Dahlia Care: Cutting and Arrangement

While dahlia flowers make lovely bouquets, cutting a few to put in a vase is okay because doing so encourages the plant to produce more blooms. Make sure to remove any spent blooms as well.

The cool of the morning is the ideal time to cut flowers, including dahlias. Take stems that are long enough for your bouquet by cutting them horizontally with clean pruners or scissors. Since the buds will not open after being cut, choose open or nearly open flowers. If possible, aim to cut just above a group of leaf nodes and side buds. It would be best to cut as much length as you need for your bouquet. From those nodes, fresh shoots will develop.

Once the dahlia flowers have been picked, make a fresh horizontal cut at the base of the stem, and then place the cut ends in 2 to 3 inches of very hot (but not quite boiling) water. For at least an hour, leave the stems submerged in water. The blooms will last four to six days thanks to this hot water conditioning of the stems.

After conditioning the cut stems, remove any leaves below the water line in your vase. This holds for all bouquets, not just dahlias. Leaves that are submerged for an extended time decompose and release bacteria that reduce the flowers’ vase life. Every two or three days, replace the vase’s water and add a floral preservative to extend the life of the flowers. Even though dahlia arrangements are stunning, they can be combined with other cut flowers to produce stunning effects.

How to Extend Dahlias’ Vase Life

Dahlias in Bud Form

The dahlias in your garden will last longer if you cut them in the morning or at night, as suggested by The Backyard Gardener. According to the University of Georgia Extension, dahlias will not open if you cut them before they are fully bloomed.

To avoid damaging the delicate flower tissue, a clean, sharp knife should be used to make the cuts. Do not delay placing the flowers in a bucket of cool water to keep them from wilting.

Cut the Roots and Leave the Leaves

Keep the dahlia stems in the water while you use a clean, sharp knife to remove the bottom inch or so. It is best to cut the stem at an angle so that more of its surface area is exposed to the water in the vase.

Purge the Vase

Scrub the vase with a solution of one part bleach to 10 parts water after washing it with hot soapy water. It’s time to give the vase a good washing.

Prepare a Vase for the Dahlias

Warm water flows into the stems more quickly than cool water, extending the time the flowers can be displayed in a vase. A water temperature of about 110 degrees Fahrenheit is optimal. If you want your dahlias to last longer in a vase, you should get rid of any leaves or buds that will be submerged in water.

Preservative for Flowers

Dahlias should be placed in a vase with water and a floral preservative packet. Do not use homemade preservatives because they will not prolong the flowers’ life in a vase. Sucrose, acidifiers, and other ingredients in commercial products are all carefully calibrated to prevent bacterial overgrowth.

Refrigerate Flowers

Put the bouquet in the fridge for an hour or two before displaying it. Don’t put the flower arrangement near any heat sources, such as a radiator or a window that gets a lot of direct sunlight.

Changing the Water Regularly

Ensure the water level is checked daily and topped off if necessary. If the water smells or looks bad, change it out for clean water. Hold the dahlia stems under water while re-cut them to about 1/4 inch from the bottom.

Take Pleasure in Your Dahlias

The methods for extending cut flowers’ vase life are universal, including caring for dahlias. Find out which dahlias are the best for bouquets by doing some digging.

Dahlias are a great addition to any garden or bouquet because of their wide range of colors, shapes, and sizes, even if their vase life is shorter than that of more resilient cut flowers like zinnias. Whether growing dark red collarettes or purple cactus-type dahlias, you’ll find that dahlia cut flower production is well worth the effort.

Pruning Dahlias

  • When dahlia stems reach 16 inches, pinch off the flower heads (41 cm). The dahlia will produce its first four sets of leaves when it is young. To promote branching and a fuller plant with more flowers, pinch the top off the plant just above the fourth set of leaves.
  • The dahlias are currently in the rapid growth phase of their life cycle and will therefore recover quickly.
  • You can keep cutting back on new growth throughout the growing season to promote even more flowering.
  • You can trim away the new growth with your forefinger, thumb, or any other sharp tool.
  • If you want big blooms, each plant should only have 3–5 flowering stems. The dahlia’s energy is used up faster when it has more flowers, so the flowers get smaller—limiting the number of flowers on each plant to get the biggest dahlia blooms. This lets the plant’s energy go toward growing just a few large flowers.
  • If you do not mind smaller flowers, you may include up to 10 stems. If you desire more flowers and are less concerned with their size, simply prune back new growth occasionally. As the dahlia plant branches out, up to ten flowers may appear on a single plant.
  • Once flowers have begun to wilt, cut them off with scissors. Removing spent flowers, also known as deadheading, promotes the growth of new flowers. If you remove faded flowers throughout the season, your dahlias may continue to bloom well into the fall.
  • Since dahlia stems are tough and stringy, it’s best to use sharp scissors, pruning shears, or a knife to cut off the flowers.
  • Cut the flower stem back until it connects to the main stem.
  • When deadheading, leave rounded buds alone. When a flower’s petals have all fallen off, the closed calyx that remains is called the dead head and can look very similar to a new flower bud. On the other hand, a bud has a round shape, whereas a dead head has a cone shape.
  • Removing spent blossoms can stimulate the growth of new flower buds, but taking out the buds themselves will put off the blooming process.
  • Dahlias should have diseased parts lopped off. You can improve the look of your dahlias by trimming off any brown or shriveled sections with a pair of gardening shears. If you do this regularly, you can help keep plant diseases at bay.
  • Diseased parts of plants should be removed and disposed of properly, including leaves, buds, and stems.
  • If you notice knots forming in the plant, it’s best to uproot the whole thing and start over. The knots will first appear close to the roots and worsen over time.
  • If you notice the veins on your dahlias have turned a strange color, burn the plants and their roots immediately. Verticillium wilt can be identified by leaf discoloration and wilting, which can persist in the soil for years.
  • If you can’t burn these plants because of local regulations, put them in the trash.
  • If you notice mosaic mottling on the leaves of your dahlia, it is likely due to a virus spread by aphids, and you will need to destroy the entire plant.
  • Keep dahlias away from overhead sprinklers to avoid smut. Yellow spots appear on the leaves due to smut, and the leaves turn brown and dry. When water is poured from above, it can pool and promote the growth of smut.
