1. Cauliflower planting time: There are many varieties of cauliflower, which correspond to the climate of each season. Very early-maturing and early-maturing varieties are resistant to heat and high temperatures, and are suitable for planting in summer. The time is from June to September. Mid-maturing and late-maturing varieties are not resistant to high temperatures, but are cold-resistant and are suitable for planting in spring and winter. The planting time is from November to February of the following year. In addition, the planting time is slightly different in different regions, so the planting time is determined by the variety and local climate. Right, cover the seedlings with plastic film after transplanting, which can prevent freezing and improve the survival rate of cauliflower seedlings.

2. How to grow cauliflower:

(1) Sowing: Cauliflower seeds can be sown directly without any treatment, but their seeds are small and need to be sown by broadcasting. The seeds must be planted evenly and covered with a layer of organic soil. After watering, germination will take place in about 3-4 days.

(2) Light: Cauliflower does not have strict requirements for light and prefers an environment with sufficient light. With sufficient light, the plants will grow strong, the curds are compact and bright green in color. If the light is insufficient, the plants will grow poorly and the curds will be small. The color is dull.

(3) Temperature: Cauliflower likes a warm environment, and the suitable growth temperature is 20-25 degrees. It is more difficult to form flower bulbs at temperatures above 25 degrees. Low temperatures below 0 degrees will freeze the plants.

(4) Soil: Cauliflower has strong adaptability and does not have high soil requirements. It is best to plant it in sandy loam soil with deep soil and rich in organic matter. The soil pH value is between 5.5-6.5.

(5) Watering: Cauliflower has a large demand for water, so it must always maintain sufficient water. Lack of water will affect the formation of the flower bulb or the quality of the flower bulb will be poor.

(6) Cultivating and weeding: Pay attention to weed removal during the growth period of cauliflower, and it can be combined with weeding and soil loosening 1-2 times.

(7) Fertilization: When planting cauliflower, reasonable fertilization is indispensable. You can try seedling fertilizer one week after planting, and apply compound fertilizer after three weeks to allow the roots to grow quickly.

(8) Pests and diseases: Cauliflower has broad and fat leaves and juicy meat, which makes it susceptible to pests, especially cabbage caterpillars, budworms, etc., so it must be sprayed regularly to prevent and control pests.
