Tips on growing Coriander indoors

Coriander crop thrives well in temperatures between 17° to 27°C. Coriander is best sown directly in pots rather than growing them in seed trays and then transplanting the sprouts.

You can grow coriander in full sun and well-drained soil with a pH of 6.2 to 6.8. Sow the coriander seeds about half to one inch deep in the soil. Space the seeds at a gap of approximately 6 inches. Press the soil over the seeds and cover with the half-inch layer of fine mulch. Water thoroughly.

Water the plants in dry periods. Be sure to not over-water the plant to avoid root rot. Good soil drainage is essential to ensure healthy root health as coriander has deep taproots. You can choose to buy organic manure at AllThatGrows.

Germination of coriander takes up to 2-3 weeks. Remember to thin young plants to 20 cm apart to allow them to grow to their full size. To extend the coriander harvest, regularly snip soft stems, rotating the plant while you harvest.

How to Care for Coriander

Coriander prefers cool weather similar to spinach and lettuce alike. It can be grown in partial sun as the herb does not demand full soon.

• Avoid transplanting or repotting the germinated seeds and prefer starting from the seeds straight. This will help you avoid bolting.
• The key to growing healthy coriander herb is regular and steady watering. Remember to mulch to keep the soil surface cool.
• For a steady supply, we suggest planting small patches every 2-3 weeks throughout the growing season.

Harvesting Coriander Herb

Coriander can be harvested when the plant has become six inches tall. At this height, the leaves of the herb will be tender and least bitter. The stems tend to be more pungent as compared to the leaves. Cut the gentle stems at soil level.

Harvesting Coriander Seeds

You can also harvest the seeds once coriander plant develops flowers and seed heads. The harvested seed heads should be a brown colour and are available in the seed heads. The seeds can be harvested once they are brown

Dry the harvested seeds before using them in recipes. Store them in an airtight paper bag until they are ready to be planted. You can also sow them immediately for a continuous crop.

How to grow Coriander Leaves (Cilantro) at home

One of the easiest methods of sowing coriander seeds indoors is via sprouting method. Pre-soak the coriander seeds in a shallow dish overnight. Then place these seeds in a plastic sandwich bag and seal it. Place the bag in a spot receiving decent sunlight for a day or two until tiny white sprout appears. Add more water if needed to ensure that the bag retains moisture.

Now that the sprouts have been formed, add some potting soil to the unsealed bag. Plant these seeds in a container filled with fresh soil once the sprouts have expanded in size. Add a thin layer of potting soil on top of these sown seeds. Place the potted seeds in a sunny spot for up to four to five hours. You can move the pot indoors at a spot that receives 4-5 hours of sunlight every day or keeps in shade outdoors.

Growing coriander in Pots

Coriander is a fast-growing annual plant that reaches up to 12 – 22 inches in height. With a little extra care, coriander can grow indoors as well as it would grow outdoors. We recommend you grow coriander herb in a huge planter with rest of the herbs as herbs make great neighbours and encourage healthy growth for each other.

Follow the step by step instructions below for growing coriander indoors.

Pick a spot for your container that exposes the plant to run for at least four to five hours. Prefer exposing the plant to morning sun as it enjoys a lot of light but not too much heat.

Container

Take any container or planter (approx 10 inches) deep enough for the roots. Make sure that you have plenty of drainage holes in the bottom of the container.

Coriander needs extra fertile soil if growing indoors. The root system range is limited and can’t access as much soil for nutrients as in the garden, hence the nutrition content in the soil needs to be higher. Explore rich organic manure at AllThatGrows.

Sowing

Pre-soak the seeds overnight. Space the seeds 3 to 4 inches apart while sowing in the container. You can also sprout the seeds before sowing.

Watering

Water the plants when the soil is dry to the touch. Water thoroughly until the water comes out the drainage holes. Keep the soil moist and not soaked.

Harvest

You can plant new seeds every six weeks to keep a steady supply throughout the season. Follow the same steps for harvesting coriander as recommended under the Harvesting Coriander Herb.

Common problems to avoid while growing Coriander

1. Bolting

Coriander has a tendency to bolt straight into flower i.e instead of growing leaves, the plant jumps straight to the flowering stage. Bolting can occur due to heat, transplantation or insufficient watering.
However, there are some things that you can do to prolong the leaf production phase. Keep the soil moist, and plant the seeds in partial share not too shady as it needs a sufficient amount of sun to grow properly. Coriander is an excellent plant for sowing successionally, so sow regularly every 5-6 weeks.

2. Root Rot

Coriander might suffer from root rot. This situation is developed if the roots of the plant become too wet. Hence well-drained soil with mixed sand is imperative for improved drainage of the plant. Overwatering can also lead to oversaturation of soil and subsequent development of certain leaf diseases. The simple precaution that can avoid this will be watering in the day, avoid watering in the evening and don’t overwater the plants.

Pests & slugs that can affect Coriander

Coriander can have problems with aphids and whitefly, wilt or powdery mildew. Bacterial leaf spot, carrot motley dwarf, armyworm, cutworm, and nematodes can also infect the crop. However, the crop can be mostly saved from pests and viruses with fertilizer. We recommend the usage of organic fertilizer at the growing stage for a healthy yield. You can buy organic fertilizer from AllThatGrows.
