Dahlias for Cut Flowers: How to Grow and Arrange Them

Dahlias are one of the most popular cut flowers, known for their large, colorful blooms and long vase life. If you're looking to grow dahlias specifically for cutting, there are a few things you need to know. In this article, we'll cover how to grow dahlias for cut flowers, how to harvest them, and how to arrange them in vases.

Growing Dahlias for Cut Flowers

When growing dahlias for cut flowers, it's important to choose the right varieties. Look for varieties that produce long, sturdy stems and large blooms. Some popular varieties for cutting include 'Café au Lait', 'Diva', 'Miss Amara’', and 'Robann Butterscotch'.

Dahlias prefer full sun and well-draining soil. Plant tubers in the spring after the last frost date, and be sure to water regularly throughout the growing season. To encourage more blooms, pinch off the first set of buds that appear, and deadhead regularly.

Harvesting Dahlias for Cut Flowers

Dahlias are best harvested in the morning or late evening when the weather is cool. Cut stems at a 45-degree angle, and place them immediately in a bucket of water. Bring them indoors and recut the stems under running water to prevent air bubbles from forming. Remove any leaves that will be below the water line in the vase.

When it comes to harvesting dahlias for cut flowers, timing is key. Wait until the flower buds have just started to open before cutting them, as this will ensure that they last longer in the vase. Use sharp, clean scissors or shears to make a clean cut at a 45-degree angle, and remove any foliage that will be below the water line in the vase.

It's important to keep in mind that dahlias continue to bloom throughout the season, so you don't need to cut all the flowers at once. Instead, harvest a few at a time to keep your vases full and your plants healthy.

When arranging dahlias in a vase, start with a clean vase filled with fresh, cool water. Remove any foliage that will be below the water line, as this can cause the water to become cloudy and reduce the lifespan of the flowers. Cut the stems to the desired length, and arrange the flowers in the vase, adding foliage or other blooms as desired.

To ensure that your cut dahlias last as long as possible, change the water in the vase every 2-3 days, recut the stems at a 45-degree angle, and add flower food to the water to help nourish the blooms.

Remember, the more you harvest your dahlias, the more they will bloom, so don't be afraid to cut them and enjoy them in your home or give them as gifts to friends and family

Arranging Dahlias in Vases

When arranging dahlias in vases, consider the size and shape of the blooms. Large, dinner-plate dahlias can be showcased alone in a vase, while smaller varieties can be grouped together for a fuller arrangement. Be sure to use a clean vase filled with fresh water, and change the water every two to three days.

Consider pairing dahlias with other flowers and foliage, such as roses, lisianthus, and eucalyptus, for a beautiful and unique arrangement.

Recap of Sustainable Agriculture

As with any plant, dahlias can benefit from sustainable agriculture practices. Consider using organic fertilizers and natural pest control methods, and choose varieties that are adapted to your local climate to reduce the need for excess water and resources. By adopting sustainable practices in your dahlia growing, you can help protect the environment and support a healthier ecosystem.

We hope this guide has helped you grow and arrange dahlias for cut flowers. With their stunning blooms and long vase life, dahlias are a wonderful addition to any home or garden.
