate the taproot).
How to Plant Dill
- Prepare the Soil: Loosen soil in your planting area to at least 12 inches depth. Add compost or well-aged manure if desired.
- Direct Sow Seeds: Plant seeds â to ¼ inch deep (about 3â6mm) and gently cover. Space seeds about 4â6 inches apart for leaf production or up to 10â12 inches for large varieties.
- Row Spacing: For garden beds, keep rows approximately 2 feet apart.
- Water: Maintain consistent soil moisture until seeds germinate (about 10â21 days).
Tip: If you want ongoing fresh leaves, practice succession sowing: every 2â3 weeks, plant new dill seeds until midsummer.
Ideal Growing Conditions for Dill
Soil
- Type: Dill thrives in loamy, well-drained soil, rich in organic material.
- pH: Slightly acidic to neutral (6.0 to 7.5).
- Moisture: Keep the soil moderately moistâavoid soggy conditions.
What others are reading
Sunlight
- Plant in an area receiving full sun. Dill will tolerate partial shade, but growth may be less vigorous.
Watering
- Consistency is key: Keep the soil evenly moist in the seedling stage, but let the soil dry out slightly between waterings once established.
- Avoid overwatering: Dill does not tolerate waterlogged soils.
Temperature
- Dill germinates best at soil temperatures of 60°F (16°C) or higher.
- It prefers cool to warm weather and will bolt (go to seed) more quickly in summer heat.
Fertilizing
- Dill needs little additional fertilizer if planted in rich, organic soil.
- For poor soils, side-dress with compost or a balanced organic fertilizer at midseason.
Dill Care and Maintenance
Thinning Seedlings
- Thin plants when seedlings are 3 inches tall.
- Use scissors to snip extras at soil level, spacing remaining plants 6 to 12 inches apart depending on the variety.
Supporting Tall Plants
- Large cultivars like âMammothâ may need staking, especially in windy locations.
- Mulch around the base of plants to retain moisture and reduce weeds.
Container Growing
- Dill grows well in containers if they are at least 12 inches deep to support its long taproot.
- Ensure containers drain well and position in full sun.

How to Harvest Dill
When to Harvest
- Leaves (Dill Weed): Start harvesting as soon as plants have four to five leaves. The flavor is best just before flowering.
- Seeds: Harvest after flower heads turn brown and seeds are fully formed but before they drop.
How to Harvest
- For leaves: Use clean scissors or pruners to snip the necessary amount of foliage. Harvest early in the day after dew dries for best flavor.
- For seeds: Cut the entire flower head and invert into a bag or container to let seeds dry and fall off naturally.
- For continuous fresh leaves: Snip only what you need. For larger harvests or end-of-season cutting, trim plants back to a few inches above the soil; new growth may emerge.
Storing and Preserving Dill
- Fresh Storage: Wrap stems in a damp towel and refrigerate in a plastic bag for up to a week.
- Drying: Hang stems upside down in a warm, well-ventilated space until crumbly. Store dried leaves in a sealed container, out of direct sunlight.
- Freezing: Chop fresh dill and freeze in ice cube trays with water or oil for convenient portions.
- Seeds: Store thoroughly dried seeds in an airtight jar in a cool, dark location; they keep for a year or more.
Troubleshooting Dill Problems
- Bolting: Dill may bolt (flower and set seed early) in hot weather. For a steady supply, succession sow every 2â3 weeks and harvest young foliage often.
- Leggy Seedlings: Insufficient sunlight causes plants to stretch. Move to a sunnier spot or thin seedlings.
- Yellow Leaves: Can indicate overwatering, poor drainage, or nutrient deficiency. Adjust care as needed.
- Pests: Watch for aphids and caterpillars. Encourage beneficial insects or spray soapy water to control pests.
- Disease: Fungal issues (e.g., powdery mildew) may develop in damp or overcrowded areas. Grow with good air circulation and avoid overhead watering.
Top Tips for Abundant Dill
- Direct sow seeds where you want plants to growâdill dislikes transplanting.
- Thin seedlings for adequate space depending on variety (6â12 inches apart).
- Mulch around base to preserve soil moisture and keep weeds at bay.
- For prolonged harvest, succession sew and avoid letting all plants flower at once.
- Companion plant with crops that benefit from pollinators.
Popular Dill Varieties
- Mammoth Dill: Grows up to 5 feet tallâgreat for seed production and tall screens.
- Bouquet Dill: Compact, slower to bolt, and good for leaf harvests.
- Dukat Dill: Flavorful and especially leafyâideal for salads and fresh dishes.
Frequently Asked Questions (FAQs)
Q: Can I grow dill indoors?
A: Dill can be grown indoors in a container with at least 12 inches of depth and placed in a sunny window or under grow lights. Growth will be spindlier compared to outdoor dill due to lower light intensity.
Q: How can I prevent dill from bolting?
A: To delay bolting, sow new seeds every two to three weeks and harvest early. Planting in partial shade during hot months can also slow down flowering.
Q: Does dill regrow after cutting?
A: Dill will regrow if harvested by cutting above the main growth point. However, once it bolts and sets seed, new leaf growth slows dramatically or stops.
Q: What should I avoid planting near dill?
A: Avoid planting dill near carrots, tomatoes, and fennel as these may compete or cross-pollinate, impacting quality and yield.
Q: Is dill a perennial?
A: Dill is an annual in most regions, completing its life cycle in one season. However, if seeds drop, it readily self-sows for next year’s crop.
Summary: Growing Dill for Every Garden
With its value as a culinary herb, pollinator magnet, and easygoing nature, dill is a must-have for the home garden.
