Cilantro, also called coriander in some regions, is one of the most versatile herbs in the kitchen. Its refreshing, citrus-like flavor adds a distinct note to salsas, curries, soups, and marinades. While it is often thought of as a seasonal herb, you can easily regrow cilantro indoors, ensuring a constant supply right where you cook. With just a few steps, cilantro can thrive either in soil-filled containers or even in a simple glass of water, making it one of the easiest herbs to keep replenished.

Why Regrow Cilantro Indoors?

Indoor herb gardening has become a popular trend for those who want fresh ingredients at arm’s reach. Cilantro, however, can be a little tricky outdoors because it has a relatively short life cycle and bolts quickly in warm conditions. By regrowing it indoors, you can control light, water, and temperature, keeping the plant productive for longer.

Moreover, regrowing cilantro from cuttings or stems means less waste. Instead of throwing out leftover stems, you can place them in water or soil and enjoy another cycle of growth.

Regrowing Cilantro in Water

One of the simplest ways to regrow cilantro is by using water. This method requires no soil, making it neat, convenient, and perfect for small kitchens.

Steps to regrow cilantro in water:

  1. Choose fresh stems: Select healthy cilantro stems with at least 3–4 inches in length. The stems should still be green and not wilted.

  2. Trim the bottom: Cut the ends at an angle to expose fresh tissue, which helps the stems absorb water.

  3. Prepare a container: Place the stems in a clear glass or jar filled with clean, room-temperature water. Only submerge the bottom 1–2 inches of the stems.

  4. Place in light: Put the glass near a sunny windowsill or under grow lights. Cilantro needs at least 5–6 hours of light per day.

  5. Change the water: Refresh the water every two days to prevent bacteria and to ensure the stems stay healthy.

  6. Wait for roots: In about a week, small roots will begin to emerge. Once roots grow to 1–2 inches, the stems can either remain in water or be transferred to soil for stronger growth.

While cilantro can survive in water, it generally grows more robustly when transplanted to soil after rooting. However, even if kept in water, you can harvest the leaves as they appear for a quick garnish.

Regrowing Cilantro in Soil

For a more productive and longer-lasting supply, regrowing cilantro in soil is the best method. Soil provides nutrients that water alone cannot, allowing the plant to flourish and produce more leaves.

Steps to regrow cilantro in soil:

  1. Prepare a pot: Choose a container at least 8–10 inches deep with drainage holes. Cilantro has long taproots and needs space to grow downward.

  2. Use the right soil: Fill the pot with well-draining potting mix. A mix enriched with compost or organic fertilizer will encourage lush growth.

  3. Plant rooted stems or seeds: You can transfer rooted stems from the water method into the soil, or simply sow cilantro seeds directly. If planting stems, bury them about 2 inches deep.

  4. Provide sunlight: Place the container in a south-facing window where it receives direct sunlight. If natural light is limited, supplement with grow lights for 12–14 hours daily.

  5. Water consistently: Cilantro prefers slightly moist soil. Water when the top inch feels dry, but avoid waterlogging as it can damage the roots.

  6. Harvest regularly: Once plants are 4–6 inches tall, begin cutting the outer leaves. Regular harvesting encourages more leaf production and delays flowering.

Maintaining Your Indoor Cilantro

Regardless of whether you grow cilantro in water or soil, there are a few tips to keep it thriving indoors:

  • Cool conditions: Cilantro does best in temperatures between 60–75°F (15–24°C). Avoid keeping it near stoves or heaters.

  • Succession planting: Cilantro has a short cycle before it bolts to seed. Planting new stems or seeds every two weeks ensures a continuous supply.

  • Air circulation: Good airflow prevents fungal issues and keeps leaves fresh. A small fan nearby can help in closed indoor spaces.

  • Fertilizer boost: If growing in soil, feed with a diluted liquid fertilizer every 2–3 weeks for added nutrients.

Harvesting and Using Fresh Cilantro

Cilantro leaves can be harvested continuously as long as you don’t remove more than one-third of the plant at a time. Snip leaves close to the base, starting with the outer ones. The younger, inner leaves will continue to grow.

Freshly harvested cilantro elevates meals instantly. Use it as a topping for tacos and burritos, mix it into salads, stir it into soups at the last moment, or blend it into chutneys and pestos. Since cilantro loses much of its flavor shortly after cutting, growing it indoors ensures that you can enjoy its vibrant taste at its freshest.

Final Thoughts

Regrowing cilantro indoors, whether in water or soil, is an easy and rewarding way to keep this flavorful herb on hand. The water method is simple, space-saving, and beginner-friendly, while the soil method offers stronger, longer-lasting plants. With just a little effort, you can enjoy continuous harvests and never have to rely solely on store-bought cilantro again.

An indoor cilantro garden not only saves money but also adds freshness to your cooking, giving you organic, home-grown flavor any time you need it.
