Sunflowers can easily be grown in pots or tubs on the balcony. However, they do not grow as large as they do outdoors. Since it is often very drafty on the balcony, you should use small varieties to be on the safe side. How to take care of sunflowers on the balcony.
The bigger the pot, the bigger the sunflowers will be on the balcony
Select short-growing varieties
Tall sunflower varieties do not reach their full height on the balcony. The pots are usually too small for this, so that the roots cannot spread properly.
It is therefore better to sow short varieties such as "Double Dandy", "Teddybär" or "Gelber Knirps". These sunflower varieties get by with less space.
The bigger the pot, the bigger the sunflower
To plant sunflowers on the balcony, the planters should be as large and, above all, as deep as possible.
Balcony boxes (€109.00) are not suitable for growing sunflowers because they are simply too low.
The planters need drainage holes so that rain and irrigation water can drain off. Even if the sunflower likes it moist - you won't get waterlogged.
A good location on the balcony
- Very sunny
- Warm
- Little draft
The sunnier the location on the balcony, the better the sunflowers will thrive. Make sure that the pots are not directly in the draft.
Once the flowers have grown and large, heavy flowerheads have formed, a stronger gust of wind can break the stems.
If you can't provide a sheltered spot, tie the sunflowers to support pillars.
Caring for sunflowers properly on the balcony
Potted sunflowers need a lot of water. Water at least every morning on rainy days. In very dry, hot summers, you often have to water again in the afternoon.
Sunflowers on the balcony need a lot of nutrients. Fertilize the plants at least once a week, preferably twice a week, with liquid flower fertilizer. (€1.95)
Sunflower seeds that you grow on the balcony should not be eaten or fed to birds or pets. They are often stressed by hormones.
tips and tricks
The blossom of the sunflower is always aligned with the path of the sun. During the day, the flower head rotates from east to west. In French, sunflowers are therefore also called "Tournesol" = "Turn to the sun".
