Dahlias are bright flowers that grow in Mexico. These plants are among the most sought-after in summer because their expected blooms appear precisely then — very noticeable and lasting until autumn. We can see them in pink, lilac, white... and other shades. Learn how to care for them and get stunning dahlias.

Dahlia flowers are quite large, vividly colored, and come in many shades. In very hot weather, dahlias may bloom after summer when temperatures become warmer and more pleasant for them — that is, already in autumn.

HOW TO CARE FOR DAHLIAS?

Dahlias require two very important things: lots of light and water. Here are additional care details:

LIGHT

Dahlias need a lot of light, especially if we want vibrant flowers. To get good light exposure, it's best to place them near a window or in a well-lit area inside the house. In case of very bright light, choose semi-shaded spots — both indoors and outdoors. It's also important to find a spot protected from the wind, as strong winds can damage dahlias and their flowers.

WEATHER

Moderate climate is ideal for dahlias, although these flowering plants tolerate both heat and cold well. They can withstand light frost down to -5ºC.

COMPOST AND FEEDING

These plants prefer soil rich in organic matter. When preparing the soil before planting, remove any old earth or substrate to ensure it's well-loosened and has optimal drainage. As for watering, dahlias are quite heat-tolerant, but regular watering will help them thrive. Always water at the base and avoid wetting leaves or flowers to prevent excess moisture, especially in summer when watering frequency should be increased significantly but overwatering must be avoided.

DISEASES AND PESTS OF DAHLIAS

Dahlias are not prone to pests. However, sometimes snails or slugs can be encountered. To avoid this issue, natural insecticides for these types of plants can be used.

HOW TO PLANT DAHLIA BULBS?

  • Do not plant dahlia bulbs too early — they do not tolerate cold soil well.
  • Plant dahlias in a spot with plenty of sunlight.
  • Sow them into rich, well-drained soil.
  • The planting hole should be slightly larger than the root system.
  • When planting, add a bit of compost or bone meal.
  • The hole should be 6–8 inches deep. Place the bulb side up and cover with 2–3 inches of soil.
  • As stems grow, gradually mound soil around them to the surface level.
  • Tall varieties of dahlias will require support stakes.

HOW TO TRANSPLANT DAHLIAS?

The best time is spring. Follow these steps to learn how to properly transplant dahlias:

  • Divide the bulbs.
  • Plant in pots or directly into garden soil.
  • Plant the bulbs approximately 6 inches deep.
  • Water moderately after planting and do not water again until the plant sprouts.
  • HOW TO CARE FOR DWARF DAHLIAS?

    As the plant grows, add soil until only 2 cm remains between the rim of the pot and the substrate. The watering system should be continuous — watering 3 times a week is sufficient.

    HOW TO GET DAHLIA SEEDS?

    After the flower appears, a seed head begins to form. When it fully dries out, we will find black dahlia seeds ready for sowing.
