Most flowering perennials have already said goodbye. But the asters don't give up, they hold up bravely. But it doesn't always stay that way. A transplant campaign can sometimes become vital.

The best time to transplant asters is in spring or autumn

Reasons that can speak for a transplant campaign

Professionals sometimes only replant their asters so that the plants get a new, loose and compost-rich soil and thus grow stronger again and subsequently flower more profusely.

The following aspects also make transplanting useful:

  • planted too tight
  • too half-shady/shady location
  • too windy location
  • bad growth
  • Disease infestation (aster wilt)
  • upcoming move
  • no more joy in the plant; give away

Make the choice of location beforehand

Even before you lift the aster out of the ground, you should know where you want to plant it. Not every location is suitable. These perennials need a lot of sunlight. They prefer a sunny location. High-growing varieties also need a sheltered place. Blue aster, white aster and wild aster can also thrive in semi-shade.

Prepare the ground

The next step is to prepare the soil at the selected location. Dig a planting hole. Loosen the soil in it properly. If the soil is very clayey, mix in some sand and humus! You can also put some compost in the planting hole.

Go into action: dig up, divide, transplant

In early fall or early spring, the time has come to take action. Keep in mind that the aster still needs some time to take root properly. If a frost period comes soon after transplanting, it can be helpless.

Lift the aster out of the ground with a digging fork. Now you can divide the perennial if you want. If roots have been injured, cut them back with a sharp and clean knife. Now it's off to the new location. The aster is planted there and then generously watered. If necessary, attach a support - done!


The distance to other plants should not be irrelevant! Therefore, when transplanting to the new location, keep a minimum distance of 30 cm to neighboring plants!
