Dahlias, also called georgines, originally come from Mexico. There they grow in moderately acidic soil where water does not accumulate. Above all, the flowers have it very warm and sunny there.

Dahlias like it sunny, always slightly humid and warm

A place in the Sun

In order for dahlias to develop many flowers over a long period of time, they need a location that corresponds as closely as possible to their homeland. Your demands on the location are:

  • Warm
  • Sunny
  • Nutritious Earth
  • Moderately humid
  • Never completely dry

Therefore, plant georgines as sunny as possible. If you grow dahlias in pots, place the tub on the patio in direct sunlight. The shadier the location, the fewer flowers the dahlias will develop.

Provide wind protection for large-flowered varieties

Depending on the variety, dahlias develop very small to almost plate-sized flowers. Large-flowered varieties should be protected from the wind so that the flowers do not break in the wind. To be on the safe side, you should tie them to supports.

Good, nutritious soil preferred

Soil that dahlias thrive in is nice and loose, allowing the tubers to spread out. Rainwater or irrigation water must not accumulate because the dahlia tubers will then rot.

Dahlias thrive best in soil with a pH of around 6.5.

Fertilize if necessary

Before planting, you should ensure that the soil receives enough nutrients. Put compost, cattle manure (€18.80) or horn shavings (€32.93) in the planting holes.

When you fertilize your georgines later, use only low-nitrogen organic fertilizers.

tips and tricks

Mulching is not recommended for dahlias. They increase the risk that the soil will become too moist and the tubers will rot. The mulch material also attracts snails and voles.
