There’s something alchemical about brushing past a row of herbs on your windowsill and releasing a burst of fragrance that instantly transports you to a Mediterranean hillside or a Provençal market. Growing fragrant herbs from seed transforms not just your cooking, but the very atmosphere of your kitchen. Unlike mature plants from the garden center, seeds allow you to nurture herbs specifically selected for flavor intensity, compact growth habits, and suitability for indoor conditions. The journey from tiny seed to aromatic harvest creates a relationship with your ingredients that elevates everyday cooking into something extraordinary.
Your kitchen windowsill offers a unique microclimate—warmth from cooking, humidity from the sink, and light that’s often more consistent than outdoor gardens. With the right seed varieties and a few insider techniques, you can create a year-round supply of culinary aromatics that put dried spices to shame. Let’s explore how to choose and grow the most fragrant herb seeds for your indoor garden.

6. BUZZY Seeds Organic Windowsill Grow Kit, Copper Culinary Herb Garden with Basil, Cilantro and Chives, Indoor Starter Set with Seed Packets and Growing Medium, Holiday Present, Gardening Gift
Overview: The BUZZY Seeds Organic Windowsill Grow Kit delivers a curated indoor herb experience with its striking copper planter and three organic seed varieties. Designed for kitchen counters and windowsills, this kit includes basil, cilantro, and chives seeds plus coconut husk growing medium. It’s positioned as a premium entry-level solution for health-conscious cooks and gift-givers who value both aesthetics and organic certification.
What Makes It Stand Out: The genuine copper planter elevates this beyond typical plastic kits, creating a reusable decorative piece that ages beautifully. The certified organic seeds appeal to purists, while the pre-measured coconut husk medium eliminates guesswork. Its compact 11.25" x 4.25" footprint fits virtually any sunny spot, making fresh herbs accessible year-round without outdoor space.
Value for Money: At $16.49, you’re paying for design and organic certification rather than sheer volume. The reusable copper vessel justifies the premium over disposable kits. Compared to buying $3-4 organic herb bunches weekly, this kit pays for itself within a month of successful harvests. However, experienced gardeners might find better value in bulk seed purchases.
Strengths and Weaknesses: Strengths include the gorgeous copper planter, true organic seeds, foolproof instructions, and compact design. Weaknesses are limited to three herb varieties, small growing capacity requiring eventual transplanting, and the copper’s tendency to tarnish. The coconut medium works well but dries faster than soil.
Bottom Line: Perfect for apartment dwellers, novice gardeners, and as a sophisticated housewarming gift. The BUZZY kit prioritizes style and simplicity over variety, making it ideal for those who want fresh herbs without complexity. If you value organic certification and aesthetics, this delivers reliable results with minimal effort.
7. Meekear 10 Kit Non-GMO Growing into Thyme, Lavender, Chamomile, Dill, Chives, Cilantro, Rosemary, Basil, Parsley, Sage Indoor/Outdoor for Kitchen Windowsill Gardening Gift
Overview: The Meekear 10 Kit offers an unprecedented variety of heirloom herbs at a budget price point. For under $9, you receive seeds for thyme, lavender, chamomile, dill, chives, cilantro, rosemary, basil, parsley, and sage. This no-frills package focuses on seed diversity rather than fancy containers, targeting cost-conscious gardeners who want maximum options.
What Makes It Stand Out: Ten distinct herb varieties for less than a dollar each is remarkable value. The 100% heirloom, non-GMO seeds promise higher germination rates and seed-saving potential. This kit acknowledges gardening reality with honest germination timelines (2-8 weeks) and practical soaking recommendations, appealing to experienced beginners who appreciate transparency.
Value for Money: At $8.99, this is arguably the best price-per-variety ratio available. You’re getting a comprehensive culinary and medicinal herb collection for the cost of two store-bought herb plants. The lack of planters or soil keeps costs low, though you’ll need to invest in separate growing supplies.
Strengths and Weaknesses: Strengths include incredible variety, heirloom genetics, low cost, and versatile uses from cooking to tea-making. Weaknesses are the absence of growing medium or containers, vague instructions for true beginners, and extended germination periods requiring patience. Some herbs like rosemary naturally have lower germination rates.
Bottom Line: Best suited for gardeners with basic supplies and knowledge. If you’re willing to provide your own pots and soil, this kit offers unmatched variety for experimentation. It’s an excellent choice for classrooms, hobbyists wanting to try multiple herbs, or anyone prioritizing quantity over convenience.
