How to sow flower seeds and precautions for planting flower seeds.

How to sow flower seedsA detailed introduction on how to sow flower seeds and precautions for growing flower seeds in the field of green plants and flowers is as follows:The sowing time should be determined based on the characteristics of the flowers themselves, market demand, local climate conditions, and seedling conditions.Spring sowing flowers. Annual herbaceous flowers grown in the open, most perennial flowers, and woody flowers are suitable for spring sowing. In the northern region, sowing is done from late March to mid-April.Autumn sowing flowers. Flowers that bloom the following year and some woody flowers are suitable for autumn sowing. In the north, sowing is usually done from late August to early September. In the Changchun area, biennial flowers need to be protected from the cold in winter or cultivated as annuals.Sow immediately after collection. Some flower seeds have a high water content, a short lifespan, and easily lose germination ability after losing water, so they should be sown promptly after collection. This includes seeds like calla lilies, Hippeastrum, kaffir lilies, camellias, and begonias.Staged sowing. Some warm-loving flowers with short growing periods can be sown in stages according to need.Year-round sowing. Greenhouse flowers can be sown in the greenhouse throughout the year.Ensuring the normal growth of flowers requires the disinfection of the sowing soil.Sunlight exposure. In the summer, spread the culture soil thinly on a clean cement surface, turn it over 1-2 times a day, and let it be exposed to the intense sun for 15-20 days, which has a certain disinfecting effect.Steam disinfection. This involves using the heat from released steam for disinfection. This method is the most effective and reliable. Maintaining a temperature of 100 degrees Celsius for 10 minutes can achieve the goal of disinfection. A small amount of soil can also be placed in a steamer for 2 hours to achieve the same purpose. A pressure cooker can also be used for disinfection.Chemical disinfection. Common chemicals include formaldehyde, methyl bromide, and chloronitromethane. The method of disinfection is: dilute the chemical with water (see the concentration on the bottle's instructions), spray it on the soil, mix it evenly, then cover the soil with plastic film, remove the film after a few days, scatter the soil, and turn it over multiple times, approximately 1 week for the chemical gas to fully volatilize and leave no residue.Artificially promoting germination before sowing is very important. Germination promotion refers to breaking the seed dormancy by artificial methods to make them germinate. Germination promotion can shorten the seedling emergence period, make seedlings emerge uniformly, and improve the quality of flower seedlings.Soaking and germination promotion. For seeds with a short dormancy period and easy germination, soak in warm water, do not promote germination, and sow directly; while some flower seeds are soaked in warm water at 30-40 degrees Celsius before sowing, then placed in a constant temperature incubator for germination, and sown immediately after the seeds start to germinate.Low-temperature treatment. Some flower seeds need to go through a period of low temperature (0-10 degrees Celsius) treatment to promote maturity and break seed embryo dormancy to germinate.Hormonal treatment. Some flower seeds have the characteristic of epicotyl dormancy, and only the young roots can grow when sown in autumn. They must go through a period of low temperature in winter, and the epicotyl can grow out of the soil in spring. If soaked in a 50-100 mg/L gibberellin solution for 24 hours, the above-ground stem can grow in about 10-15 days.Physical methods. For seeds with hard seed coats that are not easily absorbent, manually abrade or scar the seed coat to promote germination.The above is the full content of how to sow flower seeds and precautions for growing flower seeds, hoping it is helpful to green plant enthusiasts!
