Discover expert-backed tips to grow cilantro (coriander) in hot weather. Learn succession planting, heat management, and harvest tricks so you never run out of fresh, flavorful leaves this summer.
Why Cilantro Struggles in Summer — And How to Beat It
Cilantro (Coriandrum sativum) is a cool-season herb beloved for its citrusy, peppery flavor. But as soon as summer heat hits, many gardeners watch in frustration as it bolts to seed in just a few weeks.
This summer, you don’t have to settle for sad, spindly plants. With a few pro techniques, you can enjoy a lush supply of cilantro for tacos, salads, salsas, and garnishes—from June through September.
Greenmuse Hot Tip: The trick isn’t fighting summer—it’s working with it.
Tip 1: Give Cilantro a Break from Scorching Sun
Full sun might sound ideal for herbs, but cilantro prefers cool roots and gentle light once temperatures rise.
Best practice:
- Morning sun, afternoon shade → Protects delicate leaves from sun scorch.
- Plant alongside taller companions like tomatoes, peppers, or okra to create living shade.
- Use a shade cloth (30–40%) on raised beds during heat waves.

Tip 2: Keep Soil Cool & Consistently Moist
Heat and dryness signal cilantro to flower early.
Action plan:
- Mulch with straw, shredded leaves, or compost to lock in moisture and keep soil 5–10°F cooler.
- Water deeply 2–3 times a week, focusing on root zones (not leaves) to prevent fungal disease.
- Avoid waterlogging—well-drained soil is still essential.
Trending Tip: Pair with clay ollas or buried terracotta pots for slow, steady hydration. This ancient method is making a comeback among sustainable gardeners on TikTok.
Tip 3: Succession Plant Every 2–3 Weeks
One sowing won’t last all summer. To keep a steady supply:
- Sow a new row every 2–3 weeks in different garden spots.
- Mix fast-maturing varieties like ‘Calypso’ with slow-bolting types like ‘Caribe’ for staggered harvests.
- If you love container gardening, dedicate one pot to each planting wave for easy rotation.
Pro hack: Use a long-handled seeder to save your back—makes planting fast, precise, and Instagram Reel–worthy.
Tip 4: Harvest Smart for Maximum Regrowth
Instead of pulling whole plants, cut outer leaves first and let inner growth continue.
- Harvest in the cool morning for peak flavor.
- Use sharp scissors to avoid crushing stems.
- Cilantro regrows quickly—think of it as a “cut-and-come-again” crop.
Save the seeds! When plants bolt, collect coriander seeds for cooking or replanting in fall.
Tip 5：Make Cilantro Part of Your Summer Meal Flow
Link your harvest to your kitchen habits:
- Taco Tuesdays → harvest fresh cilantro for salsa.
- Summer salads → toss in chopped cilantro for a zesty twist.
- Infused water → try cucumber-cilantro for a cooling drink.
