Marigold Planting Methods and Precautions Explained in Detail
The suitable growing temperature for marigolds is 15-25°C, the suitable temperature during the flowering period is 18-20°C, the relative air humidity of the growing environment is required to be 60-70%, and the winter temperature should not be lower than 5°C. In summer, when the high temperature is above 30°C, the plants grow leggy, the stems and leaves become loose, and there is little flowering. Below 10°C, growth slows down. Marigolds are light-loving plants, and sufficient sunlight is very beneficial to their growth, making the plants short and sturdy with brilliantly colored flowers. Below, the editor brings you the planting methods and precautions for marigolds. Let's take a look at the details.
Marigold planting methods:
Temperature and light
Marigolds like a warm, humid environment with sufficient light. The suitable growing temperature is 20-30°C. In summer, the temperature should not be higher than 30°C, and the overwintering temperature in winter should be above 5°C. It is necessary to ensure that marigolds receive sufficient sunlight so that they bloom brilliantly. With insufficient light, the plants tend to grow leggy, which is not conducive to flowering.
Soil
Marigolds are not strict about soil requirements, and loose sandy soil with good aeration and drainage is best.
Watering and fertilizing
During the growing period, marigolds should be watered frequently, but the amount of water each time should not be too large; water when the soil is dry and let it dry out between waterings. When watering, the method should be changed according to the seasons: water in the morning in summer and autumn, and at noon in winter and spring.
Marigolds should be fertilized moderately. When planting, a set amount of base fertilizer should be applied. During the growing period, apply liquid fertilizer once a month. Do not apply too much nitrogen fertilizer, so as to avoid leggy growth and failure to bloom.
Precautions for growing marigolds:
Propagation
Marigolds are mostly propagated by seeds. They can be sown in spring and transplanted after seedling raising. They can also be propagated by cuttings in summer.
Pruning
After transplanting, marigolds can be pinched to promote more branching and more flowering.
After marigolds bloom, the faded flowers should be cut off in time, and overly dense branches and leaves should be pruned, which can stimulate new branches to promote more flowering. It can also promote marigolds to grow a large number of aerial roots. When the aerial roots grow larger and thicker, the marigold can be cut off at the stem and replanted. Heavy pruning and layering can also be done, but heavy pruning easily affects plant growth, leading to poor growth of long branches and leaves and poor flowering.
Pest and disease control
Marigolds have relatively few pests and diseases. The more common ones are leaf spot, damping-off, powdery mildew, aphids, and leaf miners. Chemical treatments can be used for control.
How to plant marigolds: marigold planting methods and precautions
Marigold - just from the name, you can tell it is a flowering plant that is very popular among people, because its name is very auspicious. Marigolds not only have a good name, but their flowers are also large and brightly colored, and their flowering period is also very long. They are often grown in parks or community flower beds. Below, let's learn about marigold growing techniques with the editor!
How to plant marigolds
1. The marigold seeds selected must not be bad, rotten, etc., and then they are planted in spring. Note that only one seed is needed per flower pot.
2. Prepare suitable sowing soil: water the potted soil thoroughly the night before, and sow directly the next day.
3. Fertilize and water marigolds: apply fertilizer and water together once every 3 days (no fertilization is needed before germination).

Can marigolds be grown at home?
Marigolds can of course be grown at home. Marigolds have large and brilliantly colored flowers and are often cultivated for ornamental purposes, so growing them at home is naturally also a good choice. Growing marigolds at home is not difficult in terms of management either. Keeping a pot of marigolds at home can regulate the home environment, create a gentle household atmosphere, and make the whole home full of harmony. When in bloom, the golden flowers of the marigold set off the green leaves, creating a very harmonious combination that can reflect a certain poetic and picturesque quality. Growing marigolds at home can actually improve home feng shui and make the family harmonious.
Although marigolds have a strange smell, placing them in the home can drive away flies and mosquitoes, making them a natural mosquito coil. Drying marigold flowers and using them to make tea can have certain health-care and medical effects. When the marigold flowers fade, it is exactly the right time to pick the flowers, dry them, and use them for making tea, so it can be said to serve two purposes at once.
As mentioned above, marigolds are a kind of Asteraceae plant that is especially easy to grow, with strong vitality and especially good adaptability. Generally, they do not need elaborate care, but because marigolds have a rather strange smell, some flower lovers do not particularly like them!
How to plant marigolds: marigold planting methods
Marigolds not only have excellent ornamental value, but also have high economic value. The food coloring E161b is extracted from marigolds. So how are marigolds planted? Next, let's look at the planting methods for marigolds.
I. How to plant marigolds
Marigolds are usually propagated by seeds. They are generally divided into two sowing seasons, spring sowing and autumn sowing, and the suitable sowing temperature is 18-22 degrees. Outdoor sowing is generally in spring. Marigolds are not strict about soil requirements, and sufficient base fertilizer should be applied before large-scale planting. First deep-plow and finely harrow the seedbed, level it, and water it thoroughly. After the water seeps down, spread a thin layer of fine soil over the seedbed, then evenly sow the seeds in rows on the fine soil. After sowing, cover with a layer of fine soil, with a thickness of about one time the diameter of the seeds. At night, warmth-preserving measures should also be taken. Cover with cattail mats or plastic film. Before emergence, generally do not water. When the seedlings have 2-3 leaves, divide the plants and plant them separately in nutrient pots or seedbeds. After transplanting, the uniformity of the seedlings is better.
Because marigold plants are not very tall, they are very suitable for home potting. Home potting requires fewer seedlings, and generally does not require seedling raising before sowing. They can be sown directly in the flower pot. Firm the soil in the flower pot, water it thoroughly, and after the water penetrates, scatter the seeds on top, also covering with a thin layer of soil. If the temperature is not high, keep them warm as well. During the seedling stage, do not divide them too much, and no fertilization is needed.
II. Marigold planting methods
1. Plot selection: For marigold cultivation, choose plots without waterlogging, with convenient irrigation and drainage, facing the sun, and with relatively high organic matter content. Avoid sandy land and plots where herbicides with long residual effects have been applied. Combined with land preparation, apply 30 cubic meters of organic fertilizer, 300 kg of diammonium phosphate, and 100 kg of potassium fertilizer per hectare for marigolds. Autumn land preparation and ridging are advocated.
2. Transplanting time: Marigold seedlings generally begin to be transplanted on May 20 each year, and transplanting ends before May 28. Transplanting is best when the seedlings are 12-18 cm tall and have 3-4 pairs of leaves. At night, warmth-preserving measures should also be taken. Cover with cattail mats or plastic film. Before emergence, generally do not water. When the seedlings have 2-3 leaves, divide the plants and plant them separately in nutrient pots or seedbeds. After transplanting, the uniformity of the seedlings is better. That is all for seed propagation in marigold cultivation. Water thoroughly the day before transplanting marigolds, which is beneficial for lifting the seedlings. Use 65-70 cm ridges, make holes, and plant with water. To prevent underground pests, an appropriate amount of phoxim can be added to the water. The plant spacing is 35-40 cm, and 2600-3000 plants are kept per mu.
3. Seed propagation: Marigolds are usually propagated by seeds. They are generally divided into two sowing seasons, spring sowing and autumn sowing, and the suitable sowing temperature is 18-22 degrees. Outdoor sowing is generally in spring. Marigolds are not strict about soil requirements, and sufficient base fertilizer should be applied before large-scale planting.
