12 Aromatic Herbs to Plant in May for Summer Cooking

Freshly planted herbs in May bring the strongest flavor and scent to your summer cooking. When soil conditions warm and the last frost passes, it's the perfect time to begin your herb planting schedule with confidence. Selecting the right aromatic herbs to plant now means a season filled with crisp basil, woodsy rosemary, and citrusy lemon balm within arm’s reach of your kitchen. With the right care and timing, a culinary herbs garden becomes more than practical—it becomes a daily sensory reward.

12 Best Aromatic Herbs to Plant in May

Starting your herb planting schedule in May gives you the best chance to grow a productive, fragrant culinary herbs garden for summer. Warmer soil, longer daylight, and reduced frost risk create ideal conditions for planting aromatic herbs that bring bold flavors and scents to your meals. May planting helps your garden herbs establish roots before the heat of summer, ensuring consistent growth and strong harvests.

Each herb listed below grows well when planted in May and provides not only rich aromas but also valuable culinary uses. Whether you're planting in raised beds, patio containers, or kitchen windowsills, these selections offer flexibility, fragrance, and flavor. Each plant has distinct preferences and benefits that align with the needs of an intentional, well-timed herb planting schedule.

Basil: A Heat-Loving Summer Essential

Basil is one of the most aromatic herbs to plant when soil temperatures begin to hold above 60°F. Known for its sweet, peppery fragrance, basil performs best in full sun and well-draining soil enriched with compost. Direct sowing or transplanting young seedlings in May gives the plant time to develop lush foliage for frequent harvesting. Pinching off the tips of new growth encourages bushiness and delays flowering, which can cause the flavor to turn bitter. Genovese, Thai, and Lemon basil each offer unique aroma profiles for pesto, stir-fries, and infused oils.

Basil leaves are at their most fragrant just before the plant flowers. Frequent harvesting promotes stronger scent concentration while keeping the plant healthy. This herb requires consistent moisture, but soggy soil leads to root rot. Use mulch to help retain moisture and limit weeds around the base.

Thyme: Compact, Hardy, and Powerfully Fragrant

Thyme’s low-growing habit and tolerance for dry, rocky soil make it a practical addition to any culinary herbs garden. Its small, leathery leaves release a strong, earthy scent that intensifies with heat and light. May is ideal for transplanting established seedlings or rooted cuttings outdoors, where they will quickly settle into the warming soil. Choose a location with excellent drainage and full sun, as wet roots can kill thyme quickly.

This herb needs minimal maintenance once established. Avoid overwatering and prune lightly after flowering to keep growth compact. Thyme complements roasted vegetables, poultry, and savory breads, making it a staple in both kitchen and garden.

Mint: Fast-Growing and Refreshingly Aromatic

Mint is one of the fastest-growing and most fragrant garden herbs to plant during May. With its unmistakable cool, sweet scent, mint is excellent for both culinary and medicinal uses. It prefers moist, slightly acidic soil and benefits from partial shade in hotter zones. Planting in containers helps contain its aggressive spreading habit, keeping your herb garden orderly.

There are many mint varieties—spearmint, peppermint, and chocolate mint—each with its own unique aroma and taste. Regular pruning encourages new, tender growth and prevents flowering, which can make the leaves tougher and less flavorful. Fresh mint enhances teas, fruit salads, chutneys, and sauces.

Dill: Fresh, Feathered, and Perfect for Pickling

Dill produces finely cut, feathery leaves with a bright, tangy scent that pairs well with summer produce. Planting dill directly in the soil in May ensures quick germination and strong early growth, especially in sunny areas with well-draining soil. This herb grows quickly and can reach heights over two feet, so thin seedlings and stake taller plants to avoid flopping.

Both dill leaves (dill weed) and seeds are used in cooking. Harvest the foliage when it's young and tender, as older leaves lose their softness. Use dill in pickling, creamy dressings, and light seafood dishes for a fresh flavor boost. Let a few plants flower if you want to collect seeds for spice or replanting.

