Growing from seed and cuttings
How to grow coriander from seed
Starting coriander from seeds is a satisfying and straightforward process that allows you to enjoy fresh herbs right from your indoor garden. Here's how it works:
1. Soil preparation:
Begin by selecting a well-draining potting mix that is rich in organic matter. Fill pots or seed trays with the soil, leaving about half an inch of space at the top for sowing the seeds. Ensure the containers have drainage holes to prevent waterlogging, which can lead to root rot.
2. Seed sowing:
Coriander seeds are relatively large and easy to handle. Scatter the seeds evenly over the surface of the soil, spacing them about an inch apart. Lightly press the seeds into the soil with your fingers, but avoid burying them too deeply as coriander seeds require light to germinate.
3. Germination conditions:
After sowing the seeds, lightly water the soil to settle them in place. Cover the pots or trays with a transparent lid or plastic wrap to create a greenhouse effect, which helps to maintain moisture levels and promote germination. Place the containers in a warm location with indirect sunlight.
4. Moisture and temperature:
During the germination period, it's crucial to keep the soil consistently moist but not waterlogged. Check the soil regularly and mist it with water as needed to prevent it from drying out. Aim to maintain a temperature range of 18-24°C (64-75°F) for optimal germination. You can use a seedling heat mat to provide gentle warmth if necessary.
5. Thinning seedlings:
As the coriander seedlings emerge and develop their first true leaves, they will need space to grow. Thin out the seedlings by removing the weaker ones, leaving the strongest and healthiest plants spaced about 3-4 inches apart. Thinning helps to prevent overcrowding, promotes better air circulation, and allows the remaining seedlings to thrive.
Growing Coriander from Cutting:
Growing coriander from cuttings offers a convenient and efficient way to propagate this flavorful herb. Follow these steps to successfully grow coriander from cuttings:
1. Select healthy stems:
Choose healthy, non-flowering stems with several sets of leaves. Using clean, sharp scissors or pruning shears, cut the stems just below a leaf node.
2. Rooting method:
Place the cuttings in a glass of water or directly in moist potting soil. Keep them in a warm, bright location, and ensure the soil remains consistently moist until roots develop.
3. Provide humidity:
To promote root development, create a humid environment around the cuttings. You can cover them with a plastic bag or place them in a propagator to maintain high humidity levels.
4. Monitor root growth:
Check the cuttings regularly for signs of root growth. Once roots have developed and are several inches long, the cuttings are ready to be transplanted into individual pots filled with well-draining potting mix.
5. Transplanting:
Gently remove the rooted cuttings from the water or soil and transplant them into their own pots. Ensure that the soil is moist and that the cuttings are planted at the same depth as they were in the water or soil.
6. Provide care:
Place the newly transplanted coriander plants in a bright location with indirect sunlight. Water them regularly to keep the soil evenly moist but not waterlogged. As the plants grow, you can begin harvesting leaves for culinary use.
