Growing Dazzling Dahlias for Vibrant Color in Your Garden

Growing Gorgeous Dahlias

Dahlias are one of the most stunning flowers you can grow in your garden. Their diversity and brilliance of color make them a must for any gardener looking to make a bold statement. Though they originate from Mexico, dahlias grow beautifully in most climates and soil types.

Choosing Dahlia Varieties

With over 40 species and 20,000 cultivars, there are countless dahlia varieties to choose from. Dahlias come in every color except blue, and have flowers that range from tiny 2-inch lollipop-style blooms to giant 15-inch dinner plate blossoms. Popular types include:

• Cactus dahlias - Distinctive spiky, rolled or curled petals
• Decorative dahlias - Broad, flat, open centered flowers
• Ball dahlias - Round, globe-shaped flowers
• Pompon dahlias - Small, ball-shaped flowers with tightly rolled petals
• Single dahlias - Daisylike flowers with a central disc

Consider the size, color, and bloom time you want when selecting varieties. Dwarf bedding dahlias are great for containers, while tall varieties make stunning cut flowers.

Planting and Care

Dahlias grow from tubers, not seeds. Plant them outdoors after all danger of frost has passed. Choose a sunny spot with fertile, well-draining soil. Dig a hole 6 inches deep and set the tuber in with the eye facing up. Cover with 2-3 inches of soil.

Pinching out the center growing tip when plants reach 12 inches tall encourages bushier growth. Stake taller varieties to prevent toppling. Dahlias are heavy feeders--fertilize them regularly with a balanced flower fertilizer. Water them during dry spells to keep the soil moist but not soggy.

Blooming and Harvesting

Most dahlias start blooming 8-10 weeks after planting and continue until frost. Deadhead spent blooms to encourage more flowers. Use a sharp knife or pruners to cut flowers just above a set of leaves.

For the best vase life, cut stems early in the morning while it's cool. Place immediately in water. Strip off the lower leaves and recut the stems under water. Dahlias can last up to 7-10 days in a vase with proper care.

Overwintering Dahlias

Dahlias are tender perennials. In cold climates, you'll need to dig up the tubers and store them over winter. After the first light frost blackens the foliage, cut stems back to 6 inches. Dig up the clumps carefully, shake off excess soil and allow to dry for a day or two. Remove any rotten tubers.

Store the tubers in a cool, dry place over winter. Pack with vermiculite, peat moss, or wood shavings. Replant the following spring after the chance of frost has passed. Dividing the tubers every few years will stimulate growth.

Dazzling Dahlias Bring Nonstop Color

Dahlias are the perfect flower for gardens, bouquets, and arrangements. Their outrageous colors and forms add pops of excitement to any setting. With just a bit of care, these beauties will reward you with an abundance of blooms from midsummer until fall frost.

Let dahlias bring their vibrant spirit to your garden this season! Just beware—their captivating charms might just make you a dahlia devotee for life.

FAQs

What are the best dahlia varieties for cut flowers?

Tall, large-flowered dahlia varieties like dinnerplate and cactus dahlias produce stunning cut flowers. Good cutting choices include 'Cafe au Lait', 'Karma Choc', and 'Kelvin Floodlight'.

Should I deadhead my dahlias?

Yes, deadheading spent blooms encourages more flower production. Use pruners to snip off faded flowers just above a set of leaves.

How much sun do dahlias need?

Dahlias require a minimum of 6-8 hours of direct sunlight per day. Morning sun is ideal. Too much shade will result in sparse, weak growth.

Is it necessary to stake dahlias?

Staking is recommended for taller, larger-flowered dahlia varieties to prevent toppling over in wind and rain. Use sturdy stakes and plant ties to support the stems.

How do I overwinter dahlia tubers?

After frost blackens the foliage, carefully dig up the tubers. Allow to dry for 1-2 days. Store in a cool, dry place like a basement or garage over winter. Pack with peat moss or vermiculite.
