How to plant Shandandan flowers?
Light and temperature: Shandandan flower is a wild flower in the north, so it is not so melodramatic. Pay attention to supplement the sunshine after the seeds germinate, and the normal illumination can be maintained for more than 6 hours every day without shading. Pay attention to humidity, not too dry and not too wet. When the weather is fine, put the plants outdoors to breed, and don't accumulate too much water to avoid root rot.
Weeding: As a kind of flower, there will be many small weeds around Shandan, which will compete with plants for nutrients. Weeds should be removed regularly and directly during the growth period. Regularly loosen the soil at seedling stage to ensure that there is enough oxygen in the soil, but be careful when loosening the soil to avoid damaging the roots when the roots are mature and exposed to the surface in the later stage.
Insect pests: Dandan flowers grow rapidly from April to May, and will gradually grow buds. In this process, it is easy to encounter underground pests such as ground tigers and grubs, and it is difficult to control them. Therefore, the bulbs should be disinfected every month during maintenance, and the roots should be watered with disinfectant.
