How to Grow Cilantro Well? A Detailed Guide to Planting Methods and Techniques

First break open and soak the cilantro seeds. After the shells soften, evenly broadcast them over a plot with loose soil, rich in organic matter, and convenient drainage and irrigation, then cover with a layer of fine soil. Then wait for them to sprout. During the growing period, keep the soil moist and water once every 5-7 days. Once the cilantro grows leaves, water it and apply some organic fertilizer. Finally, do a good job of pest and disease control.

Common cilantro pests and diseases and their control methods are as follows:

1. Cilantro sclerotinia rot

This disease easily occurs throughout the entire growing period, so throughout the growing period ventilation should be strengthened to reduce humidity and lessen the occurrence of the disease. In addition, if the plot has been affected by this disease, crop rotation should be implemented, or the soil should be disinfected.

2. Cilantro leaf blight and leaf spot

These two diseases spread rapidly and cause relatively serious damage. They mainly harm the leaves. After the leaves are infected, they turn yellowish-brown; when humidity is high, the diseased parts rot, and in severe cases the infection spreads downward along the leaf veins to the tender stems and then to the heart leaves, causing serious yield reduction. Therefore, growers should pay attention to prevention, generally using seed disinfection as the main preventive measure. The method is to soak the seeds in a 500-fold solution of “Captan” or “Carbendazim” for 10-15min, rinse them clean, and then sow. The next step is to strengthen management. In the early stage after closing the greenhouse, when humidity is relatively high, attention should be paid to ventilation and dehumidification. If disease is found, spray promptly for control. Use a 600-800-fold solution of Carbendazim, a 600-fold solution of Mancozeb, an 800-1000-fold solution of 70% Thiophanate-methyl, or a 500-fold solution of Chlorothalonil. Mixing two or more of these for use gives better results.

3. Cilantro root rot

This disease mostly occurs in low-lying, humid plots. After the cilantro root system is affected, the main root becomes yellowish-brown or brown, soft-rotted, with no or almost no fibrous roots. When pulled by hand, the plant's root system breaks off. Above ground, the plant appears short and small, with yellow, withered leaves, losing its marketability. Therefore, we should try as much as possible to avoid planting in low-lying areas.

Cilantro diseases should still be mainly prevented, with preventive work done in advance to reduce losses. If disease occurs, treat it promptly to control the condition and prevent large-scale spread.
