How to Plant Coriander Seeds
How to Plant Herbs Indoors
Start by filling your jar or pot with a high-quality indoor herb garden soil mix. Lightly water the soil until it becomes evenly moist. Sow your herb seeds about 1.5 cm (½ inch) deep, spacing them out to encourage strong growth. Cover the seeds with a thin layer of compost and place the container on a warm, bright windowsill. Most culinary herbs can be planted indoors all year round.
Where to Place Your Indoor Herb Garden
For healthy, flavourful herbs, position your indoor herb garden in a warm, sunny window with plenty of natural light. Avoid drafty areas or windows that become cold at night.
As your herbs grow, rotate the containers regularly so the plants won’t lean toward the light. If you're using grow lights, keep them on for about 14 hours per day. Place the lights just a few inches above the seedlings and raise them as your plants grow taller.
If herbs appear leggy, lower the lights slightly. If leaves develop pale or white spots, the lights are too close. Thin out crowded seedlings using scissors to promote healthy airflow and growth.
When to Water Indoor Herbs
Water your indoor herb garden once a day or whenever the topsoil feels dry. The soil should stay moist but never waterlogged, as this can cause root rot. If plants begin to overcrowd the pot, trim them back with clean scissors to keep your herbs healthy and productive.
How to Harvest Herbs Indoors (Coriander Example)
Indoor cilantro typically offers a fresh harvest about once a week. Regular harvesting encourages bushier growth and helps prevent the plant from bolting. If you're not ready to cook with the fresh cuttings, you can freeze them for later use.
When harvesting, use clean, sharp scissors and cut the stems just above a set of leaves. Always leave a few leaves on the plant so it can continue to produce new growth.
Freshly harvested coriander is perfect for enhancing Mexican, Thai, and other Asian dishes—and regular picking keeps your indoor herb garden thriving for longer.
