Cilantro (Coriandrum sativum), also known as coriander, is a popular herb used in a variety of dishes for its fresh, citrusy flavor. While cilantro is often grown from seeds, you can also propagate it from stem cuttings, even from a grocery store bunch. This method allows you to regrow cilantro and enjoy a continuous supply of fresh leaves. Here’s a step-by-step guide to growing cilantro from stem cuttings.
Step 1: Selecting Healthy Cilantro Stems
When buying cilantro from the grocery store, choose a bunch with fresh, green stems. Look for the following:
- Healthy Stems: Select stems that are firm and free from yellowing or wilting. They should be at least 4-6 inches long.
- Fresh Leaves: The leaves should be bright green, signaling that the plant is still healthy and suitable for propagation.
Step 2: Preparing the Cuttings
- Trim the Stems: Take a sharp, clean pair of scissors or garden shears and trim the bottom of the stems at a 45-degree angle. This increases the surface area for water absorption and encourages root growth.
- Remove the Lower Leaves: Remove any leaves near the bottom inch of the stem. This part will be submerged in water, and having leaves in water may cause them to rot.
Step 3: Rooting the Cilantro Cuttings in Water
- Place in Water: Fill a glass or jar with about an inch of room-temperature water. Place the trimmed cilantro stems in the water, making sure only the bare stems are submerged.
- Change Water Regularly: Place the glass in a bright spot, such as a windowsill, where it can receive indirect sunlight. Change the water every 1-2 days to keep it fresh and prevent bacterial growth.
Step 4: Wait for Roots to Develop
In about 7-10 days, you should start seeing small roots emerging from the base of the cilantro stems. Wait until the roots are at least 1-2 inches long before transplanting. This usually takes around 2-3 weeks.
Step 5: Transplanting the Cilantro Cuttings
Once the roots are well-established, it’s time to transfer your cilantro cuttings into soil.
- Prepare a Pot: Choose a pot that is at least 6-8 inches deep with drainage holes. Cilantro has a long taproot, so deeper pots work better.
- Soil Mix: Use a well-draining potting mix, preferably enriched with organic compost. Cilantro prefers slightly moist, loamy soil with a neutral to slightly acidic pH (6-7).
- Plant the Cuttings: Make a small hole in the soil and gently place the rooted cilantro cutting into the hole. Cover the roots with soil and firm it down gently. Space multiple cuttings about 3-4 inches apart if you’re planting more than one in the same pot.
Step 6: Caring for Your Cilantro Plant
- Light: Cilantro needs about 4-6 hours of sunlight each day. If growing indoors, place the pot in a sunny spot, such as near a south-facing window.
- Watering: Water the cilantro regularly, ensuring the soil stays moist but not waterlogged. Check the soil daily and water when the top inch feels dry.
- Fertilizing: Cilantro doesn’t need heavy fertilizing, but you can feed it with a balanced, water-soluble fertilizer every 3-4 weeks to encourage healthy growth.
Step 7: Harvesting Cilantro
- Time to Harvest: In about 3-4 weeks, your cilantro should be ready for its first harvest. Begin by cutting the outer leaves first, allowing the inner leaves to continue growing.
- Cutting for Continued Growth: When harvesting, snip the stems just above a leaf node (where a leaf meets the stem). This encourages the plant to produce more leaves and prevents it from bolting (flowering too early).
Step 8: Preventing Bolting
Cilantro tends to bolt (produce flowers and seeds) quickly, especially in hot weather. To prevent bolting:
- Keep the Plant Cool: Grow cilantro in cooler indoor conditions or provide shade during the hottest part of the day.
- Harvest Frequently: Regularly harvesting the leaves encourages the plant to focus on producing foliage rather than flowering.
Additional Tips for Success
- Multiple Cuttings: Start several cuttings at once for a fuller, more productive cilantro plant.
- Propagation Cycles: Since cilantro can bolt quickly, it’s a good idea to stagger your propagation by starting new cuttings every few weeks to ensure a continuous supply.
- Pests: Watch for pests like aphids or spider mites, which can affect indoor cilantro plants. If needed, use neem oil or insecticidal soap to treat infestations.
Final Thoughts
Regrowing cilantro from grocery store bunches is a simple and rewarding way to maintain a fresh supply of herbs year-round. With a little patience and care, you can enjoy home-grown cilantro without the need for seeds, ensuring you always have this aromatic herb at your fingertips.