8. BUZZY Seeds 2-Pack Windowsill Grow Kits, Strawberry and Organic Herb Gardening Set with Basil, Cilantro, Chives, Non-GMO Seeds, Growing Medium and Planters, Housewarming Gift Idea
Overview: BUZZY Seeds’ 2-Pack kit cleverly combines strawberry and herb gardening in one affordable package. For $16.49, you get two windowsill planters—one for strawberries and one for basil, cilantro, and chives—plus coconut husk medium and non-GMO seeds. This dual approach offers more variety than single kits while maintaining beginner-friendly simplicity.
What Makes It Stand Out: The strawberry addition distinguishes this from standard herb kits, providing both visual interest and edible fruit. Getting two complete growing systems for the price of one premium single kit creates immediate value. The separate planters prevent cross-contamination and allow different care schedules for fruit versus herbs.
Value for Money: Matching the price of BUZZY’s single copper kit, this offers double the growing potential. While strawberries require more patience than herbs, the combined harvest potential significantly increases ROI. The reusable planters provide ongoing value for future growing seasons.
Strengths and Weaknesses: Strengths include the strawberry-herb combination, two reusable planters, non-GMO seeds, and excellent price-to-content ratio. Weaknesses involve strawberries’ longer timeline and higher care requirements, smaller seed quantities than dedicated kits, and plastic planters that lack the aesthetic appeal of copper alternatives.
Bottom Line: An outstanding choice for gift-givers and curious beginners wanting maximum variety. The strawberry addition makes this more engaging for families with children. If you’re deciding between herb kits, this two-pack delivers superior value and interest, though strawberry success requires more attention than the nearly foolproof herbs.
9. Meekear 5 Herb Seeds Garden Starter Kit with Complete Planting Kit & Wooden Flower Box, Growing into Basil, Parsley, Rosemary, Thyme, Mint for Kitchen Windowsill Herb Garden DIY
Overview: Meekear’s 5-herb kit positions itself as a premium starter package with its wooden planter box and comprehensive tool set. At $26.99, it includes basil, parsley, rosemary, thyme, and mint seeds, plus jute bags, soil discs, markers, mini tools, and a water bottle. This is designed for serious beginners who want a complete, gift-worthy solution.
What Makes It Stand Out: The rustic wooden box provides a stable germination environment while serving as attractive kitchen decor. Five biodegradable jute bags simplify transplanting and prevent wood damage. The inclusion of actual gardening tools—not just stickers—demonstrates thoughtful design for hands-on learning.
Value for Money: The higher price reflects the wooden container and tool set rather than seed quantity. While nearly triple the cost of basic kits, it eliminates separate supply purchases. The wooden box has limited long-term use (requires transplanting at 2-3 inches), but the tools provide lasting value.
Strengths and Weaknesses: Strengths include the premium wooden presentation, complete tool kit, biodegradable jute bags, and coconut coir soil discs. Weaknesses are the high price for only five varieties, wooden box’s size limitations, and potential cracking if soil is added directly. The kit may overwhelm absolute beginners with its many components.
Bottom Line: Ideal as a thoughtful gift or for beginners wanting a professional start. The wooden aesthetic suits modern farmhouse kitchens perfectly. If you value presentation and having all necessary tools included, the premium is justified. However, budget-conscious buyers can achieve similar results for less.

Strengths and Weaknesses: Strengths include massive variety, huge seed count, hydroponic versatility, heirloom genetics, and excellent packaging. Weaknesses are the lack of growing supplies, potential overwhelm for beginners, and no included instructions for specific varieties. Some herbs require stratification or have naturally lower germination.
Bottom Line: The ultimate choice for committed gardeners, hydroponic enthusiasts, and budget-savvy cooks. This isn’t a casual gift kit—it’s a long-term gardening investment. Perfect for those with existing supplies who want maximum variety. Beginners should pair it with a basic growing guide, but experienced growers will find unbeatable value.
The Transformative Power of Growing Herbs from Seed
Starting herbs from seed gives you access to hundreds of varieties bred for specific flavors and growth characteristics that nursery starters rarely offer. When you control the entire growing process, your plants adapt to your exact light conditions and harvesting style from day one.
Why Seeds Trump Seedlings for Windowsill Gardens
Seed-grown herbs develop stronger root systems in their permanent containers, avoiding the transplant shock that weakens many store-bought plants. You’ll also bypass the synthetic fertilizers and growth regulators commonly used in commercial herb production, which can actually reduce essential oil concentration—the very compounds that give herbs their fragrance and flavor. Seeds cost pennies compared to $4-6 per plant, allowing you to experiment with unusual varieties like lemon basil or pineapple sage without financial risk.
