How to Grow Dill

Dill is an herb that serves multiple purposes in the garden. It’s an attractive plant in either the herb or flower garden. It grows fine, feathery-like foliage that’s used as a delicious flavoring. It also produces large, ornamental umbrella-like flower heads that produce dill seeds. When conditions are right, the seeds will spread and sprout to grow the next season.

All about dill

In addition to its many uses in the kitchen, dill plants attract butterflies and other pollinators to the garden. Dill is a host plant to adult female butterflies, like black and anise swallowtails. Butterflies lay eggs on the dill to feed their caterpillars. Plant plenty of dill to ensure enough for gardeners and butterflies alike.

Dill is an adaptable and fast-growing tender annual plant that can reach 3 or more feet tall with an airy, upright habit. Dill (Anethum graveloens) can be planted in spring for a summer crop. Unlike many other herbs, dill can tolerate slightly dry soil conditions.

Known for its culinary, cut flower and medicinal uses, all parts of the dill plant are aromatic, from its leaves to seeds and flowers. The flowers are fragrant as cut flowers and can also be dried.

Dill is easy to grow from seed and can be started indoors or directly sown in the garden. Start seeds indoors early in spring and allow about two weeks for seeds to germinate. Wait for plants to be several inches tall before hardening off and planting.

To direct sow, plant seeds about ¼ inches deep and 1-2 inches apart. If planting several rows, leave 6-8 inches between rows.

Dill transplants are also available at garden centers. Before planting, give the plants time to become acclimated to outside conditions. Keep the soil moist until the plants become established.

Dill needs room to grow, at least 12 inches between plants. Be sure to thin crowded plants so foliage will be thick and lush.

If you want to ensure fresh dill leaves through the season, continue to sow seeds every 3-4 weeks from spring into fall using a succession planting method. Plants will decline after flowering, another reason to keep up with successive plantings.

Types of Dill

There are several popular varieties of dill. Look for the kind that best matches your favorite uses.

Hera is a dill variety known for its masses of blue-green leaves and a long season of growth before it starts to flower and goes to seed.

Fernleaf is a dwarf dill that does well in small spaces and containers; it grows to less than 2 feet tall and stays compact.

Long Island Mammoth is an especially vigorous variety of dill that matures quickly to about 36 inches in height. Its large flowers produce a large number of dill seeds.

Dukat is another dill variety that is slow to go to seed. The foliage forms and stays on the plants before the plants form exceptionally large seed heads.

Requirements for growing dill

Light requirements

Locate a sunny spot in the herb, vegetable, or ornamental garden. Dill prefers full sun to grow to its full potential, but it can also grow under partial sun conditions. One of dill’s benefits is that it can look fresh even in high summer temperatures.

When selecting a site for planting, consider how tall dill plants will grow. Because of their size, these plants make a good middle or back border for vegetable, ornamental, annual beds or culinary herb gardens.

Soil requirements

Amend the soil to a well-draining, moderately fertile soil. However, as many gardeners will agree, dill seeds can sprout just about anywhere and will grow in less-than-perfect conditions.

Water and fertilizer requirements

Dill plants grow best when the soil stays moderately moist. Plan regular deep watering by setting up drip irrigation or a soaker hose. Another alternative is to plant dill near other herbs with similar sun and water needs.

Like most herbs, a little fertilizer throughout the season helps plants stay healthy and productive.

Dealing with dill problems

Dill is one of the herbs that has few, if any, problems in the garden. Insect pests don’t seem to be attracted to the frilly leaves, and there aren’t any disease issues.

Plants grown in shady conditions may tend to lean, but staking them will prevent this problem.

Growing dill in pots

Dill makes a lovely plant for large patio containers. Be sure to use a high-quality potting soil mix for good drainage. The compact, dwarf dill varieties are perfect for containers and raised beds. Other taller types may outgrow their space.

How to harvest dill

Clip and use fresh dill leaves when plants are about 10 inches tall. Store fresh dill leaves in a plastic bag in the refrigerator. To freeze and save for later, chop finely and mix with water and fill ice cube trays.

Dry dill leaves, often called dill weed, by snipping stalks and drying them on a screen or hanging them upside down in a warm, well-ventilated place to dry. Store dried leaves and seeds in an airtight container in a cool, dark place.

Leave a few plants standing to self-seed in the garden for next season.

How to use dill in the kitchen

Dill is a versatile herb. You can use fresh or dried leaves and the seeds, either whole or ground. Dill is one of the most popular herbs for its culinary uses, especially for making dill pickles.

Use dill’s fresh ferny fronds in dips, dressings, vinegars, sauces and cold soups; chicken, turkey, tuna, fish or other seafood dishes; omelets and other egg recipes; mix into cottage cheese, sour cream and mild cheeses; and tangy potato salads.

When cooking with fresh dill leaves, add them just before serving because they tend to lose flavor when cooked. Dried leaves aren’t as flavorful as fresh, so sprinkle them generously into recipes.

Dill seeds are more intensely flavored than the leaves and make a delicious addition to cakes and savory breads; braised cabbage, meat stews, rice and cooked root vegetables.

Fresh dill pairs well with other garden-grown vegetables, like these:

• Green beans
• Cabbage
• Carrots
• Cucumbers
• Potatoes
• Tomatoes

How to propagate dill

If you let plants go to seed in the garden, those that fall to the ground may self-seed for the next season. But you can plan to save these seeds instead.

When seed heads start to form at the end of the season, harvest the plant and dry with a paper bag over the seed heads to collect the seeds as they fall from the flowers.
