Plantation of helenia

Helenia crashes ideally in spring because, although it will flower only in summer, it will be well rooted and will withstand the rigors of autumn and winter much better.

Well sunny and protected from the wind, helenia can flower until the first frosts.

  • Setting up the young plants in the spring
  • Favor an amended soil and well drained (not retaining water)
  • Choose a location sunny in order to promote flowering.
  • Water regularly after planting

Pruning, maintenance, watering of helenium

The helenium requires little care other than watering regularly if it isn't raining.

  • Remove the faded flowers as you go, this helps the appearance of new flowers.
  • Water when the soil is dry, especially for container use as chrysanthemums require moist soil to thrive.
  • It is not necessary not wet the foliage to prevent the occurrence of diseases such as rust or powdery mildew.
  • After the first frosts, when the flowers start to blacken, cut the stems low to the ground.

Every 2 to 3 years you can divide the tuft in spring or fall to regenerate the plant and restore vigor.

Common diseases in helenia

Elenia is quite resistant but sometimes subject to a few diseases and pests which are preventable, however, especially by avoiding wetting the foliage and by spacing each plant sufficiently so that they do not touch each other.

  • Powdery mildew : a whitish film covers the leaves and stems
  • Rust : pustules appear on the underside of the leaves
  • Aphids : leaves curl and eventually fall.

They have the advantage of bloom in summer and relatively late, until the month of November or December, and thus come to decorate our gardens advantageously when flowers start to be scarce.
