How to propagate marigolds in the latest way? Marigold propagation methods

Marigold, also known as "yellow hibiscus," is an annual herbaceous plant classified under the Tagetes genus of the Asteraceae family, and is a subdivided variety within the chrysanthemum group. Its flowering period is mainly distributed from June to September, with the entire flowering period occupying a large portion of its growth time. When the flowers bloom, the capitulum is borne singly at the top of the branches, and together with the vivid flower colors, it brings a high ornamental experience. Whether on a home balcony or in parks and landscaping, its elegant and graceful plant form is indispensable.

When marigold blooms, the flower shapes vary considerably, creating a strong visual impact and making it one of the favorite flower varieties in the hearts of flower enthusiasts. Every year during the flowering period, people buy it from the market, but after the flowering period ends, the entire plant will wither away, ending its life span. For flower lovers who love flowers, this inevitably brings a touch of sadness.

In fact, we can choose another way to prolong the life of the marigold, and that is through seed propagation, continuing its life. Around September, the flowers enter the fruit ripening stage. At this time, pick healthy and plump seeds, store them in a dry and ventilated place, and wait until the right time and conditions before sowing and propagating.

1. Why should marigolds be propagated by sowing?

Marigold is an annual flowering plant. What is an annual? It means that after completing a series of growth processes from sowing, growing, flowering, and fruiting, it completes the entire content of its life, then enters a state of withering and death. In other words, it is a plant that completes its life history within one growing season, and this process takes about 8 months.

Because after the fruiting period ends each year, the plant ends its life span; if you want to enjoy the beautiful blooming scenery again the following year, then you must propagate it by sowing. In fact, marigolds can also be propagated by cuttings; but for individuals, cutting propagation has low effectiveness, a low survival rate, and so on.

2. What are the advantages of sowing marigolds?

For annual flowering plants, their growth genes mostly prefer warmth and fear severe cold; they also have strong drought resistance and taboo water accumulation in the soil, so overall care needs to be very meticulous. If other propagation methods are chosen, root rot and difficulty controlling the flowering period are likely to occur.

Therefore, by propagating marigolds through sowing, you can increase the survival rate of propagation and better regulate the flowering period. In addition, for those planting on a large scale, it can also reduce labor and capital input, maximizing planting benefits.

3. When should marigolds be sown to increase the survival rate?

Marigold is native to the warm climate of Mexico, and its long-term growing environment has already formed growth genes that favor warmth and fear cold; in addition, its flowering period is mainly distributed from July to September. If an inappropriate season is chosen for sowing and propagation, it will not only delay the arrival of the flowering period, but also reduce the survival rate of sowing.

Therefore, it is necessary to choose both a season that matches the flowering period and a season with a mild climate. According to the characteristics of the four seasons, choosing spring for sowing and propagation allows it to bloom as scheduled, while the warm climate can promote germination. For the warm south, sowing and propagation can be carried out in February; for the cold north, you need to wait until April before sowing and propagating, to avoid the seedlings being damaged by freezing after they emerge.

Note that spring has frequent rain. If you choose rainy days for sowing and propagation, excessive moisture is likely to occur, leading to bacterial infection and reducing the germination and survival rate of the seeds. Personally, I think it is better to choose warm, sunny weather, and sowing indoors can avoid the changeable climate and prevent accidents.

4. How is marigold sowing carried out?

Marigold sowing and propagation is relatively simple. As long as the soil and seeds are in high-quality condition, a relatively high germination and survival rate can be achieved. Although this is the case in theory, when some flower enthusiasts carry out sowing and propagation, the overall seed survival rate is relatively low. In fact, the reason the seeds cannot sprout is mainly that some details of the sowing work were not done properly. Next, let us discuss how to carry out sowing and propagation.

1. Soil: Soil is the foundation on which seeds depend for survival, and it only needs to meet the conditions of being loose and breathable, free of pests and diseases, and strong in moisture retention. If hard, pest-infested, dry soil is chosen for sowing, the seeds will wither and therefore be unable to germinate. Therefore, it is necessary to prepare sowing soil that is loose and breathable and has strong moisture retention; in addition, looseness and breathability can be achieved by turning or loosening the soil.

① Open-field sowing: Open-field sowing is aimed at large-scale planting sites. According to the physiological characteristics of marigold's shallow root system, the soil depth should be controlled at about 22 cm; too deep or too shallow will hinder seed germination. The climate characteristics of the southern region are different. The southern climate is humid, so choosing a higher terrain for sowing can avoid water accumulation rotting the seeds. The northern climate is dry, so choosing a lower terrain for sowing can achieve better moisture retention and prevent the seeds from drying out and withering.

② Indoor pot sowing: Indoor sowing is aimed at home balcony planting. According to the physiological characteristics of marigold's shallow root system, a medium flower pot depth is sufficient; too deep or too shallow makes water difficult to control. Using the indoor pot sowing method allows artificial control of the soil and dryness and humidity, and the survival rate is relatively higher; however, lacking the nourishment of the natural climate, the rate of sturdy seedlings is lower than that of open-field sowing.

2. Broadcast sowing: Broadcast sowing means evenly scattering marigold seeds on the soil surface. For open-field sowing, lightly covering with a thin layer of soil is sufficient, which helps store moisture and improves the seed survival rate. For indoor pot sowing, there is no need to cover the surface with any covering, and it can be allowed to grow naturally. In addition, whether open-field sowing or indoor pot sowing, the soil must first be thoroughly moistened to prevent the soil from absorbing the seeds' moisture and nutrients in reverse.

5. Care and management after marigold sowing?

1. Light: Marigold likes a growing environment with ample sunlight and greatly taboo growing in a dim location for a long time; however, at the time of sowing, shading care measures need to be taken to promote seed germination and seedling emergence. After the seedlings emerge, manually clear away the obstructing objects and let them receive sufficient soft light, bringing about a vigorous growth state.

2. Moisture: Sowing and propagation place great emphasis on moisture. If the soil becomes slightly dry, it will affect seed germination, so appropriate care methods are needed to maintain soil moisture. For the pot sowing method, when the soil becomes dry, use a fine-nozzle spray bottle to spray, keeping some distance from the soil to avoid soil compaction. For open-field sowing, it can be combined with furrow sowing, which is also a type of direct sowing.

6. When should marigolds be transplanted and planted out?

1. Transplanting: Because marigold seeds are relatively small, the spacing at sowing time is relatively small. If the seedlings are not transplanted several times after emerging, malnutrition and uneven light will occur, thus hindering the growth of the seedlings. Therefore, we wait until the seedlings grow about 4 true leaves before transplanting.

Note: Seedling transplanting greatly taboo water loss. If severe water loss occurs, it will lead to withering and death. Therefore, it is necessary to transplant and plant at the same time, and also spray some water on the seedlings.

2. Planting out: After one transplanting, the seedlings can basically enter the stage of reproductive organ maturity. When they are about to bloom, they can be moved into flower pots, gardens, or flower beds for planting. For households, planting out can be done at the time of transplanting.

In summary, before sowing marigolds, there is no need to treat the seeds, and a relatively high seedling emergence rate can still be achieved. This is the main reason flower enthusiasts love sowing and propagation. In fact, for annual and biennial flowering plants, seed sowing is relatively common. If you want to advance the flowering period, then sow earlier indoors; if you want to delay the flowering period, then sow later indoors, and the flowering period is relatively easy to control. The above is Liangzi's own sowing experience, and I hope flower enthusiasts will offer much guidance.
