How to Keep Your Cilantro From Bolting: A DIY Guide
Hey there, fellow gardeners! Cilantro, that fragrant herb that adds a zing to everything from tacos to salads, can be a real pain when it decides to bolt – meaning it shoots up a flower stalk and turns bitter. It’s a common problem, especially in warmer weather, but don’t despair! I’ve learned a few tricks over the years to keep my cilantro happy and leafy for longer, and I’m excited to share them with you. Let’s dive in!
Understanding Why Cilantro Bolts
Before we get to the how-to, it’s helpful to understand *why* cilantro bolts in the first place. Think of it as the plant’s survival mechanism. When cilantro experiences stress, like high temperatures, long days, or lack of water, it thinks, “Oh no, I need to reproduce quickly before I die!” So, it puts all its energy into producing seeds, which means flowering and that bitter taste we all dread.
Knowing this helps us target our efforts to reduce those stressors. We’re basically trying to convince our cilantro that it’s in a chill, stress-free environment where it can just focus on growing delicious leaves.
Choosing the Right Cilantro Variety
Not all cilantro is created equal! Some varieties are more bolt-resistant than others. Look for varieties specifically bred for slower bolting. These are often labeled as “slow bolt” or “long standing.” Here are a few I’ve had good luck with:
* Slow Bolt Cilantro: This is a general term, but many seed companies offer a variety specifically labeled as “Slow Bolt.”
* Santo Cilantro: Known for its heat tolerance and delayed bolting.
* Calypso Cilantro: Another reliable option for warmer climates.
Choosing the right variety is a simple step that can make a big difference!
Location, Location, Location: Finding the Perfect Spot
Cilantro prefers partial shade, especially during the hottest part of the day. Direct sunlight can really stress it out and trigger bolting.
* Morning Sun, Afternoon Shade: This is ideal. The morning sun gives it the energy it needs, while the afternoon shade protects it from the scorching heat.
* Filtered Sunlight: If you don’t have a spot with partial shade, try planting it under a taller plant that provides dappled sunlight.
* Avoid South-Facing Walls: These walls radiate heat, which can be detrimental to cilantro.
Planting Cilantro: Getting Started Right
How you plant your cilantro can also affect its bolting tendencies.
* Direct Sowing is Best: Cilantro doesn’t transplant well, so it’s best to sow the seeds directly into the ground or container where you want it to grow.
* Succession Planting: This is key! Plant a small batch of seeds every 2-3 weeks. This way, you’ll have a continuous supply of cilantro, and if one batch bolts, you’ll have another one coming up.
* Spacing: Space the seeds about 2-3 inches apart. Overcrowding can stress the plants.
* Depth: Plant the seeds about 1/4 inch deep.
* Soaking Seeds: Some gardeners recommend soaking cilantro seeds in water for 24 hours before planting to improve germination. I’ve tried it, and it seems to help!
Watering: Keeping Cilantro Hydrated
Consistent watering is crucial for preventing bolting. Cilantro needs moist, but not soggy, soil.
* Water Regularly: Water deeply whenever the top inch of soil feels dry.
* Avoid Overwatering: Soggy soil can lead to root rot, which will also stress the plant.
* Water in the Morning: This gives the leaves time to dry before nightfall, reducing the risk of fungal diseases.
* Mulch: Apply a layer of mulch around the plants to help retain moisture and keep the soil cool.
Soil: Providing the Right Nutrients
Cilantro prefers well-drained soil that is rich in organic matter.
* Amend the Soil: Before planting, amend the soil with compost or other organic matter. This will improve drainage and provide essential nutrients.
* Fertilize Lightly: Cilantro doesn’t need a lot of fertilizer. A light feeding of a balanced fertilizer every few weeks is sufficient. Avoid over-fertilizing, as this can also stress the plant.
* pH Level: Cilantro prefers a slightly acidic to neutral soil pH (around 6.0 to 7.0).
