Growing cilantro indoors requires a pot with good drainage and a planting solution composed of sand and potting soil. An unglazed pot works best. Use a fertilizer composition of 20-20-20.
The plant should receive four to five hours of full sun per day. A growing light can help provide the necessary light exposure.
It is more important to water the soil completely than water the surface frequently. Water should exit the pot's drainage hole to ensure that the plant's root system is receiving adequate moisture.
When growing indoors, cilantro plants tend to become spindly. To encourage growth, pinch the plant's tips off. This makes the plant thicker.
