1、 Planting method
When planting dahlia, it is suggested to promote the bud of root tuber first, so that its bud point can be clearly displayed. There are two situations after germination. One is that new buds can be used for cutting directly, and the original seed ball can be replanted, so that reproduction can be carried out. In addition, larger root tubers can be divided and then planted, or they can be planted directly after germination p>
2、 Growth conditions
1. There should be enough space for vegetative growth. Because the underground part of dahlia is relatively large, the flowerpot should be at least 20 cm above when planting; In the case of ground planting, the planting hole should also be more than 20cm p>
2. The bulbs of Dahlia are afraid of waterlogging, so the soil used must be loose and fertile sandy loam with particularly good drainage to prevent waterlogging during its growth p>
3. Before germination, it is best to soak its roots with fungicide to avoid wound infection caused by bacteria. Generally speaking, we can stabilize the temperature of germ at more than 15 degrees p>
4. The cultivation of Dahlia needs a long time of light, so after the root sprouts, it should be placed in a sunny environment to make it grow stronger p>