Reading Your Kitchen’s Light Landscape
Before buying seeds, spend a few days observing your windowsill. South-facing windows provide the most intense light, perfect for Mediterranean herbs like basil and oregano. East windows offer gentle morning sun that prevents cilantro from bolting too quickly. West-facing sills work well for mint and chives, which appreciate afternoon brightness without scorching. If your only option is north-facing, don’t despair—many herbs adapt to bright indirect light, though you’ll need to adjust your variety selection toward shade-tolerant types like parsley and chervil.
Decoding the Seed Packet: An Expert’s Buying Guide
Seed packets contain a wealth of information if you know how to interpret the data. Understanding these details separates successful windowsill gardens from disappointing attempts.
Germination Rates: The 85% Gold Standard
Reputable seed companies list germination percentages tested within the last six months. Look for rates above 85% for reliable results. Lower percentages don’t mean the seeds are bad—some herbs like parsley naturally germinate at 70%—but they signal you should sow extra seeds to compensate. Always check the test date; germination drops significantly after two years, even in sealed packets.
Organic vs. Conventional: What Science Says
Organic seeds come from plants grown without synthetic pesticides or fertilizers, but this matters less for the home gardener than seed genetics. What truly impacts your indoor garden is whether seeds are untreated. Conventional seeds often receive fungicide coatings that can inhibit germination in indoor conditions. Look for “untreated” seeds regardless of organic certification—this ensures nothing interferes with the natural germination process on your windowsill.
Heirloom, Hybrid, and Open-Pollinated Explained
Heirloom herb seeds preserve centuries-old flavors and fragrances often lost in modern breeding. They’re perfect for windowsills because they were originally selected for home garden performance, not commercial shipping durability. Open-pollinated varieties offer similar benefits and allow you to save seeds from your own plants. Hybrids, while sometimes more vigorous, often produce sterile seeds and can have diluted essential oils bred out in favor of disease resistance.
The Importance of Days to Maturity
That “days to maturity” number determines your wait time for harvest. For windowsill gardens, prioritize herbs maturing in 60-75 days. Quick-growing cilantro and dill reward you within weeks, while slow-germinating parsley teaches patience but rewards with months of continuous harvest. Understanding this timeline helps you plan succession sowings so you never face a gap in fresh herbs.
Mediterranean Classics: Sun-Drenched Aromatics
These heat-loving herbs thrive in the warm, bright conditions most kitchen windowsills provide. Their robust essential oils concentrate when grown in containers with slight moisture stress.
Basil: The Cornerstone of Kitchen Fragrance
Basil seeds germinate reliably within 5-10 days, making them perfect for impatient gardeners. For windowsills, choose compact varieties that reach only 12-18 inches rather than the sprawling 3-foot garden types. The key to intense fragrance is warm soil—basil seeds won’t sprout below 70°F, so place them on top of your refrigerator or use a seedling heat mat. Once established, harvest by pinching just above leaf nodes to encourage branching. Never refrigerate harvested basil; the cold destroys cell structure and fragrance.
Oregano: The Pizza Herb’s True Potential
Greek oregano offers the most concentrated flavor, with seeds that produce plants whose leaves contain 3-4% essential oil by weight—significantly higher than shop-bought plants. Oregano seeds need light to germinate, so press them gently onto the soil surface without covering. They prefer slightly alkaline soil, so add a pinch of garden lime to your potting mix. The fragrance intensifies when you allow the soil to dry between waterings, mimicking Mediterranean hillside conditions.
Thyme: Tiny Leaves, Mighty Scent
Thyme seeds are microscopic and notoriously slow to germinate (14-28 days), but the wait rewards you with plants that live for years. Creeping thyme varieties stay under 6 inches tall, perfect for shallow windowsill containers. The secret to germination is freezing the seeds for 3-5 days before sowing—this cold stratification mimics winter conditions and breaks dormancy. Once growing, thyme needs excellent drainage; mix perlite into your soil at a 1:3 ratio.
Sage: The Velvety Aromatic
Common sage seeds develop into plants with soft, gray-green leaves that release their earthy scent at the slightest touch. Sage demands full sun and will become leggy even in bright windows without direct sunlight. Seeds germinate best with bottom heat and take 10-21 days to sprout. For windowsills, seek out dwarf varieties that remain compact. Sage’s fragrance peaks just before flowering—watch for bud formation and harvest heavily at that stage.
