Like a radiant sun in the midday sky, the sun's eye shines into the field of vision. It is popular as a bee pasture. But it is also valued by many gardeners as a guest in the perennial bed. How do you properly care for this perennial and what is really important?

The sun eye does not need much water

Casting the sun's eye - can it be so difficult?

The sun eye gets along with little water. But it doesn't like dryness. It also cannot make friends with waterlogging. It is best to keep the substrate moderately moist towards its roots! It is recommended to mulch the root area. Then the evaporation rate is lower.

As long as there is no drought, it is not absolutely necessary to water the sun eye. Only after planting does the sun eye need regular watering in order to be able to take root. Watering should be carried out up to 4 weeks later if there is no rain.

How often should you fertilize the sun eye and with what?

If you mulch the sun eye with lawn clippings or bark, you do not need to fertilize it. Note the following when you want to fertilize:

  • use organic or organo-mineral fertilizers
  • It is best to enrich the soil with compost before planting
  • well suited for fertilizing: compost, horn shavings, (32.93 €) liquid manure
  • Dose fertilizer depending on the nutrient content of the soil
  • once a year is sufficient
  • fertilize in spring

Does this perennial need winter protection?

The sun eye does not need to be overwintered. It is sufficiently frost hardy in this country. The sun's eye only reacts sensitively to winter moisture. It is therefore advisable not to cut back its old shoots until spring so that they can drain away the moisture in winter.

What pests and diseases can harm it?

Snails can appear as pests, especially when there is a lot of rain and the perennial is in the process of budding. You can collect the pests or render them harmless with slug pellets (7.49€). Diseases do not usually attack the solar eye because it is extremely resilient.

When and how is the pruning done?

In spring or alternatively after flowering in autumn, you should cut down your sun eye about hand high. To do this, take a pair of conventional pruning shears and gather up the old shoots with your hands before pruning them back. Then the sun's eye can drive out better.


If you regularly cut off the faded flowers, you will prolong the flowering period.
