What To Know
- The best time to plant coriander in summer is during the cooler months, ideally early in the morning or late in the evening when temperatures are milder.
- If you live in a region with prolonged summer heat, consider starting your coriander indoors in the early spring and transplanting them outdoors once the weather cools down in the fall.
- You can collect the seeds from your plants and sow them in the fall for a new crop of coriander to enjoy in the cooler months.
Summer’s scorching sun and relentless heat can be a challenge for even the most seasoned gardener. But fear not, coriander lovers! While this delicate herb prefers cooler temperatures, with a little strategic planning and care, you can still enjoy a bountiful harvest even in the dog days of summer.
Understanding Coriander’s Summer Struggles
Coriander, also known as cilantro, is a cool-season annual that thrives in temperatures between 55-70°F. When the mercury climbs above 80°F, coriander plants tend to bolt, meaning they prematurely flower and produce seeds, resulting in a bitter, less flavorful foliage. Additionally, the intense sunlight can scorch the leaves, leading to wilting and stunted growth.
Choosing the Right Time to Plant
Timing is crucial for successful summer coriander cultivation. The best time to plant coriander in summer is during the cooler months, ideally early in the morning or late in the evening when temperatures are milder. If you live in a region with prolonged summer heat, consider starting your coriander indoors in the early spring and transplanting them outdoors once the weather cools down in the fall.
Selecting the Perfect Spot
Coriander thrives in a sunny location, but during the summer, it’s best to choose a spot that receives partial shade, especially in the afternoon. This will help protect the plants from the intense heat and prevent them from bolting too quickly.
Providing Ample Water
Coriander needs consistent moisture to flourish, especially during the summer. Water deeply and regularly, ensuring the soil remains moist but not waterlogged. Use a watering can or soaker hose to avoid splashing water onto the leaves, which can encourage fungal diseases.
Keeping the Soil Cool
One of the biggest challenges of growing coriander in summer is maintaining cool soil temperatures. Mulching around the plants with organic materials like straw or wood chips can help insulate the soil and prevent it from heating up too quickly.
Harvesting Your Summer Coriander
The key to harvesting coriander in summer is to pick the leaves before they start to bolt. Harvest the outer leaves first, leaving the inner leaves to continue growing. You can also pinch off the flower buds to encourage more leaf growth and delay bolting.
Extending the Season with Successive Planting
Instead of planting all your coriander at once, try a succession planting method. This involves planting small batches of seeds every couple of weeks to ensure a continuous supply of fresh coriander throughout the summer.
The Art of Companion Planting
Companion planting can benefit your coriander plants in several ways. Planting coriander alongside other herbs like basil, dill, and parsley can help attract beneficial insects and deter pests. Additionally, these companion plants can create a microclimate that helps protect your coriander from the heat.
Troubleshooting Common Summer Coriander Problems
While following these tips can significantly increase your success rate, it’s important to be aware of potential problems that can arise during the summer.
- Bolting: If your coriander plants start to bolt, pinch off the flower buds as soon as you see them. This will help to delay the process and extend the harvest season.
- Pests: Aphids, whiteflies, and leafhoppers are common pests that can attack coriander plants. Monitor your plants regularly and use insecticidal soap or neem oil to control infestations.
- Diseases: Fungal diseases like powdery mildew and leaf spot can affect coriander plants, especially in humid conditions. Proper spacing and good air circulation can help prevent these diseases.
A Farewell to Summer Coriander
As the summer heat subsides, your coriander plants will eventually start to decline. Don’t be discouraged! You can collect the seeds from your plants and sow them in the fall for a new crop of coriander to enjoy in the cooler months.

Q: How often should I water my coriander plants in the summer?
A: Water your coriander plants deeply every 1-2 days, or more often if the soil dries out quickly. Check the soil moisture with your finger, and water when the top inch of soil feels dry.
Q: What are the best ways to prevent coriander from bolting in the summer?
A: Planting coriander in the cooler months, providing partial shade, and harvesting the leaves regularly can help prevent bolting. You can also pinch off the flower buds as soon as they appear.
Q: What can I do if my coriander plants are attacked by pests?
A: Monitor your plants regularly for signs of pests. Use insecticidal soap or neem oil to control infestations. You can also try introducing beneficial insects like ladybugs to your garden to help control pest populations.
Q: Can I save coriander seeds from my plants?
A: Yes, you can save coriander seeds from your plants. Let the seed heads dry completely on the plant, then harvest and store them in a cool, dry place. You can use these seeds to plant a new crop of coriander in the fall.