Rosemary: Woodsy Aroma and Evergreen Flavor

Rosemary offers a strong, woodsy scent with notes of pine and citrus, perfect for hearty dishes like roasted potatoes or grilled lamb. It prefers dry, sandy soil and full sun exposure. May is a good time to transplant cuttings or young nursery plants into your garden, as the soil is warm enough for root development.

Water rosemary deeply but infrequently, allowing the soil to dry out between waterings. It does best in raised beds or containers with excellent drainage. Avoid overhead watering to prevent fungal issues. This herb also benefits from occasional pruning to encourage airflow and shape the plant. Over time, rosemary becomes a woody, evergreen shrub with long-lasting culinary value.

Cilantro: Quick to Grow and Bold in Flavor

Cilantro grows quickly and is packed with sharp, citrusy notes used in salsa, chutneys, and curries. Plant cilantro seeds directly in the garden in May to take advantage of cooler spring nights, which slow bolting. Once the heat intensifies, the plant begins to flower and set seed, reducing leaf production.

To extend your harvest, sow new seeds every two weeks for a continuous supply. Cilantro prefers loose, well-drained soil and full sun to partial shade. Harvest leaves early in the morning when the oils are most concentrated. When the plant bolts, you can also collect coriander seeds for seasoning or future planting.

Sage: Velvety Leaves with a Strong, Earthy Scent

Sage is prized for its gray-green, soft leaves that hold a deep, savory aroma. It thrives in well-draining soil and full sun, making May the best time to transplant young plants into the garden. Allow the soil to dry out between waterings, as sage is drought-tolerant and dislikes wet roots.

Once mature, sage can be harvested often throughout the growing season. Cut sprigs just above a leaf node to encourage branching and fuller growth. Use sage in stuffing, pasta dishes, and herb butters. The scent intensifies as the plant ages, making it a standout in both fresh and dried form.

Oregano: Mediterranean Flavor for Heavy Summer Meals

Oregano adds a robust, slightly bitter taste to tomato sauces, roasted vegetables, and grilled meats. It grows well in poor soil and hot conditions, which makes it one of the best aromatic herbs to plant in May. Transplant oregano seedlings outdoors after the last frost date for quick establishment.

Allow oregano to spread naturally or keep it trimmed to encourage compact, bushy growth. The essential oils are strongest just before flowering, so harvest regularly for peak aroma. Oregano also dries well, retaining its flavor for use throughout the year.

Chives: Mild Onion Notes with a Decorative Touch

Chives offer a delicate onion aroma and grow well when planted or divided in May. These thin, tubular leaves are easy to grow and provide continuous harvests through summer. Chives do best in full sun and fertile, well-draining soil. Regular watering supports lush growth, and cutting back the leaves frequently keeps the plant productive.

The purple blossoms are also edible and make a colorful addition to salads or compound butters. Chives are ideal for garnishing eggs, baked potatoes, and creamy sauces. This herb can be grown easily in pots or among vegetables to deter pests.

Tarragon: Anise-Infused Herb for Gourmet Touches

Tarragon has a licorice-like scent and flavor that enhances chicken, fish, and light sauces. French tarragon does not grow from seed, so May is the right time to transplant root divisions or nursery starts. Choose a sunny location with well-drained, slightly sandy soil for best results.

Water regularly but avoid soggy soil. Tarragon appreciates airflow and spacing, so avoid crowding it among other herbs. Harvest young stems regularly to maintain flavor and stimulate growth. It works especially well in cream-based recipes and vinaigrettes.

Lemon Balm: Citrus-Scented and Bee-Friendly

Lemon balm brings a lemony, mint-like scent to your herb garden. It performs well when planted in May, especially in spots with partial sun and rich, moist soil. This plant spreads aggressively, so growing in containers is often recommended. Regular pruning prevents it from overtaking nearby plants and encourages fuller leaf production.

Use fresh lemon balm leaves in herbal teas, salad dressings, or summer desserts. Their scent and flavor are strongest just before flowering. It also acts as a natural pest repellent and attracts pollinators, supporting the health of your broader culinary herbs garden.

Parsley: Versatile Garnish with Fresh, Mild Aroma

Parsley provides a clean, grassy scent that brightens up rich or salty dishes. Sow seeds directly in May, though germination may take up to three weeks. Choose a site with loose, fertile soil and keep it consistently moist until seedlings emerge. Once established, parsley requires only moderate maintenance.

