Grow dahlias at home: how to grow Dahlias from tubers

Dahlias are dazzling and colourful flowers that add a touch of sophistication and beauty to any garden. Growing dahlias from tubers is a popular and rewarding way to add these beautiful flowers to your garden. Here is a detailed guide to help you grow dahlias at home.

1. Choice of dahlia tubers

Before starting to grow dahlias, it is important to choose high quality tubers. Be sure to select firm and healthy tubers, free from disease or damage. You can buy dahlia tubers from local nurseries or garden shops.

2. Soil preparation

Dahlias thrive in well drained and fertile soil. Before planting your tubers, make sure to prepare the soil by plowing it deep and adding compost or manure to enrich the soil with nutrients.

3. Tuber planting

  • Dig trenches about 10-15 cm deep into the ground.
  • Place the tubers of dahlias in the trenches, spacing them about 30 cm.
  • Cover the tubers with soil and water generously.

4. Maintenance of dahlias

  • Water the dahlias regularly to keep the soil moist but not wet.
  • Remove weeds around dahlia plants to avoid nutrient competition.
  • Apply balanced fertilizer every month to promote healthy growth.

5. Plant support

Dahlias can become big and heavy enough, so it is important to support them to avoid them falling asleep. Use guardians or supports to help plants stay straight and bear the weight of flowers.

6. Protection against pests and diseases

  • Regularly inspect dahlia plants for signs of pests such as aphids or slugs.
  • Use natural methods or mild insecticides to control pests.
  • Prevent diseases by avoiding excessive watering and ensuring good air circulation around plants.

7. Harvest dahlia flowers

Dahlias produce beautiful and colourful flowers throughout the growing season. You can harvest the flowers once they are completely open to use in floral arrangements or simply to enjoy them in your garden.

By following these simple steps, you can grow dahlias from tubers successfully in your garden. Enjoy the beauty and diversity of the dahlias to add a special touch to your outdoor space.
