How to grow dahlia tubers

1. Planting method

When planting dahlias, it is recommended to germinate the root tubers first so that its buds can be clearly seen. There are two situations after germination. One situation is that the new buds can be used directly for cuttings, and the original bulbs can be replanted, so that reproduction can be carried out. You can also divide the larger tubers and then plant them, or you can plant them directly after germination.

2. Growth conditions

1. There must be a large enough space for nutrient growth. Because the underground part of dahlia is relatively large, the flowerpot should be at least 20 cm when planting; when planting in the ground, the planting hole should also be more than 20 cm.

2. The bulbs of dahlias are afraid of waterlogging, so the soil used must be loose, fertile and well-drained sandy loam to prevent waterlogging during the growth period.

3. It is best to soak the root tubers with fungicide before germination to avoid bacterial infection of the wound. Generally speaking, we can keep the temperature of the embryo stable at above 15 degrees.

4. Dahlias require long periods of light during their cultivation, so after the tubers germinate, they must be placed in a sunny environment to allow them to grow healthier.