The Allium Family: Onion-Scented Essentials
These grass-like herbs provide subtle background notes that elevate dishes without dominating. Their quick germination makes them ideal for beginners.
Chives: First Sprouts of Spring
Chive seeds emerge in just 7-14 days, producing slender, hollow leaves with a delicate onion fragrance. They tolerate lower light than Mediterranean herbs, making them perfect for east-facing windowsills. The key to continuous production is the “cut-and-come-again” method—snip leaves to within an inch of the soil, and new growth appears within days. Chive flowers are edible and offer a beautiful purple display if you let a few plants bloom.
Garlic Chives: A Gentle Garlic Kiss
Despite the name, garlic chives aren’t just garlic-flavored chives—they’re a distinct species with flat leaves and white flowers. Their seeds germinate similarly to common chives but produce plants with a subtler, sweeter garlic aroma that doesn’t overpower delicate dishes. They prefer slightly moister soil than their onion-scented cousins and appreciate a monthly feeding with diluted fish emulsion.
Mint Family Marvels: Refreshing and Vigorous
Mint seeds develop into plants with aggressive root systems that can overrun containers, but proper management yields unparalleled freshness for beverages and desserts.
Spearmint vs. Peppermint: Culinary Distinctions
Spearmint seeds produce plants with a sweet, mild fragrance perfect for savory Middle Eastern dishes and mojitos. Peppermint seeds yield a more intense, menthol-rich plant better suited for teas and desserts. Both germinate in 10-15 days but require different care—peppermint tolerates partial shade, while spearmint needs more sun to develop full flavor. Always grow mint from seed rather than cuttings to avoid introducing soil-borne diseases to your indoor garden.
The Container Within a Container Method
Mint’s invasive nature requires special containment. Plant mint seeds in a 4-inch pot, then sink that pot into your decorative windowsill container. This barrier prevents underground runners from escaping while allowing you to lift the inner pot for harvesting and division. Repot annually, as mint exhausts soil nutrients quickly.
Unique Aromatics for Adventurous Palates
These herbs offer distinctive fragrances that expand your culinary repertoire beyond the usual suspects. They require slightly more attention but reward with complex flavors.
Cilantro and Coriander: The Two-Stage Wonder
Cilantro seeds (which are technically coriander seeds) give you two harvests from one plant. Sow seeds every 2-3 weeks for continuous leaf production, as cilantro bolts quickly in warm conditions. For maximum fragrance, crush the seeds lightly before sowing to crack the husk—this speeds germination from 14 days to 7-10. Once plants flower, let seeds mature; these coriander seeds have a completely different, citrusy fragrance perfect for spice blends.
Dill: Feathery Anise Notes
Dill seeds produce delicate, fern-like foliage with a bright, clean fragrance. For windowsills, choose ‘Fernleaf’ or ‘Bouquet’ varieties that stay under 18 inches. Dill develops a taproot, so use deeper containers (at least 8 inches). The fragrance intensifies when you stress the plant slightly—allow the top inch of soil to dry between waterings. Harvest the tender leaves before the plant flowers; once dill bolts, the foliage becomes bitter.
French Tarragon: The Anise-Scented Secret
Here’s a crucial note: true French tarragon rarely produces viable seeds. What seed companies sell as “tarragon” is typically Russian tarragon, which has a much milder flavor. For authentic French tarragon fragrance, you’ll need to purchase a plant. However, Russian tarragon seeds grow into decent plants for windowsills, offering a subtle anise note that works in salads and egg dishes. Germination is poor (50% at best), so sow thickly.
Lavender: Bringing Provence Indoors
English lavender seeds develop into plants with the classic sweet, floral fragrance, but they demand perfect conditions. Lavender seeds need cold stratification (4-6 weeks in the refrigerator) and light to germinate—a challenging combination. Start them in late winter for best results. Once established, lavender requires extremely sharp drainage; mix sand into your potting soil. Harvest flowers just as they open for the most intense essential oil concentration.
Setting Up Your Sill for Maximum Success
The right setup prevents 90% of windowsill herb problems before they begin. Invest time in proper containers and soil, and your seeds will practically grow themselves.
Pot Selection: Drainage is Non-Negotiable
Herbs despise wet feet. Choose containers with at least three drainage holes, and never use saucers that keep pots sitting in water. Terra cotta breathes better than plastic, preventing root rot, but dries out faster—perfect for Mediterranean herbs. For moisture-loving chives and mint, glazed ceramic retains consistent moisture. Container depth matters: shallow 4-inch pots suit thyme and oregano, while dill and parsley need 6-8 inches for root development.
