How to Harvest Cilantro

When is cilantro ready to harvest?

Harvest cilantro when plants are 6 inches tall and carry 4–6 mature leaves per stem. The first harvest can happen 3–4 weeks after germination, well before the plant approaches bolting.

University of Minnesota Extension growth data shows cilantro reaches harvest size fastest in soil between 60°F and 70°F. At those temperatures, germination-to-harvest takes about 3 weeks. In cooler spring soil below 55°F, the timeline stretches to 5–6 weeks. Transplants from a garden center cut this wait to 1–2 weeks because germination already happened.

The correct timing window looks like this:

In my Zone 6b Nashville garden, the window from first harvest to bolt is typically 4–5 weeks in spring. In the Midwest (Zones 4–5), the cooler temperatures extend that window to 6–7 weeks before summer heat arrives. In southern zones (8–10), fall plantings run September through November and give the longest production windows in the US because temperatures rarely spike.

How to cut cilantro without killing the plant

Cut outer stems at the base, leaving the central growing crown and all inner stems intact. This triggers new growth from the center and produces 3–5 subsequent harvests from a single planting.

The cut-and-come-again method is the core skill for productive cilantro harvest. Here is the step-by-step technique:

1. Select the outermost, longest stems — those on the outside edge of the plant.
2. Cut at or near the base, leaving about 1 inch of stem above the soil.
3. Remove no more than one-third of the plant’s total leaf mass at one cutting.
4. Leave all inner stems and the central growing point completely untouched.
5. Check for regrowth in 3–5 days. New stems emerge from the crown within the week.

Harvesting only the tips is the most common mistake. Tip harvest removes just the top inch or two of each stem, which slows new growth and causes the remaining stem to become woody. Cutting at the base removes the full stem and sends a clear signal to the crown to generate new growth from the base.

Morning harvest makes a measurable difference. Cilantro, like most herbs, concentrates its volatile oils overnight. Leaves harvested before 10 AM are more flavorful and stay fresh longer after cutting than leaves taken in the afternoon, after sun exposure has driven off some of the aromatic compounds. The difference is noticeable in raw dishes where cilantro is the primary flavor.

What to do when cilantro starts to bolt

Bolting is triggered by long days and temperatures above 75°F. The first visible sign is a central stem thickening and growing upward faster than surrounding stems — not a flower yet, just a directional change in growth.

Once you see that central stem elongating:

1. Pinch it off immediately with your fingers or scissors. Cut back to the nearest side stem.
2. This delays flower formation by 1–2 weeks, depending on temperature.
3. Repeat every time you see elongating central stems.
4. Harvest remaining outer leaves faster than usual — do not wait for the plant to look ready.

Once flowers open, the entire bolted stem goes bitter within 24–48 hours. The leaves on stems that have flowered are not worth eating. However, the lower stems that have not yet flowered remain flavorful for a few more days. Prioritize harvesting those.

Bolt-resistant varieties extend the production window. ‘Calypso’ and ‘Santo’ are the two most widely available bolt-resistant types in US garden centers. In side-by-side spring tests in Zone 6b, bolt-resistant types ran 10–14 days longer before bolting compared to standard varieties when temperatures climbed into the 80s. That difference is worth choosing them specifically for late-season spring plantings.

Our cilantro growing guide covers variety selection and succession planting strategies that keep fresh cilantro coming even as each individual planting bolts.

How many times can you harvest cilantro?

A single cilantro planting yields 3–5 cuttings over 4–6 weeks before bolting ends production. The exact number depends on your zone, planting timing, and how aggressively you pinch flower buds.

In my Nashville garden (Zone 6b), a spring planting set out in early April gives:

• First harvest: 3 weeks after planting
• Subsequent harvests every 5–7 days until mid-May
• Total: 4–5 harvests, approximately 1–1.5 cups of leaves per cutting per plant

After that, heat above 85°F pushes even bolt-resistant varieties to seed within a week. At that point, I pull the plant and direct-sow a new round — though fall temperatures arrive before that planting has time to produce much. The solution is succession planting 2–3 weeks before the expected last frost and again in early fall.