Use flat-leaf parsley for stronger flavor and curly varieties for decorative purposes. Regular harvesting promotes steady growth, and cutting from the outer stems preserves the plant's core. Parsley is essential for finishing plates, blending into sauces, and balancing bold flavors.

Each of these herbs supports a productive and fragrant culinary herbs garden when planted at the right time. May offers ideal growing conditions to meet your herb planting schedule, setting you up for fresh, flavorful cooking all summer long.

Tips for Growing a Fragrant Culinary Herb Garden

A fragrant culinary herbs garden starts with proper planning and consistent care. Selecting the right herbs is only the first step. Their full aroma and flavor develop when soil, light, watering, and harvesting routines align with each plant’s unique needs. The following essential tips help support your herb planting schedule and enhance the overall scent and quality of your herbs.

Each suggestion below targets key care principles for aromatic herbs to plant in May, helping you create a garden that is both functional and aromatic through the growing season.

• Choose a sunny location: Herbs need at least 6 hours of direct sun. Most fragrant garden herbs like basil, thyme, and rosemary rely on full sunlight to develop their essential oils. Limited sun exposure results in leggy plants with dull flavors. A south-facing raised bed or balcony planter can provide reliable light for a strong start.

• Use well-draining, nutrient-rich soil: Good soil is essential for healthy root systems. Amend heavy or clay-rich soil with compost or coarse sand to improve drainage. Container herbs benefit from a mix formulated for vegetables or flowers. Avoid soggy soil, which promotes root rot and reduces plant aroma.

• Water deeply, but not too often: Overwatering is one of the most common issues in herb gardening. Most culinary herbs prefer to dry out slightly between waterings. Water at the base in the morning to prevent mildew and allow moisture to reach the roots without encouraging fungal problems on the leaves.

• Pinch and prune regularly to encourage bushy growth: Regular harvesting isn't just for cooking—it supports fuller plants and stronger scents. Pinching back basil, mint, and sage encourages side shoots, which increases leaf production and improves airflow. Remove flower buds unless seed production is a goal, as flowering can shift energy away from leaf development.

• Group herbs with similar care needs: Some herbs prefer drier soil (like oregano and rosemary), while others need more moisture (like parsley and cilantro). Grouping herbs with similar water and sunlight preferences makes it easier to maintain consistent care, preventing overwatering or stress.

• Fertilize lightly to maintain flavor concentration: Too much fertilizer can make herbs grow quickly but weaken their flavor and aroma. Use a balanced, organic fertilizer once a month, or side-dress with compost mid-season. Avoid high-nitrogen fertilizers, which promote foliage at the expense of essential oil production.

• Use mulch to retain moisture and suppress weeds: A light layer of straw, bark, or shredded leaves helps regulate soil temperature and keeps roots from drying out. Mulching also limits weed growth, allowing your herbs to receive more nutrients and water without competition.

Each of these practices helps improve the quality, fragrance, and productivity of your herb garden. Building a successful culinary herbs garden goes beyond planting—it’s a consistent process of thoughtful care based on the individual requirements of each aromatic herb. These tips bring structure and clarity to your herb planting schedule, making sure that flavor and fragrance go hand in hand all season long.

Delicious Ways to Use Summer Herbs in Cooking

Using freshly harvested herbs is one of the simplest ways to elevate summer meals with real flavor and aroma. When aromatic herbs to plant in May reach maturity, their oils and fragrance are at their peak—perfect for adding depth to everything from fresh salads to grilled meats. Timing your harvest and knowing how to match herbs with ingredients ensures you’re getting the most out of your culinary herbs garden.

Basil: Fresh and Versatile for Summer Dishes

Basil pairs well with tomatoes, mozzarella, and olive oil, offering a peppery sweetness that enhances simple dishes like Caprese salad. It's a go-to herb for pasta sauces, adds cooling contrast in spicy curries, and makes a vibrant pesto that stores easily. Tear basil over pizza or toss it into a salad just before serving to preserve its flavor and aroma. Always harvest before the plant flowers to capture its fullest fragrance.

