I Seed selection

Dahlia is usually propagated by sowing, and the selection of seeds is particularly important. In order to ensure the quality of sowing, it is best to use artificial pollination to control the seeds

II Sowing method

The planting time of xiaolihua seeds is generally selected in early May. The seeds are sown on demand or in a row in a potted or seedbed, and then gently covered with a layer of 0.3cm soil. Ensure that the temperature is between 15 ° C and 20 ° C, and the humidity and sunshine are controlled at about 70%. Generally, it can germinate in six to eight days, and colonize after growing two leaves

The temperature after colonization needs to be kept between 18 ℃ and 25 ℃. When this leaf grows five to seven, the seedlings can be transplanted. When transplanting, it should be noted that the seedlings must bring the original soil, which can effectively avoid damaging the root tubers of xiaolihua and is conducive to its survival. The distance between transplanted seedlings should be kept between 20 cm and 30 cm

III Precautions

1. Soil. The choice of soil must be fertile and loose, and the drainage must be good. It is best to use sandy soil, and never make the soil sticky

2. Temperature. The survival ability of xiaolihua is still relatively strong. It can grow normally even when the temperature is particularly high in summer, but it is best to control the temperature between 15 ℃ and 20 ℃, so as to be conducive to seed germination

3. Water. After seeds are planted, remember to water the soil thoroughly, and then ensure to water once a day, so as to provide sufficient water for seed germination

4. illumination. Xiaolihua especially likes the mild and cool climate and sufficient sunshine. It is necessary to have a certain illumination time after the seeds are sown, so that the seeds can grow healthily and the germination time will be advanced

Well, that's all for today's sharing. I hope to provide help to friends who want to plant xiaolihua
