How to Propagate Calendula by Sowing? A Detailed Method Guide
Calendula is an annual or overwintering herbaceous plant, often used for flowerbed bedding, with very high ornamental and economic value. Calendula is not difficult to cultivate, and it can self-sow and grows fairly quickly. The editor will now introduce the points to note when sowing calendula by hand; friends who like it can learn about it together.
Calendula
Calendula sowing is often carried out as autumn sowing after mid to late September: sterilize the substrate used for sowing. The best method is to put it in a pot and heat it by stirring, so that any diseases and pests are killed by the heat. In addition, treat the seeds at low temperature before sowing: put the seeds in a 0°C refrigerator for 24 hours, then take them out and sow them directly in the open field. The seedbed should be shaded. They germinate in mid-August. Apply a thin, well-rotted manure water once a week, and they can also bloom in late September.
1. Germination
Soak the seeds in warm hot water (about the same temperature as face-washing water) for 3 to 10 hours, until the seeds absorb water and swell. For very common seeds that germinate easily, this step can be skipped.
2. Sowing
For tiny seeds that are hard to pick up with your hands or other tools, you can moisten one end of a toothpick with water and stick the seeds one by one onto the surface of the substrate, then cover with substrate 1 cm thick. Then place the sowing pot into water, with the water depth at 1/2 to 2/3 of the pot's height, and let the water slowly soak up from below (this method is called the "pot immersion method"), so as to avoid washing the seeds away.
3. Management After Sowing
After autumn sowing, when a cold wave and low temperatures occur, you can wrap the flowerpot with plastic film to help keep it warm and moist. After the seedlings emerge, uncover the film promptly, and let the seedlings receive sunlight before 9:30 every morning, or after 3:30 in the afternoon; otherwise the seedlings will grow very weak and spindly. After most of the seeds have sprouted, appropriate thinning is needed: pull out the diseased and unhealthy seedlings so that the remaining seedlings have a certain amount of space between each other. When most of the seedlings have grown 3 or more leaves, they can be transplanted into pots.

For larger seeds that can be picked up with your hands or other tools, place the seeds directly into the substrate and sow them in spots at a spacing of 3 x 3 cm. After sowing, cover with substrate at a thickness 2 to 3 times that of the seeds. After sowing, you can use a sprayer or a fine-hole watering can to wet the sowing substrate. Later, when the potting soil is slightly dry, water again, still taking care not to water too forcefully, so as to avoid washing the seeds away;

The Benefits and Effects of Calendula, and Calendula's Propagation Methods
Calendula, also called pot marigold or golden marigold, is an annual or overwintering herbaceous plant. Today the editor will share with you the benefits and effects of calendula and calendula's propagation methods.
The benefits and effects of calendula:
1. Ornamental
Calendula has rich flower colors, bright and eye-catching. It is suitable for arranging central squares, flowerbeds, and flower borders, and can also be used as an edging flower for lawns or for potted viewing. Its ornamental role is relatively great.
2. Air purification
Calendula has a strong resistance to sulfur dioxide, and also has a certain resistance to cyanide and hydrogen sulfide. It is an excellent pollution-resistant flower. Whether planted in pots at home or grown in home courtyards, roadside flowerbeds, and other places, it can play a certain role in improving the air.
3. Edible
Calendula is rich in a variety of vitamins, especially vitamin A and vitamin C, and almost all its parts can be eaten.
4. Medicinal
Calendula's flowers and leaves have anti-inflammatory and antibacterial effects, especially with better effects against Staphylococcus and Streptococcus. Its roots contain bitter principles, and its seeds contain glycerides, ceryl alcohol and alkaloids, giving it a certain medicinal value.
Calendula's propagation methods:
1. Sowing propagation is a very common propagation method. It is generally carried out as autumn sowing in mid to late September, but before sowing, the seeds need to be sterilized first. The best way to sterilize them is to put the seeds in a pot and stir-fry and heat them, so that the diseases and pests inside the seeds are all killed by the heat. Use warm hot water to soak the seeds for about 3 to 10 hours, until the seeds absorb water and swell, and then such seeds can germinate very easily. Place the seeds one by one on the surface, then put the sowing flowerpot into water, and at the same time the water depth should not be too deep.
2. Cutting propagation is also a commonly used propagation method. Generally, when selecting cuttings, it is done together with pinching. The thicker top parts that are cut off and have no pests or diseases are used as cuttings. When cutting, the temperature should not be too low, otherwise the cuttings will not easily take root and their growth will become even slower; but if the temperature is too high, their cut ends may rot. Therefore, when cutting, the temperature should not be too low, and at the same time not too high.
