When to Sow Marigolds
This article introduces when to sow marigold seeds and the experience of green plant maintenance regarding marigold seed planting methods and timing. Next, the editor will provide an introduction.
Marigolds, commonly known as marigold flowers, are one of the most common herbaceous flowers in early spring gardens and cities. They belong to the Compositae family of biennial herbaceous plants, with flowering colors of yellow or orange yellow. The blooming period is from April to September, and the fruiting period is from June to October. They prefer a mild and cool climate and have a certain degree of cold resistance. Here is a brief introduction to marigolds for you today.

I. Marigold Planting Time:
The growth temperature of marigolds is between 7-20°C, making them suitable for sowing in spring and autumn. Spring sowing is from February to May, and autumn sowing is from August to October. In the south, sowing is possible when the temperature is above 10 degrees Celsius in winter. Seedlings can tolerate temperatures as low as -9°C, while adult plants prefer 0°C. If the temperature is too low, a protective film is needed after planting to maintain warmth. Marigolds prefer充足 sunlight and slightly shaded areas and have some drought resistance.
II. Marigold Planting Methods:
1. Sowing Amount: The sowing amount of marigold seeds is 4-6 kg per mu. Different sowing methods may result in different sowing amounts.
2. Land Preparation: Marigolds prefer loose, well-drained, and fertile soil. Before sowing, it is necessary to carefully prepare the land, raking to a depth of 20-25 cm, breaking up the surface soil, and pressing it flat to make the field level. At the same time, sufficient base fertilizer should be applied, with 10-15 kg of nitrogen fertilizer and 5-10 kg of phosphate fertilizer per mu, keeping the soil moist.

3. Seed Treatment: Choose high-quality marigold seeds and晒种 before sowing, with a thickness of 1 cm, for 4-6 hours to remove pathogenic bacteria and improve germination rates. Then soak the seeds in warm water for 3-10 hours until they absorb water and swell. Sprinkle the seeds on the soil surface, cover them with a thin layer of fine soil, and water appropriately to keep the soil moist. Seedlings usually emerge within 7-12 days after sowing. When the seedlings have 2-3 true leaves, they can be thinned and transplanted. Density should be controlled to avoid affecting later growth and flowering quality.

4. Management: When the marigold seedlings are about 30 cm tall, remove weeds and loosen the soil. Water promptly when needed, with the amount of irrigation depending on soil moisture. During the budding period, fertilization should be combined with irrigation. Marigolds are prone to diseases and pests during the growing season and hot weather, so it is important to use pesticides promptly to avoid affecting the flowering period.
III. Main Uses of Marigolds:
Marigolds are widely cultivated in gardens, mainly used for potted plants and flower bed decorations due to their high ornamental value. They can also be eaten for their cooling and fire-reducing properties and have high medicinal value, making them a versatile flower variety.
