How to grow Coriander Seeds
Coriander is a versatile herb that can be grown in the garden, in containers, or started indoors in a greenhouse or on a warm windowsill.
Sowing Coriander Seeds
Sow coriander seeds about 1 cm deep and 15–20 cm apart to allow enough room for the plants to grow. Lightly cover the seeds with soil and gently press down to secure them in place.
Germination & Watering
Water the seeds thoroughly and keep the soil consistently moist but not waterlogged, especially during the germination period, which typically takes 7–21 days at temperatures between 15°C and 25°C.
Location & Soil
Select a sunny location in your garden or a suitable container with a minimum depth of 20 cm. Prepare the soil by loosening it to a depth of about 30 cm and adding organic matter like compost to improve fertility and drainage.
Ensure the soil pH is between 6.2 and 6.8 for optimal growth. Alternatively, sow coriander seeds indoors in a greenhouse or on a warm windowsill, and do not move plants outside until summer.
Seedling Care
Once the seedlings have grown to about 5–7 cm tall and have at least two true leaves, thin them to maintain the recommended spacing. This helps ensure each plant has sufficient nutrients, light, and air circulation.
Regularly water the plants to keep the soil evenly moist, and provide at least 4–6 hours of sunlight daily.
Harvesting
Harvest coriander leaves when the plants are about 10–15 cm tall, usually around 3–4 weeks after planting. Coriander plants are considered mature in approximately 60–90 days.
Regularly harvesting the outer leaves encourages the plant to produce more foliage. If you want to harvest seeds, allow the plants to flower and form seed heads. When the seed heads turn brown and dry, collect them, dry the seeds thoroughly, and store them in an airtight container for future planting.