The Perfect Soilless Seed Starting Mix
Never use garden soil for starting herb seeds—it compacts, retains too much moisture, and harbors diseases. Create your own mix: combine equal parts peat moss or coco coir, perlite, and vermiculite. This blend holds moisture while providing air pockets for delicate seedlings. For Mediterranean herbs, add 10% coarse sand to improve drainage further. Sterilize the mix by microwaving it damp for 90 seconds to kill any fungal spores.
Supplemental Lighting: When and What
Even the sunniest windowsill provides only 500-1000 foot-candles on a bright day, while herbs prefer 1500-2000. If seedlings become leggy or leaves look pale, add a full-spectrum LED grow light positioned 4-6 inches above the plants. Run lights for 14-16 hours daily, using a timer for consistency. The investment pays dividends in essential oil production and compact growth.
The Critical First Weeks: Seedling Care
The period between germination and true leaf formation determines your herb garden’s long-term success. Most failures happen during these delicate early days.
Watering Techniques: Bottom-Up Approach
Never water herb seedlings from above—the water pressure disturbs tiny roots and encourages fungal diseases. Instead, place pots in a shallow tray filled with 1/2 inch of water, allowing soil to wick moisture up from below. Remove pots once the surface feels moist, typically in 15-20 minutes. This method ensures even moisture distribution and encourages deep root growth.
The Art of Strategic Thinning
It’s heartbreaking, but necessary. Once seedlings develop their first true leaves (the second set, not the initial seed leaves), thin to one plant per 2-inch diameter of pot. Use scissors to snip unwanted seedlings at soil level rather than pulling them—this prevents disturbing the roots of neighboring plants. Proper spacing ensures adequate air circulation, preventing the dreaded damping-off disease.
Hardening Off: Even for Indoor Gardens
Seeds started in perfect indoor conditions need gradual acclimation to your windowsill’s actual conditions. Over a week, gradually increase exposure to direct sunlight and air movement. Start with 2 hours of morning sun, increasing by an hour daily. This prevents sunscald and prepares plants for the variable conditions they’ll face on your sill.
Ongoing Maintenance for Year-Round Harvests
Established herb plants follow simple care routines that differ from typical houseplants. Understanding these nuances keeps your windowsill productive for months.
The Pinching Technique for Fuller Plants
For most herbs, the secret to bushy growth is strategic pinching. When plants reach 4-6 inches tall, pinch out the growing tip just above a leaf node. This simple act redirects energy to side shoots, creating a full, compact plant instead of a tall, spindly one. With basil, pinch above the second set of true leaves for maximum branching. For oregano and thyme, pinch after flowering to encourage a second flush of growth.
Fertilizing Fragrant Herbs: Less is More
Herbs develop their strongest fragrances when slightly stressed. Fertilize only monthly at half the recommended strength, using an organic liquid fertilizer. Over-fertilized herbs grow large but lose essential oil concentration, resulting in bland flavor. Yellowing lower leaves signal true nutrient deficiency—add a light feeding. Dark green, lush growth with weak scent means you’re feeding too much.
Seasonal Adjustments for Year-Round Growth
Windowsill herbs experience seasons just like outdoor plants. In winter, reduce watering by 30% as growth slows. Increase light exposure by cleaning windows and removing screens. In summer, monitor for heat stress—windows can amplify temperatures above 85°F, causing premature bolting. A small fan improves air circulation and strengthens stems.
Troubleshooting Common Windowsill Challenges
Even experienced gardeners encounter problems. The key is early intervention and understanding that indoor herbs face different stressors than outdoor plants.
Leggy Seedlings: Prevention and Correction
Leggy growth indicates insufficient light. Immediately move plants closer to the window or supplement with grow lights. For mild cases, bury leggy stems deeper when repotting—herbs like basil and mint develop roots along buried stems. Rotate pots 180° every few days to prevent plants from leaning toward the light source.
Managing Aphids and Spider Mites Naturally
Indoor herbs attract pests despite the protected environment. At the first sign of aphids (clusters on new growth) or spider mites (fine webbing, stippled leaves), isolate the affected plant. Spray with a strong jet of water to dislodge pests, then apply insecticidal soap. For severe infestations, prune back the plant by two-thirds—herbs recover quickly from hard pruning. Never use chemical pesticides on edible plants.
