Planting and Care of Dahlia Flowers

There is little question as to why dahlias are a flower garden enthusiasts favorites. Proper care of planting and care of dahlia flowers make show-stopping garden additions.

Many of the dahlia species evolved from wild species in Mexico. The area near Mexico City had extremely hot days and but cold nighttime temperatures due to the ravines they were growing in. This might explain why the flowers bloom profusely during the Autumn months.

In the late 1800s, the double varieties were produced in Europe. Today, we have plenty of choices when it comes to selecting dahlia flowers.

Location & Soils To Grow Dahlias In

Dahlias grow well in full sun to partial shade. They should get six hours of sunlight a day. In warmer climates, afternoon shade can help the flowers by keeping them cooler. Afternoon shade can also improve the color and reduce fading in some blooms.

  • The dahlia is a fall-blooming plant & the location is best suited in your yard is where late autumn frost is light.
  • Prefer somewhat sandy soil but will grow nicely in heavy clay too.
  • Lighten soil with wood ash, sand or coarse manure.

Starting Tubers

Tubers should be started indoors about April 1st in a shallow box of sand or light soil. Place the box of tubers in a window that has good filtered light.

  • When young shoots begin to show, they should cut so that one or two eyes are allowed to remain on each piece; the eyes form on the collar.

Supporting & Growth Development

Dahlia Garden Flowers

The average root will make several shoots. Allow them to grow until they make the first set of leaves, by that time the strongest can be selected and the others cut away below the surface of the soil.

 

  • The rule is that one shoot is sufficient, but no more than two.
  • Tie the shoot to a stake when a foot high.
  • When you want the plant to branch out, pinch out the tip.
  • It is best to only allow 6-8 branches on each plant.

Winter Storage

Digging Up Dahlia Tubers

When the autumn frost arrives in October and kills off the foliage of the plant, it is time to pull up the tubers.

Many types of dahlias do not survive the snowy cold winters here. We have to lift them out of the dirt or purchase new ones come spring. I wrote up a quick guide to digging up and storing dahlias over winter.


Excellent Cut Flower Arrangements

Dahlia flowers have proven to make wonderful vase arrangements indoors.

  • Cut the flower stalk in the morning.
  • Place the stalk in water up to the height of the flower and placed in a cool location
  • If you have a hard stem variety place the stems in hot water and allow the water to cool naturally. After the water has cooled, place water with fresh cold water.
