Georgia’s warm climate supports year-round growth of basil, mint, and lemon balm, but Florida’s summer heat and humidity are a different beast entirely. If you are looking for the best herbs to grow in florida summer, you need plants that thrive in intense sun, heavy rain, and high humidity. This guide covers the top herbs that will not just survive but flourish in your Florida garden from June through September.
Florida summers are brutal for many plants. Temperatures regularly hit the mid-90s, and afternoon thunderstorms dump inches of rain in minutes. But some herbs actually love this weather. They come from tropical or subtropical regions and are built for heat and moisture. Let’s get into the list.
Best Herbs To Grow In Florida Summer
These herbs are proven winners for the Sunshine State’s toughest season. They handle the heat, resist fungal diseases common in humidity, and keep producing leaves even when other plants bolt or rot. Each one has specific care tips to maximize your harvest.
Basil: The Heat Loving Champion
Basil is the undisputed king of Florida summer herbs. It grows fast, smells amazing, and loves the heat. Sweet basil, Genovese basil, and Thai basil all do exceptionally well. Plant them in full sun with good air circulation.
- Plant in raised beds or containers for better drainage
- Water deeply every morning, not at night
- Pinch off flower buds to keep leaves coming
- Harvest from the top down to encourage bushiness
One common problem with basil in Florida is downy mildew. This fungal disease shows up as yellow leaves with fuzzy gray spores underneath. To avoid it, choose resistant varieties like ‘Prospera’ or ‘Eleonora’. Space plants at least 12 inches apart so air can move freely between them.
Mint: The Invasive But Reliable Herb
Mint is almost impossible to kill in Florida summers. It spreads aggressively, so always grow it in a container or a sunken pot. Spearmint, peppermint, and chocolate mint all thrive. The heat actually makes the oils stronger, so your mint will taste more intense.
Mint prefers partial shade in Florida. Full afternoon sun can scorch the leaves. Give it morning sun and afternoon shade for best results. Keep the soil consistently moist but not waterlogged. Mint will tell you it needs water by drooping dramatically, then perk back up within hours of watering.
Lemongrass: The Tropical Powerhouse
Lemongrass is a grass, not a true herb, but it is essential for Florida gardens. It grows huge in the summer, reaching 4 to 6 feet tall. It repels mosquitoes naturally and adds a citrusy flavor to teas and stir-fries. Plant it in full sun and watch it take off.
- Buy starter plants from a nursery, not seeds
- Plant in well-draining soil or large containers
- Water deeply twice a week during dry spells
- Cut stalks at the base when they are pencil-thick
- Divide clumps every 2 years to keep them healthy
Lemongrass is drought tolerant once established. It also handles Florida’s rainy season well because it evolved in monsoon climates. The only thing it cannot tolerate is freezing temperatures, but summer is not a concern for that.
Rosemary: The Drought Tolerant Survivor
Rosemary loves Florida’s dry spells but hates wet feet. It is a Mediterranean herb that needs excellent drainage. In summer, the key is to plant it in sandy soil or a container with lots of perlite. Do not overwater it.
Rosemary grows best in full sun with at least 6 hours of direct light. It is naturally pest resistant and deer wont touch it. The biggest threat is root rot from too much rain. If you are planting in ground, mound the soil up 6 inches to improve drainage. For containers, use a cactus or succulent mix.
Oregano: The Low Maintenance Workhorse
Oregano is another Mediterranean herb that does well in Florida summers if you give it the right conditions. It needs full sun and very well-drained soil. Greek oregano is the most flavorful variety for cooking.
Oregano actually becomes more aromatic in heat. The leaves get oilier and more potent. Harvest it in the morning after the dew dries for the strongest flavor. Cut stems back by half every few weeks to keep the plant compact and productive.
Thai Basil: The Heat Tolerant Alternative
Thai basil is different from sweet basil. It has purple stems, smaller leaves, and a licorice-anise flavor. It handles Florida’s humidity much better than sweet basil and rarely gets downy mildew. It is a staple in Southeast Asian cooking.
