Core Guide: Let's explore the knowledge about whether you have to dig up dahlia tubers, with the editor's introduction!

Do you have to dig up the dahlia tubers?

Dahlia tubers do not necessarily have to be dug up. For example, in the southern regions, it's not necessary, but in the northern regions, it is needed. Because dahlia's cold resistance is not very high, the temperature in the north during winter is relatively low, so the tubers must be dug up in time to survive the winter. Moreover, the tubers are not cold-resistant, so after digging them out, they should be buried in sand and placed in a location with a temperature of about 5 degrees for maintenance.

Dahlias have been very popular in the country over the last two years, as many foreign varieties are now sold domestically. Compared to domestic dahlias, these foreign varieties produce even more beautiful flowers.

Their colors and varieties are diverse, so many people are instantly enchanted by the beauty of dahlias. So, do dahlias need to have their tubers dug up every year?

Do you have to dig up the dahlia tubers?

Dahlia tubers do not necessarily have to be dug up. In the south, you can leave them in the ground, but in the north, it is necessary. Because the temperature has now dropped below 0 degrees, if you are in the north, you should dig up the tubers for storage now. Therefore, in areas with low temperatures, you need to dig up the tubers in winter and then store them for planting the following year.

Dahlias have a very strong ability to multiply. This means that what starts as a small tuber in spring can become more than ten by autumn. At this rate, there will be no place to store all these tubers by next year.

How to store the dahlia tubers after digging them up

① Digging up the tubers

Let's first talk about digging up the tubers. Because dahlias are not cold-resistant, if the temperature remains below 0 degrees during winter, the tubers can be frostbitten.

So, for those in the north, you need to dig up the tubers. But if you're in the south, you can leave them in the ground over winter. Before digging, cut off the above-ground parts first, and be careful when digging because dahlias multiply vigorously. Use a small spade to gently loosen the soil to avoid damaging the tubers. After digging out the tubers, remove the soil from them and then place them in a shaded area to dry for 2-3 days before storing.

② Storing the tubers

Storing dahlia tubers is relatively easy. When I was a child in my hometown in the countryside, we used to store dahlia tubers in the cellar during winter.

However, it's rare to find cellars these days. So, you can prepare a large container, place the tubers in it, and then cover them with moist sand. Store the tubers in a cool, well-ventilated area with a temperature above 0 degrees to ensure they can survive the winter safely.

There is one very important thing to remind everyone: because dahlia tubers are connected to each other, try not to separate the small tubers when storing.

If they are not handled properly during separation, it can affect the germination rate the following year. If you want to plant them separately, you can do so in the spring by dividing the tubers with芽 points.

Because dahlias grow tall, it is recommended to plant them outdoors. Outdoor planting not only ensures robust growth but also a strong multiplication ability.
