Growing sunflower as a potted plant - tips on pot size, sowing, location & care

If you don't have enough space for sunflowers in the garden, you don't have to do without them. Sunflowers also thrive in pots and tubs. Only the right varieties are important for this.

Special sunflowers also thrive in pots. We are familiar with sunflowers. They like to stand in gardens and front gardens, towering over bushes, rose bushes and sometimes far over fences and hedges. Their heads bow towards the sun and it almost looks as if they greet the sun in the morning and say goodbye in the evening.

But sunflowers don't necessarily need the garden. They also thrive in pots. Provided that you adhere to our tips.

Plant or pull yourself?

Sunflowers that have already been brought up and planted in decorative pots can be easily bought in stores. However, you also have the option of sowing sunflowers independently and raising them in a pot. The seeds are available in nurseries, hardware stores and specialist shops. Of course, you can also collect sunflower seeds from the garden and sow them in a flowerpot.

However, the joy of the flower will only last for a short time, unless you pull the plant directly in a large bucket. The smaller varieties are more suitable for flower pots on the windowsill or on the kitchen table:

  • Pacino - when fully grown it reaches a height of about 30 centimeters (e.g. here)
  • Teddy bear - at forty centimeters, this sunflower is suitable for medium-sized pots (e.g. here)
  • Big Smile - this variety represents the garden sunflower. The flower is sunny yellow and is described by a black circle in the middle. Height of growth: up to 30 centimeters
  • Sunspot - this species grows up to 60 centimeters and has a large flower. Suitable for large flower pots and tubs (e.g. here)

You don't need much to sow. A sufficiently large flower pot with a drain opening, potting soil and a bowl that catches the superfluous irrigation water are all that is needed. You can grow several plants together in one pot. Just keep in mind that in this case you have to choose a larger pot. If the pot is too small, you have to repot the plant, which can damage the sunflower. After all, sowing is very easy:

1 Put soil in the flowerpot. If you have the option of creating a drainage, we recommend this variant. To do this, put stones, a little styrofoam, potsherds or gravel on the bottom of the pot.

2 Fill the potting soil directly onto the drainage. Compost can be used as potting soil, which you can mix with ordinary potting soil.

3 Now the seeds come into play. Depending on the size of the pot, put between two and ten seeds in the ground. Select sowing in pairs. Since mostly not all seeds germinate, this procedure later gives a pleasant growth pattern. Just press the seeds into the earth.

Now all you have to do is water the plant.

From seeds to plants

Sunflower seeds need a lot of water to germinate. Therefore, you should water the plants regularly and a lot. We recommend an interval of two days unless the soil dries out. The sunflower needs permanently moist soil to germinate and form seedlings.

As a rule, you will see within eight days whether your work has been successful. As soon as you discover the first tender plantlets, wait a few more days for them to develop. Depending on how many seeds have sprouted, you must now carefully remove individual seedlings from the pot and put them in your own pot:

4 The seedlings are planted about 2.5 centimeters deep in the loose soil. So that they have enough space to thrive, a distance of ten centimeters is advisable.

5 Regularly water both the newly planted seedlings and the seedlings that were sown first.

6 The watering interval increases as soon as the plant reaches a height of thirty centimeters.

Location for the sunflower

Actually known as a typical garden plant, the sunflower prefers a bright and sunny location in the plant pot. If possible, choose a windowsill that is in sunlight for most of the day.

Caution: The sunflower is not sensitive to the sun, but does not tolerate shade. Nevertheless, you should make sure that the leaves do not come into contact with a window pane, since the heat is too great.

Caring for the sunflower in the pot

Light and water are the two elements that a sunflower cannot do without - this also applies to potted plants. Always be careful not to let the soil dry out and water adult plants daily. If you give too much water, your drainage or the drain of the pot comes into play.

It is advisable to feed your sunflowers with a nitrogenous fertilizer weekly. This does not necessarily have to be artificial, even a slurry made from nettles, horn shavings or compost are suitable for nutrient supply.

" Watch out: The sunflower seeds of the small varieties are due to the breeding direction, which is often associated with the spreading of hormones, not eatable, You can therefore easily use artificial fertilizer.

Your sunflower needs no further care. You do not even need to remove faded flower heads, as they continue to ripen on the stem. The only reason you should use scissors is to dry the flowers. To do this, remove the flower before it has fully opened.
