Dahlias are very easy to propagate by dividing the dahlia tubers. This gives you two or more identical georgines that you can cultivate in the garden or in a pot. How to correctly divide dahlia tubers.

When the dahlia bulbs are large enough, the dahlia can be divided

When is it necessary to divide the tubers?

Sharing is particularly recommended when the tubers are very large and a little older.

If a dahlia has many large individual tubers, new tubers can hardly develop. They rob each other of nutrients. The shoots that grow from such tubers usually remain very thin.

Dahlia bulbs have a life span of a few years. If you are cultivating a particularly beautiful dahlia variety in the garden, you should divide it in good time to have young plants before the old tuber no longer sprout.

The best time to divide the dahlia bulbs

Divide dahlias in spring before planting them out. Sometimes it is advisable to take the tubers out of their winter quarters and let them grow indoors for a few days.

You can then better recognize which tubers are healthy. In addition, the beginnings of the buds can be seen on the root necks. This makes sharing easier.

How to properly divide the dahlias

Sharing is very easy. Either break off individual bulbs or take a sharp and, above all, clean knife and cut the bulb into parts.

Make sure that there is at least one eye, preferably several, on the root neck of each section. The new shoots will later sprout from these.

Treat cuts or fractures - yes or no?

Some gardeners recommend treating cuts and breakages with powdered charcoal to prevent disease from taking root. That's not really necessary. You should only protect very rare varieties.

Plant out divided georgines

  • Prepare planting holes or pot
  • Do not plant tubers too deeply
  • fill up soil
  • Approach cautiously
  • Water

Plant the dahlias immediately after dividing. Otherwise the tubers will dry out too much.

tips and tricks

Be sure to plant the georgia bulbs the right way round. The root collars must point upwards. Then the dahlia will bloom earlier because the shoots don't have to struggle through thick layers of soil.
