Planting

Cilantro

Planting Time Cilantro is finicky and likes the air cool but the soil warm. Plant it in early spring or fall. Once the weather gets hotter than a match head, it will bolt to seed and turn bitter. Plant a new batch every few weeks to keep the fresh leaves coming.

Depth & Spacing Sow seeds one-half inch deep and space them six to eight inches apart. Give the plants room for good airflow to keep them from getting too humid.

Soil & Fertilization Cilantro likes loose, well-drained soil. Mix in plenty of compost. It is not a heavy feeder, so avoid too much nitrogen.

Watering Needs Water consistently to keep the soil moist but not soggy. Watering is key to keeping the plant from bolting.

Sunlight Requirements Cilantro prefers full sun in cool weather. In warm climates, plant it where it will get morning sun and afternoon shade.

Harvesting Harvest the outer leaves when the plant is about six inches tall. Do not cut more than a third of the plant at a time. If it starts to produce a flower stalk, cut it off to encourage more leaf growth. If you let it flower, you can harvest the seeds (coriander).

Troubleshooting The main problem is bolting when the weather gets hot. Use shade cloth or plant under taller crops to keep it cool. Watch for aphids.

Captain Greenhouse Tip Cilantro grows great in a greenhouse if you keep it cool. Put it next to the vents or use a fan for strong airflow. Plant small batches continually for a steady supply.