Harvesting: Encouraging Leaf Production
How you harvest your cilantro can also influence its bolting behavior.
* Harvest Regularly: Don’t let the plants get too big. Harvesting regularly encourages them to produce more leaves.
* Cut Outer Leaves: When harvesting, cut the outer leaves first, leaving the inner leaves to continue growing.
* Avoid Cutting the Main Stem: Cutting the main stem can trigger bolting.
* Pinch Off Flower Buds: If you see any flower buds starting to form, pinch them off immediately. This will redirect the plant’s energy back into leaf production.
Cooling Things Down: Temperature Control
Since heat is a major trigger for bolting, anything you can do to keep the plants cool will help.
* Shade Cloth: If you’re growing cilantro in a particularly hot area, consider using shade cloth to provide extra protection from the sun.
* Misting: Misting the plants with water in the morning can help cool them down.
* Container Gardening: If you’re growing cilantro in containers, you can move them to a cooler location during the hottest part of the day.
* Planting Near Taller Plants: As mentioned before, planting cilantro near taller plants can provide shade and help keep the soil cool.
Dealing with Bolted Cilantro: Salvaging What You Can
Even with the best efforts, cilantro can still bolt, especially during a heat wave. But don’t throw it away!
* Harvest the Seeds: Cilantro seeds are coriander! Let the plant flower and go to seed. Once the seeds are dry and brown, you can harvest them and use them as a spice.
* Use the Flowers: Cilantro flowers are also edible and have a mild cilantro flavor. You can use them in salads or as a garnish.
* Compost the Rest: Once the plant has completely bolted and the leaves are very bitter, it’s best to compost it.
Step-by-Step Guide: Putting it All Together
Okay, let’s break down the whole process into a simple, step-by-step guide:
1. Choose Your Variety: Select a slow-bolt cilantro variety like Santo or Calypso.
2. Find the Right Spot: Choose a location with morning sun and afternoon shade, or filtered sunlight.
3. Prepare the Soil: Amend the soil with compost or other organic matter.
4. Sow the Seeds: Direct sow the seeds about 1/4 inch deep and 2-3 inches apart. Consider soaking the seeds for 24 hours beforehand.
5. Water Regularly: Keep the soil consistently moist, but not soggy. Water in the morning.
6. Mulch: Apply a layer of mulch around the plants to retain moisture and keep the soil cool.
7. Fertilize Lightly: Feed the plants with a balanced fertilizer every few weeks.
8. Harvest Regularly: Cut the outer leaves first, avoiding the main stem.
9. Pinch Off Flower Buds: Remove any flower buds as soon as you see them.
10. Succession Plant: Plant a new batch of seeds every 2-3 weeks.
11. Cool it Down: Use shade cloth, mist the plants, or move containers to a cooler location during hot weather.
12. Salvage Bolted Cilantro: Harvest the seeds and flowers.
Troubleshooting: Common Cilantro Problems
Even with the best care, you might encounter some problems. Here are a few common issues and how to address them:
* Yellowing Leaves: This could be a sign of overwatering, underwatering, or nutrient deficiency. Check the soil moisture and adjust your watering accordingly. If the soil is dry, water deeply. If it’s soggy, let it dry out before watering again. You can also try fertilizing with a balanced fertilizer.
* Slow Growth: This could be due to poor soil, lack of sunlight, or cool temperatures. Make sure the soil is well-drained and rich in organic matter. Provide adequate sunlight and protect the plants from frost.
* Pests: Cilantro is generally pest-resistant, but aphids can sometimes be a problem. You can control aphids by spraying the plants with insecticidal soap or neem oil.
* Fungal Diseases: Overwatering and poor air circulation can lead to fungal diseases. Water in the morning to allow

Frequently Asked Questions (FAQ)
What exactly does “bolting” mean, and why is it bad for cilantro?