- Grows best in full sun to partial shade
- Needs consistent moisture but not soggy soil
- Harvest leaves regularly to prevent flowering
- Use in stir-fries, curries, and pho
Thai basil is more heat tolerant than sweet basil and will keep producing well into September. It also attracts beneficial insects like bees and butterflies to your garden.
Chives: The Cool Season Herb That Adapts
Chives are usually a cool season herb, but they can survive Florida summers if planted in partial shade. They prefer morning sun and afternoon shade. Garlic chives are even more heat tolerant than regular chives.
Chives grow from bulbs and go dormant in extreme heat. To keep them going, mulch the soil heavily to keep roots cool. Water them regularly. If they die back in August, do not worry. They will come back when temperatures cool in October.
Dill: The Short Lived Summer Herb
Dill is tricky in Florida summers because it bolts quickly in heat. But you can still grow it if you plant it in partial shade and keep the soil cool. Dill attracts swallowtail butterfly caterpillars, so it is great for pollinators.
Sow dill seeds directly in the garden every 3 weeks for a continuous harvest. It grows fast and goes to seed in about 8 weeks. Use the leaves fresh and let some plants go to seed for pickling or replanting.
Cilantro: The Summer Challenge
Cilantro is the most difficult herb to grow in Florida summer. It bolts immediately in heat. But there is a trick: use slow bolt varieties like ‘Santo’ or ‘Calypso’. Plant it in deep shade where it gets only morning light.
Even with these tricks, cilantro will only last a few weeks in summer. Plan to replant every 2 weeks for a steady supply. Alternatively, grow culantro, which is a different plant that tastes like cilantro but thrives in heat. Culantro is a game changer for Florida gardeners.
Culantro: The Cilantro Substitute
Culantro looks nothing like cilantro. It has long, serrated leaves that grow in a rosette. But it tastes exactly like cilantro and loves Florida’s heat and humidity. It is a perennial in Florida and will come back year after year.
Plant culantro in partial shade with rich, moist soil. It grows slowly at first but takes off once established. Harvest outer leaves as needed. The flavor is stronger than cilantro, so use less in recipes.
How To Care For Herbs In Florida Summer
Growing herbs in Florida summer requires specific strategies. The heat, rain, and humidity create challenges you do not face in other climates. Here are the most important care tips.
Watering Wisely
Water in the morning only. Night watering leads to fungal diseases. Use drip irrigation or soaker hoses to keep water off the leaves. Wet leaves in humid weather invite mildew and rot.
Check soil moisture by sticking your finger an inch deep. If it feels dry, water. If it feels wet, wait. Overwatering is more common than underwatering in Florida summer.
Soil And Drainage
Florida soil is mostly sand. It drains fast but holds few nutrients. Amend your soil with compost, peat moss, or coconut coir to improve water retention. For Mediterranean herbs like rosemary and oregano, add extra perlite or sand to ensure drainage.
Raised beds are ideal for Florida summer gardening. They warm up faster in spring, drain well in summer, and keep roots above waterlogged ground. Build them at least 12 inches tall.
Sunlight Management
Full sun in Florida is intense. Many herbs benefit from afternoon shade, especially during July and August. Use shade cloth or plant taller crops on the west side of your herb garden to block the harshest rays.
Observe your garden throughout the day. Areas that get morning sun and afternoon shade are perfect for most herbs. Full sun works for basil, lemongrass, and rosemary if you water them enough.
Fertilizing
Herbs do not need heavy fertilizer. Too much nitrogen makes them grow soft, leafy growth that attracts pests. Use a balanced, slow release fertilizer once at planting time. Then side dress with compost every 6 weeks.
Liquid seaweed or fish emulsion applied monthly gives herbs a gentle boost. Avoid synthetic fertilizers that burn roots in hot weather.
Pest Control
Florida summer brings aphids, spider mites, whiteflies, and caterpillars. Inspect your herbs every few days. Spray off small infestations with a strong jet of water. Use neem oil for persistent problems, but apply it in the evening to avoid burning leaves.
