Asters delight us with their superb flowering, often spectacular in the garden.

In summary, what you need to know:

Last name : Aster
Family : Asteraceae
Type : Perennial

Exposure : Sunny
Ground : Ordinary, well drained

Flowering : Spring, summer, autumn depending on the species.

Planting, caring for and pruning asters are all things you can do to improve flowering throughout the seasons.

Planting asters

The planting period of aster varies depending on the species and takes place at fall or spring according to the flowering periods of each.

  • We plant in spring the aster that blooms until summer
  • Those that flower from September to October-November are planted in the fall.

It is important to follow certain rules to have a beautiful flowering and a good development of the asters.

  • Choose a sunny spot as this promotes the flowering of asters.
  • Avoid areas that are too humid, especially in autumn because aster is afraid of standing water
  • Favor well-drained soils
  • When planting especially but also during the flowering period, water regularly.

Multiply the asters

Asters are vigorous plants that quickly take over space, even having a tendency to deplete the soil in which they grow.

In the fall or preferably in the spring, you can multiply your asters by dividing their tuft.

  • Pull out the tuft that has become too invasive
  • Replant the clumps or offer them to replant them in good sunny soil
  • Water the newly planted asters
  • Add fertilizer to the old tufts that have remained in their place

Asters maintenance

Easy to grow and maintain, aster is considered an easy plant.

Cut the stems of faded flowers as you go, this promotes the appearance of new shoots and therefore the appearance of new flowers.

Cut back to the shortest in early winter, just after the first frosts.
This operation will help keep a compact clump and beautiful flowers during the next flowering.

Aster sick:

Some species of aster are quite sensitive to powdery mildew and, to a lesser extent, can also suffer from downy mildew

Aster in pot:

The potted aster has higher watering and fertilizer requirements.

  • Water when the soil is dry on the surface
  • Once every two weeks, add fertilizer for flowering plants to prolong flowering and renew flowers

To know about the aster

One finds the asters of small size to put them most often in edging or rockery, but also very large asters that will need to be staked.

Particularly honey-bearing, aster attracts bees.

While there are nearly 250 species of aster, we can say that all of them offer generous and often spectacular flowering.

Easy to maintain and with a certain hardiness, the aster is a staple of our gardens but also of our balconies and terraces because its pot culture is very easy.

Varieties and flowering:

For a flowering in spring or in summer you can turn to the Aster alpinus or tongolensis.

You will prefer the Aster divaricus or amellus for a summer flowering.

For a flowering in the fall, you will choose varieties like Aster novae-angliae or Aster novi-belgii.
