Attention should be paid to the treatment of seeds before sowing

Flowers had better be treated before sowing, otherwise it is easy to cause the seeds not to sprout. But different flower seeds are treated differently. The editor will introduce you how to deal with flower seeds so that they can germinate smoothly.

Different seed treatment methods should be adopted for the seeds of different flowers: the seed soaking method can be used for the seeds that are easy to germinate. If a bunch of red seeds are soaked in 40 ℃ of warm water for one day and night, rinse thoroughly and then sow. Hard seeds such as asparagus, peony, Jiulixiang, Bairihong, Daphne, etc., should be soaked in warm water of 40 ℃ for about 48 hours, and then sowed in potted soil. After 20 to 30 days, they can sprout and grow. For the seeds of Pearl Plum and Bauhinia which have a short dormant period and are easy to germinate, the seeds can be sowed directly after soaking in warm water of 40 ℃ to 60 ℃ for 24 to 48 hours.

The seeds of some flowers, such as cloves, wintersweet and some herbaceous flowers sown in autumn, need to be treated at low temperature (0 ℃ to 10 ℃) for a certain period of time to promote post-ripening and break the dormancy of seed embryos to germinate. The specific method is to mix the seeds with sand with 60% humidity, then put them in a plastic bag, tie the mouth of the bag tightly, place it in a flowerpot, and then bury the pot in an open field 40 to 60 centimeters deep; you can also put the seeds in a refrigerator of 3 ℃ to 5 ℃ for 60 to 90 days and sow them in spring. You can also choose to sow seeds in autumn so that the seeds can be naturally frozen outside in winter and germinated and unearthed the following spring.

The seeds of some flowers, such as tassel and peony, have the characteristics of double dormancy of radicle and Hypocotyl, that is, the radicle needs to go through a high temperature stage of 25 ℃ to 32 ℃ for 1 to 2 months or more. For this kind of seed, it must be mixed with wet sand before sowing, after a period of high temperature, and then transferred to low temperature, after high temperature treatment, spring sowing can germinate quickly.
