Dahlia packages 2025
After recently having to announce with regret that there will be no dahlia sale in 2025, we now have some good news for you!
Fortunately, we had secured a few varieties in a separate warehouse where we had a particularly large number of tubers. These were reserved for dahlia seed production. Instead of planting them ourselves, we decided to share them to offer you exclusive dahlia packages containing three varieties each! As a special bonus, you can get the packages at a lower price than if you bought them individually.
It all starts next Friday (28.02.25) at 9 a.m. The tubers will be
Shipped from 10.03.25 in frost-free weather!
More good news: We've been able to secure tubers of almost all varieties. When we divide them up for sale, there are always a few "shaky candidates." These aren't thrown away, but end up in our leftover bags. These bags have now saved us... everything is already potted for what we hope will be a successful cutting production. The first shoots are already visible, and we even expect to be able to offer most of our dahlia rarities as young plants at the Garden Magic at Hof Bissenbrook from May 2nd to 4th.
We hope you enjoy this opportunity and thank you for your support! 💕
More information coming soon – stay tuned!
Kind regards, Katja Hildebrandt & the Garden Magic Team

The Garden Magic Online Shop Planting and caring for dahlias
Möchtest du wunderschöne Dahlien selbst züchten? Das geht ganz einfach und du benötigst dafür nicht einmal unbedingt einen Garten – auch in Töpfen gedeihen Dahlienknollen prächtig.
Der ideale Zeitpunkt, um Dahlien im Freiland zu pflanzen, ist ab Mitte Mai, da die Dahlienzwiebeln sehr frostempfindlich sind. Wenn du früher starten möchtest, kannst du die Knollen bereits ab März an einem frostfreien Ort vorziehen. Die Auspflanzung ins Freie erfolgt dann ebenfalls ab Mitte Mai.
Dahlien lieben sonnige Standorte und bevorzugen einen gut durchlässigen, nährstoffreichen Boden. Während der Wachstumsphase ist es wichtig, den Boden regelmäßig aufzulockern, damit die Pflanzen kräftig wachsen können.
Ein wichtiger Tipp: Gieße die Knollen nicht direkt nach dem Einpflanzen, um Fäulnis zu vermeiden. Warte stattdessen, bis der Boden trocken ist und die ersten Triebe erscheinen. Außerdem empfiehlt es sich, verblühte Blüten und Samenansätze regelmäßig zu entfernen, um die Blühfreude deiner Dahlien bis zum Herbst anzuregen.
Mit diesen Tipps steht deinem blühenden Dahliengarten nichts im Wege!
Frequently Asked Questions (FAQ)
When can I plant dahlia tubers?
Dahlia tubers can be started indoors in a frost-free area starting in March and planted outdoors starting in May, as soon as night frosts are no longer expected. You can find out more in our Dahlia 1 x 1 .
What planting depth do dahlia tubers need?
The planting depth depends on the size of the dahlia tubers. 15 centimeters is ideal, about the depth of a spade. The tubers should be placed loosely in the hole, with the emerging shoots at the root collar covered with about 3 to 5 centimeters of soil. You can find more information in our Dahlia 1 x 1 .
What planting distance do dahlia tubers need?
Der Pflanzabstand zwischen den Dahlienknollen oder der Nachbarpflanze richtet sich nach der Wuchshöhe der Dahlien. Als Faustformel gilt, dass die Pflanzen halb so breit werden wie sie hoch werden:
- 80 bis 100 cm für hohe Sorten bis maximal ca. 180 cm
- 60 bis 70 cm für mittelhohe Dahlien bis 120 cm Höhe
- 30 bis 40 cm für niedrige Beet-Dahlien.
Do dahlias need to be fertilized?
If the soil is good, fertilization is not necessary. Otherwise, you should fertilize with a heaped tablespoon of organic fertilizer or a complete mineral fertilizer two to three weeks after the shoots appear. This process can be repeated in July, before flowering begins. In the fall, you should stop fertilizing to allow the tubers to ripen more quickly.
Are dahlias hardy, or do I have to overwinter the dahlia tubers?
Although dahlias are perennial, they are not winter-hardy in German climates. After the first frost, you should cut the plants back to about 15 centimeters. Leave the dahlia tubers in the ground for about another week to allow them to fully ripen. In dry weather, carefully lift them with a digging fork and gently shake off the soil. Store the dahlia tubers in a frost-free, cool, and dry place, such as a shed or cellar. Temperatures between 4 and 8 degrees Celsius are ideal. Remember to label the tubers so you can distinguish between the varieties next year.
