Dahlias bloom all summer long. The flowering period ends with the onset of frost. What you can do to ensure that the dahlias bloom for a long time and why the dahlias have no flowers at all.

Dahlias bloom from the summer months into late autumn

From when to when do dahlias bloom?

The blooming of dahlias in the garden begins in July. Dahlias that have been brought forward in the pot or on the balcony can also bloom earlier.

With the frost, the flowering period of the georgines is over. The non-hardy plants then have to be dug up and their tubers overwintered indoors.

Extend the flowering period of georgines

To ensure that the dahlias form as many beautiful flowers as possible for as long as possible, always cut off faded flowers as soon as possible. This also stimulates the willingness to bloom.

Only if you want to sow dahlias next year, leave a few flowers so that the seeds can ripen in them. Gather the seeds and sow them indoors the following March.

However, the sown georgines are not of a single variety.

Why don't some dahlias bloom?

There are mutliple reasons for this.

  • Too shady location
  • Too few nutrients
  • Too much nitrogen in the soil
  • Too dry or too wet soil

Too much nitrogen causes georgines to develop lots of leaves but no flowers.

Water dahlias so that the soil never dries out completely, but is also not too wet.

tips and tricks

A delicious liqueur can be made from the flowers of the dahlia. To do this, the flowers are carefully washed and, depending on the recipe, placed in kirsch, brandy or other alcohol. Dahlia liqueur needs a longer post-ripening period so that the aroma can develop fully.
