How to Grow Cilantro in a Greenhouse? Latest Cultivation Techniques and Methods Tutorial

Cilantro is a commonly used flavoring vegetable in our daily lives, highly favored by consumers. With the development of the planting industry, many vegetables are grown in greenhouses, and growing cilantro in a greenhouse yields higher profits. So how should you grow cilantro in a greenhouse to make it grow better? Let's take a look at greenhouse cilantro cultivation techniques below.

1. Land Preparation and Fertilization

Before planting, the plot must first be prepared and fertilized. Choose loose, fertile sandy loam soil with good drainage for planting. Along with plowing, apply 3000 kg of decomposed manure per mu as base fertilizer, then make beds 2 m wide. If the soil is too dry, water it to keep it moist. After raking the soil fine and leveling it, wait to sow.

2. Selecting Good Seed

For greenhouse cilantro, generally choose varieties that grow quickly and have strong heat tolerance, disease resistance and adaptability. Cilantro can be divided into large-leaf and small-leaf varieties. Although small-leaf varieties have lower yields than large-leaf varieties, they have a rich aroma and strong cold tolerance and adaptability, so small-leaf varieties are generally chosen.

3. Germination Promotion and Sowing

Cilantro likes cool conditions and grows best at a temperature of 15-20 degrees, so the sowing time is generally from August to April. Before sowing, in order to increase the germination rate and achieve uniform emergence, germination promotion treatment is generally carried out first. First, put the seeds into warm water at about 50 degrees, stirring continuously and soaking for 15-20 minutes. After the water temperature drops, continue soaking the seeds for 18-20 hours, then place them in a warm environment to promote germination, moistening them once every 2-3 days. Generally after 10 days, once the seeds show white sprouts, they can be sown. Sowing can be done in drills or by broadcasting, generally sowing 2 kg per mu. After sowing, cover the ground with a layer of rice straw and spray water frequently to keep it moist. Once the seedlings emerge, remove the rice straw promptly and do a good job of thinning and filling in seedlings.

4. Field Management

Cilantro likes cool conditions but fears high temperatures and strong light, so when planting, consider setting up a shade net covering to provide shading and cooling, which benefits cilantro growth and increases yield. During the seedling stage, combine loosening the soil with pulling out weeds in the field to prevent them from taking nutrients. During the growing period, keep the soil in a state that is neither dry nor wet. Water as little as possible during the seedling stage, while during vigorous growth, supply sufficient fertilizer and water to promote rapid growth. Fertilization is mainly with urea and nitrogen-potassium fertilizer, with 10-15 kg applied per mu as a top dressing, which can be done together with watering.

5. Harvesting

Because greenhouse-grown cilantro grows quickly, it should be harvested promptly once it reaches the harvest standard to avoid bolting. Generally, cilantro can be harvested when it grows to 25 cm. The harvest time should be well managed, preferably in the early morning and afternoon, as this helps improve its commercial value.