Succession planting every 2–3 weeks gives you a continuous harvest. Instead of 3–5 cuttings from one planting, you maintain 2–3 plants at different stages and harvest from whichever is at peak. This is what commercial herb growers do and it translates directly to a home garden bed.

How to store fresh-cut cilantro

Store fresh cilantro stems-down in 1 inch of water in a jar or glass in the refrigerator, covered loosely with a plastic bag. This keeps cilantro crisp and flavorful for 1–2 weeks.

The stems-in-water method works better than any other short-term storage approach for fresh-cut cilantro. The stems continue to absorb water, which keeps the leaves hydrated and prevents the rapid wilting that happens when cilantro is stored dry in a drawer.

Step-by-step storage:

1. Rinse stems under cold water after harvest.
2. Trim the cut ends of the stems by 1/4 inch.
3. Place stems in a jar with 1 inch of cold water.
4. Loosely tent with a plastic bag or reusable produce bag.
5. Refrigerate on a middle shelf (avoid the coldest zones near the back or drawer).
6. Change the water every 2–3 days if storing longer than one week.

Counter storage: In a cool kitchen below 70°F, the stems-in-water method also works on the counter for 3–5 days. Above 70°F, counter-stored cilantro wilts within a day. Refrigerator storage is reliable across all US climate zones year-round.

For longer storage, the two best options are drying and freezing. Our how to dry herbs guide covers the air-dry and dehydrator methods that work for cilantro leaves and stems. Our how to freeze fresh herbs guide covers the ice cube tray method that preserves cilantro for cooking use for up to 6 months.

Can you harvest cilantro seeds (coriander)?

Yes. Cilantro seeds are the spice coriander. Let one or two plants bolt and set seed, then collect the dried seed heads before they shatter and drop.

Leaving a bolted plant to go to seed serves three purposes in a US home garden:

1. Free spice: Dried coriander seed from a garden-grown plant is fresher and more aromatic than store-bought. Harvest when seed heads turn brown and the seeds inside have dried to a tan or brown color.
2. Self-sowing: Cilantro is a prolific self-sower. Seed that falls from a bolted plant in May or June often germinates in late August or September when temperatures cool, giving a free fall crop.
3. Seed saving: Collect dried seeds in a paper bag by shaking the seed heads. Store in a sealed glass jar in a cool, dark location. Cilantro seed retains good germination rates for 2–3 years.

To harvest coriander:

1. Let the plant fully bolt and flower.
2. Watch for seed heads to turn from green to tan or light brown — usually 3–4 weeks after flowering.
3. Cut the seed heads before they fully dry on the plant, which causes them to shatter and scatter.
4. Place upside down in a paper bag. Let them dry for another week indoors.
5. Shake the bag to release seeds. Screen or blow off chaff.
6. Store seeds in a sealed jar.

Companion plants that make cilantro harvest easier

Growing cilantro next to the right companions reduces pest pressure and extends productive life. Our cilantro companion plants guide covers this in full, but the key principle: tomatoes, peppers, and spinach grow well next to cilantro without competing for resources, and cilantro’s flowers attract beneficial insects that prey on aphids and whiteflies when the plant is allowed to bolt.

Spinach and cilantro planted together work particularly well in Zones 5–7 because both thrive in cool weather and can share a single row, with cilantro harvested before summer heat forces it to bolt and spinach planted back into that space for a fall crop. Our herb garden guide covers multi-herb bed layouts that maximize kitchen production from limited space.

What to do after the last harvest

Once your cilantro has bolted and flowered, three options:

Option 1: Pull and replant. Pull the spent plant, amend the bed with compost, and direct-sow a fresh round. This works best in spring before peak heat and in fall once temperatures drop below 75°F.

Option 2: Leave it for seed. If you want coriander, leave the plant to fully dry and collect seed as described above. The dried stalks also provide a microhabitat for beneficial insects.

Option 3: Compost. Bolted cilantro breaks down quickly and is an excellent green material for compost. Avoid composting seed heads if you don’t want volunteer cilantro plants — the seed remains viable in compost unless the pile reaches 145°F.
