The right time to sow
The verbena can be sown outdoors from late April to mid-June. If you prefer to do it at home on the windowsill, you can start from February until April at the latest.

Preculture: from the seed to the seedling
When you have obtained the seeds, do the following:
- Fill the seed tray with nutrient-poor substrate
- Press the seeds into the soil and cover a maximum of 5 mm with soil (light germs)
- Moisten well with water from a plant spray bottle
- put in a warm place (temperature of 20 ° C)
- keep moist over the next few weeks
- the seedlings appear after 12 to 20 days
When sowing or pricking out outdoors, you should ensure a distance of 25 to 30 cm between the individual verbena plants. If the verbena is to grow in the pot, it should be deep enough because the plant will develop long roots.
Then: the right choice of location
After the ice saints in May, the verbena can be planted out or relocated to the balcony. The choice should be made on a sunny location. Alternatively, a partially shaded location can be chosen. But be careful: the sunnier, the bigger and more blooming the verbena becomes. In general, the site should be in a location protected from the wind.
In order to keep the subsequent maintenance effort low, it is advisable to pay attention to the substrate. The soil should be well drained so that waterlogging cannot build up. A lean to moderately nutrient-rich and humus substrate with a dry to moist environment is also advantageous.
Tips & Tricks
As soon as the verbena plants have reached a height of 8 cm, you should peel them off. As a result, they branch out better.