Bolting is the term used when a plant prematurely flowers and produces seeds. For cilantro, this is undesirable because once the plant bolts, the leaves become bitter and less palatable. The plant’s energy is diverted from leaf production to seed production, resulting in a decline in the quality and quantity of the cilantro leaves. Essentially, bolting signals the end of the cilantro’s useful life as a culinary herb.
How do I know if my cilantro is starting to bolt?
The first sign of bolting is usually the appearance of a central stem that starts to elongate rapidly. You’ll also notice the formation of flower buds at the top of the plant. The leaves may also start to change in appearance, becoming smaller and more feathery. Finally, taste a leaf – if it has a noticeably bitter flavor, it’s a sure sign that bolting has begun. Early detection is key to implementing preventative measures.
What are the best cilantro varieties to grow if I want to avoid bolting?
Certain cilantro varieties are known for their resistance to bolting. ‘Slow Bolt’ and ‘Santo’ are two popular choices that are specifically bred to delay flowering. These varieties are generally more tolerant of heat and other stressors that can trigger bolting. When selecting cilantro seeds, look for varieties that are labeled as “slow bolting” or “bolt resistant.”
How often should I water my cilantro to prevent bolting?
Consistent watering is crucial for preventing bolting. Cilantro prefers consistently moist soil, but not waterlogged. Water deeply whenever the top inch of soil feels dry to the touch. The frequency of watering will depend on your climate, soil type, and the amount of sunlight your cilantro receives. In hot, dry weather, you may need to water daily. Using a soil moisture meter can help you determine the optimal watering schedule.
Can I still use cilantro leaves after the plant has started to bolt?
While the leaves of bolted cilantro are generally considered bitter, some people still use them in cooking, especially in small amounts. The flavor will be significantly different from that of unbolted cilantro, so it’s best to taste the leaves before adding them to your dishes. You can also try chopping the leaves very finely to minimize the bitterness. However, for the best flavor, it’s best to harvest cilantro leaves before the plant bolts.
What is the ideal soil for growing cilantro and preventing bolting?
Cilantro thrives in well-draining soil that is rich in organic matter. Amend your soil with compost or other organic materials before planting to improve drainage and fertility. A slightly acidic to neutral soil pH (around 6.0 to 7.0) is ideal. Avoid heavy clay soils, as they can retain too much moisture and lead to root rot.
Does fertilizing cilantro help prevent bolting?
While cilantro doesn’t require heavy fertilization, providing it with a balanced fertilizer can help promote healthy growth and potentially delay bolting. Use a fertilizer that is specifically formulated for herbs or vegetables, and follow the instructions on the label. Avoid over-fertilizing, as this can actually stress the plant and make it more susceptible to bolting. A slow-release fertilizer is often a good choice for cilantro.
How does temperature affect cilantro bolting, and what can I do about it?
High temperatures are a major trigger for cilantro bolting. When temperatures consistently exceed 75°F (24°C), cilantro is more likely to bolt. To combat this, provide shade during the hottest part of the day, either by planting cilantro in a partially shaded location or by using shade cloth. You can also try growing cilantro indoors under grow lights, where you can control the temperature more easily. Mulching around the base of the plants will also help keep the soil cooler.
Can I harvest cilantro seeds (coriander) after the plant has bolted?
Yes! Once your cilantro plant has bolted and produced seeds, you can harvest them for use as coriander. Allow the seed heads to dry completely on the plant before harvesting. Once dry, you can rub the seed heads between your hands to release the seeds. Store the coriander seeds in an airtight container in a cool, dry place.
Is there anything else I can do to extend the life of my cilantro and prevent bolting?
Regular harvesting is a great way to encourage new growth and delay bolting. Pinch off the top leaves regularly, leaving the lower leaves intact. This will encourage the plant to produce more leaves and postpone flowering. Also, be sure to remove any flower buds as soon as you see them to prevent the plant from diverting energy to seed production. Consistent monitoring and proactive measures are key to keeping your cilantro productive and preventing bolting.