Mint: Cooling Notes for Sweet and Savory Recipes

Mint’s crisp, refreshing flavor works well in both sweet and savory applications. Add it to cucumber salads, blend it into yogurt sauces, or use it to brighten fruit-based desserts. It also complements lamb dishes and brings a cooling twist to iced teas and lemonades. Use young leaves for the best texture and taste, and prune regularly to promote continuous new growth.

Thyme: Earthy Flavor That Holds Up to Heat

Thyme’s small leaves deliver an earthy, slightly floral flavor that stands up well to roasting and simmering. It enhances vegetables, stews, and meats without overpowering other ingredients. Add thyme sprigs whole to roasts or strip the leaves for marinades. Its concentrated oils remain potent even after extended cooking.

Rosemary: Bold Aroma for Grilled and Roasted Foods

Rosemary offers a piney, citrus-forward fragrance perfect for heavier dishes. Tuck sprigs into roasting pans with chicken or potatoes, or infuse into olive oil for bread dipping. Its woody stems can also be used as skewers for grilling, adding flavor from the inside out. Trim it regularly to keep its shape and encourage tender new shoots.

Cilantro: Fresh Top Notes for Bright Finishes

Cilantro’s sharp, citrusy taste adds freshness to salsas, noodle bowls, and stir-fries. It should be added at the end of cooking or used raw to keep its bright flavor intact. Chop both leaves and stems to reduce waste and get the most from each harvest. It's ideal for warm-weather dishes that benefit from a crisp herbal finish.

Parsley: Subtle Herb for Balance and Freshness

Flat-leaf parsley works as both a garnish and a main flavor in sauces like chimichurri or tabbouleh. Its mild, slightly peppery taste complements lemon and garlic, making it useful in grains, seafood, and roasted vegetables. Curly varieties offer more visual appeal while still contributing fresh notes. Frequent cutting helps maintain strong, leafy growth.

Sage: Strong Flavor for Rich, Cooked Dishes

Sage has a deep, resinous aroma that shines in brown butter sauces and stuffing. It’s especially effective when fried or slowly cooked, allowing the oils to develop. Add to pasta, roasted squash, or poultry, and use sparingly, as its flavor is bold. Fresh sage leaves can also be dried for later use without much loss of strength.

Oregano: Robust and Mediterranean in Profile

Oregano stands up well in tomato sauces, grilled meats, and oil-based dressings. While often dried, fresh oregano brings a more pronounced aroma and complexity. Sprinkle over pizza, stir into marinades, or blend with lemon and olive oil for quick vinaigrettes. Harvest regularly to prevent flowering and maintain leaf production.

Chives: Delicate Onion Notes for Finishing Touches

Chives provide a subtle onion flavor that works well in creamy dips, eggs, and baked potatoes. Add fresh, chopped chives to hot dishes just before serving to preserve their light scent. Their purple blossoms are edible and make a decorative topping or ingredient for infused vinegars.

Dill: Light and Citrusy for Pickling and Seafood

Dill's fern-like leaves are best used fresh in yogurt sauces, fish dishes, and potato salads. It also makes an ideal herb for homemade pickles and compound butters. Dill seeds can be harvested later for spice blends. Keep the plant trimmed to encourage continued foliage growth through the season.

Tarragon: Anise-Like Flavor for Gourmet Uses

Tarragon offers a licorice-like taste that pairs well with eggs, chicken, and creamy sauces. It also blends well with vinegar for tarragon-infused dressings or mustards. French tarragon should always be used fresh, as the dried version loses much of its distinctive scent. Harvest leaves regularly for consistent flavor.

Lemon Balm: Bright Citrus Notes for Light Dishes and Drinks

Lemon balm’s zesty aroma adds lift to fruit salads, sorbets, and teas. It can be infused into syrups or blended into vinaigrettes for a citrusy twist. This herb is also a natural companion to herbs like mint in cold drinks. Pick leaves just before flowering for the highest oil content and best flavor.

Each of these fragrant garden herbs plays a role in shaping flavorful summer meals. Used properly, they add complexity without overpowering other ingredients, letting you build dishes that reflect the freshness of your garden throughout the season.