When and How to Repot
Herbs need repotting when roots circle the bottom of the container or water runs straight through without absorbing. Choose a pot only 1-2 inches larger in diameter—too much soil holds excess moisture and causes root rot. Spring is ideal for repotting, but windowsill herbs forgive mid-winter transplanting if you reduce fertilizer and water for two weeks afterward.
Harvesting for Peak Flavor and Fragrance
The timing and technique of harvesting dramatically affect your herbs’ culinary impact. Develop a daily harvesting ritual that becomes as natural as brewing coffee.
Morning Harvesting Rituals
Essential oil concentration peaks in early morning after cool nights but before the sun’s heat causes oils to evaporate. Harvest between 6-10 AM for maximum fragrance. Use sharp scissors to make clean cuts that heal quickly. Never harvest more than one-third of the plant at once—this stresses the plant without killing it. Morning harvesting also gives plants the entire day to recover and produce new growth.
Preserving Your Bounty
When your windowsill produces more than you can use immediately, preserve the excess without losing fragrance. Freeze herbs like basil and cilantro in ice cube trays covered with olive oil—this captures the fresh flavor better than drying. For Mediterranean herbs, air-dry small bundles in a dark, well-ventilated area. Microwave drying works for thyme and oregano: place a single layer between paper towels and microwave in 30-second intervals until crisp.
Frequently Asked Questions
How long do herb seeds typically remain viable?
Most herb seeds maintain good germination rates for 2-3 years when stored properly in a cool, dark, dry location. Parsley and dill seeds lose viability faster, often after just one year. For best results, purchase fresh seeds annually and store them in an airtight container in your refrigerator.
Can I grow multiple herbs in one large windowsill container?
While tempting, mixed plantings often fail because herbs have different water and light needs. Mediterranean herbs prefer dry soil, while mint and chives like consistent moisture. Grow each herb in its own 4-6 inch pot, then group the pots in a larger decorative container for visual appeal while maintaining individual care.
Why do my herb seedlings keep dying after sprouting?
This is likely damping-off disease, caused by fungi that thrive in wet, poorly ventilated conditions. Prevent it by using sterile seed-starting mix, watering from below, ensuring good air circulation with a small fan, and avoiding overcrowding. A light dusting of cinnamon on the soil surface acts as a natural antifungal.
How much light do windowsill herbs really need?
Most culinary herbs need 6-8 hours of direct sunlight or 14-16 hours under grow lights. A south-facing window provides adequate light from March through September, but winter months require supplemental lighting. If you can’t read a book comfortably without artificial light at your windowsill, your herbs need grow lights.
Should I start herb seeds indoors year-round or wait for spring?
You can start seeds indoors any time, but winter sowing requires supplemental lighting and careful temperature management. Herbs germinate best when soil temperatures are 65-75°F. Starting seeds in late winter (February-March) gives you mature plants ready for heavy spring harvesting, while summer sowing provides fresh herbs for fall cooking.
Why are my herb leaves turning yellow?
Yellowing leaves signal several potential issues. Overwatering is the most common cause—allow soil to dry between waterings. Nutrient deficiency causes yellowing in older leaves first; feed lightly. If new growth is yellow with green veins, the soil pH is too high or low, locking out nutrients. Most herbs prefer slightly acidic soil (pH 6.0-7.0).
How do I know when to water my herb plants?
Stick your finger 1 inch into the soil. If it feels dry at that depth, water thoroughly until water drains from the bottom. For Mediterranean herbs, wait until the top 2 inches dry out. Weight is another indicator—lift the pot after watering to feel its heft; when it feels noticeably lighter, it’s time to water again.
Can I use seeds from grocery store spice jars?
Grocery store seeds are typically heat-treated or too old to germinate reliably. Some, like coriander and dill seeds, might sprout if they’re whole and untreated, but germination rates will be poor. Purchase seeds from reputable garden suppliers to ensure variety purity, high germination rates, and absence of chemical treatments.
What’s the best way to encourage my herbs to flower?
For most culinary herbs, flowering signals the end of peak leaf production and often reduces flavor intensity. Prevent flowering by regularly pinching growing tips. If you want seeds or edible flowers (like chive blossoms), allow a few plants to bolt. Harvest flowers immediately when they appear to prevent the plant from putting all energy into seed production.
How do I transition outdoor herbs indoors for winter?
Gradually acclimate plants over two weeks, bringing them inside overnight first. Inspect thoroughly for pests—aphids and spider mites hitchhike easily. Prune back by one-third to reduce stress and fit windowsill space. Place in the brightest window and reduce watering by half until you see new growth, indicating the plant has adjusted to indoor conditions.