Encourage beneficial insects like ladybugs and lacewings by planting flowers nearby. Marigolds, zinnias, and sunflowers attract predators that eat pests.
Best Practices For Harvesting
Harvesting correctly keeps your herbs productive all summer. Here are the rules.
- Harvest in the morning after dew dries but before heat peaks
- Use clean, sharp scissors or pruners
- Never harvest more than one third of the plant at once
- Cut above a leaf node to encourage branching
- Remove flower buds immediately to keep leaves growing
Regular harvesting is the secret to bushy, productive plants. If you let herbs flower and go to seed, they stop producing leaves. Stay on top of it.
Container Gardening For Florida Summer
Containers are often better than in ground planting for Florida summer herbs. You can control soil quality, drainage, and sun exposure. Plus, you can move pots to follow shade or avoid storms.
Use terracotta or ceramic pots that breathe. Plastic pots hold too much heat and moisture. Make sure each pot has drainage holes. Elevate pots on bricks or pot feet to keep them out of standing water.
Group pots together to create a microclimate with higher humidity. This helps moisture loving herbs like mint and basil. But leave space between groups for air circulation.
Common Problems And Solutions
Even with the best care, Florida summer herbs face issues. Here are the most common ones and how to fix them.
Yellow Leaves
Yellow leaves usually mean overwatering or nutrient deficiency. Check drainage first. If the soil is soggy, let it dry out. If drainage is fine, add a balanced liquid fertilizer.
Leggy Growth
Leggy, stretched out growth means not enough light. Move your herbs to a sunnier spot or prune them back hard to encourage compact growth. Pinch off the top two sets of leaves every week.
Fungal Spots
Black or brown spots on leaves are fungal infections. Remove affected leaves immediately. Improve air circulation by spacing plants further apart. Water at soil level, not overhead.
Wilting In Heat
Some wilting in the afternoon heat is normal, even for well watered plants. If the plant recovers by evening, it is fine. If it stays wilted, check soil moisture. It may need water or have root rot.
Frequently Asked Questions
What herbs grow best in Florida summer heat?
Basil, lemongrass, mint, Thai basil, and culantro are the top performers. They are native to tropical climates and handle heat and humidity well.
Can I grow rosemary in Florida summer?
Yes, but it needs excellent drainage. Plant it in sandy soil or a container with cactus mix. Do not overwater it. It prefers full sun but can handle some afternoon shade.
Why does my cilantro die so fast in summer?
Cilantro bolts in heat. It is a cool season crop. Use slow bolt varieties and plant in deep shade. Or switch to culantro, which tastes similar but thrives in summer.
How often should I water herbs in Florida summer?
Most herbs need water every day or every other day during summer. Check soil moisture daily. Water deeply in the morning. Adjust based on rainfall and temperature.
What is the easiest herb to grow in Florida summer?
Lemongrass is the easiest. It grows fast, needs little care, and repels mosquitoes. Mint is also very easy but must be contained in a pot.
Final Tips For Success
Start with healthy plants from a local nursery. They are already acclimated to Florida conditions. Seeds are harder to germinate in summer heat. Buy transplants for instant results.
Mulch your herbs with straw or wood chips. Mulch keeps soil cool, retains moisture, and suppresses weeds. Apply a 2 inch layer around each plant, but keep it away from the stems.
Be patient with slow starters. Some herbs take a few weeks to establish roots before they start growing fast. Give them time and consistent care.
Grow what you actually use. There is no point in planting five types of mint if you only drink peppermint tea. Focus on herbs you cook with or use for teas and remedies.
Share your harvest with neighbors. Florida summer herbs grow so fast that you will have more than you can use. Basil, mint, and lemongrass make great gifts.
Keep a garden journal. Note what worked and what did not. Florida summers vary from year to year. Your observations will help you improve every season.
With these herbs and tips, you can have a productive herb garden all summer long. The key is choosing the right plants and giving them the care they need. Start with basil and lemongrass for guaranteed success. Add mint and culantro for variety. Your Florida summer herb garden will be the envy of the neighborhood.
