Key facts

Care Guide

Detailed care guide

Coriander is a strongly fragrant herb often used in Southeast Asian and Mexican dishes. Its seeds are also used as a spice, making it a versatile herb.

Watering

It's best to water right away once the soil surface is dry. On average, once every 5 days is appropriate, but it's important to check the soil condition directly depending on pot size and indoor conditions. Overwatering can turn the leaves yellow or mushy, so watch closely.

Light

Bright direct or indirect light suits it well. Insufficient light can cause the stems to grow leggy or the leaves to become pale, so keep it in a bright spot. Very weak light can prevent it from growing healthy.

Humidity

Coriander tolerates average indoor humidity well. It grows fine without extra humidity, but if the indoor air is very dry, the leaf tips may crack or dry out, so be careful.

Temperature

It likes temperatures of 15–25°C best. Growth can suffer if it's too cold or too hot, so keep it somewhere warm but not overly hot, and avoid big temperature swings.

A common first-timer mistake

A common mistake is watering too often before the soil has had a chance to dry. Check with your hand that the soil surface is sufficiently dry before watering.

If you have pets

Coriander is not known to be toxic to pets. That said, eating a large amount of any plant can cause an upset stomach, so if your pet chews on it habitually, move it out of reach.

Seasonal Care

Coriander grows best in spring and fall. During these times, give it plenty of sunlight, and feeding a balanced fertilizer once a month helps it grow healthy. In summer, pay attention to watering in the heat, and in winter make sure the temperature doesn't drop below 15°C. If you manage temperature, sunlight, and watering well, you can keep it lush year-round.

Common Problems and Fixes

If the leaves turn yellow and feel mushy, suspect overwatering. This can happen from watering too often or poor drainage. If the leaf tips turn brown and dry, it's usually due to dryness, strong direct sun, or low humidity. Insufficient light can cause the stems to grow thin and long, so always keep it in a bright spot.

Repotting and Propagation

Planting coriander in well-draining soil helps keep its roots healthy over time. Repot when the soil becomes compacted or loses airflow after long-term growing. Be careful not to damage the roots when repotting, and keep it in slightly shaded conditions rather than strong light for a few days afterward to help it recover. Propagation is generally done from seed.

Who It's Good For

Coriander is easy to care for and grows well without any special equipment or complicated conditions. It's a great fit for anyone trying herbs for the first time, or anyone who wants to grow fresh ingredients for cooking. Since it can grow indoors too, it's easy to start on a balcony or windowsill without much pressure.
