Did You Know?
1. Dahlias belong to the Asteraceae family, which also includes sunflowers, daisies, and artichokes.
2. The name “Dahlia” honors the Swedish botanist Anders Dahl, who is known for his extensive botanical studies in the 18th century.
3. Dahlias were originally native to Mexico, and were cultivated by the Aztecs for their decorative and medicinal purposes.
4. The Aztecs valued the dahlia’s tubers, which they used as a food source. They believed that consuming the tubers increased fertility and improved one’s ability to predict the future.
5. While most dahlias have a symmetrical flower arrangement, there is a unique variety known as the “cactus dahlia,” which features long, pointed petals that curve inward, resembling a cactus.
Choosing The Right Size And Type Of Dahlias For Your Garden
Dahlias are a versatile and beautiful addition to any garden, with different sizes and types available to suit your specific needs. When choosing dahlias for your garden, it’s important to consider their size and type.
-
Dwarf varieties are ideal for bedding, adding a burst of color to borders and containers. These compact dahlias are easy to maintain and provide a stunning display.

On the other hand, if you have a larger space to work with, you may want to consider taller varieties. Tree dahlias, in particular, can reach an impressive height of 5 meters, adding a dramatic touch to your garden.
Additionally, it’s worth noting that while dahlias are known for their beauty, not all varieties are attractive to pollinators. To create a pollinator-friendly garden, it’s recommended to include some single-flowered varieties. These varieties have open centers that allow bees and other pollinators to easily access the nectar and pollen. By incorporating these varieties into your garden, you not only enhance the beauty of your space but also support the vital role of pollinators in the ecosystem.

Creating A Pollinator-Friendly Dahlia Garden
Creating a pollinator-friendly dahlia garden is not only beneficial for the bees and pollinators but also adds an extra layer of interest and biodiversity to your landscape. To attract these important visitors, consider planting single-flowered dahlias alongside other pollinator-friendly plants such as lavender, salvia, and buddleja. By providing a variety of food sources throughout the season, you can ensure a steady supply of nectar for pollinators.
In addition to plant selection, it’s important to provide suitable habitat for pollinators. Adding bee-friendly features such as a shallow water source, rocks for basking, and nesting sites can encourage a diverse range of pollinators to visit your garden.
Remember to create a diverse and vibrant dahlia garden, as it will not only benefit these important creatures but also provide you with a constantly evolving and stunning display throughout the season.

Providing The Ideal Growing Conditions For Dahlias
Dahlias thrive in sunny and sheltered spots, so it’s crucial to provide them with the ideal growing conditions to ensure optimum growth and an abundance of flowers.
Dahlias require plenty of sunshine to produce vibrant blooms, so choose a location in your garden that receives at least 6-8 hours of direct sunlight daily.
When it comes to soil, dahlias prefer fertile, moist but well-drained soil. It’s important to prepare the soil before planting by incorporating organic matter such as well-rotted compost or manure to improve its fertility and moisture-retaining capabilities.
If the soil is heavy clay, adding horticultural grit can help improve drainage.
Spacing is also key when planting dahlias. They should be given plenty of space, with a recommended distance of around 60cm between each plant. Providing ample space allows the plants to grow and develop without competing for resources, ensuring healthy growth and abundant blooms.
Planting Dahlias: Buying Options And Proper Techniques
When it comes to planting dahlias, there are several options available:
- Purchase ready-to-plant dahlia tubers from garden centers, online nurseries, and specialist growers.
- Grow dahlias from tubers, rooted cuttings, or seeds.
If you choose to grow from tubers or cuttings, it’s important to ensure they are of good quality and free from any signs of rot or mold.
To ensure successful growth when planting dahlias, follow these proper techniques:
- Plant the tubers with the old stem or new shoot facing up, just below the soil surface.
- Water the newly planted tubers well and place them in a light, frost-free location.
If you opt to plant dahlias in pots, consider the following tips:
- Choose a large container at least 30cm wide and deep.
- Fill the pot with peat-free multi-purpose compost mixed with organic matter to provide optimum growing conditions.
- Provide support such as stakes or bamboo canes to prevent flopping, especially for varieties with large flower heads.
Note: Proper planting techniques and appropriate containers are crucial for successful dahlia growth.
Caring For Dahlias: Staking, Watering, And Winter Storage
Once planted, caring for dahlias is crucial for their overall health and performance. Dahlias, especially taller varieties, may require staking to support their growth and prevent flopping. Adding stakes or bamboo canes early in the growing season will provide the necessary support for the plants as they develop.
Proper watering is also essential for dahlias. Water them well once a week, ensuring the soil remains moist but not waterlogged. Mulching around the base of the plants can help retain moisture and suppress weed growth.
As the growing season progresses, it’s important to feed dahlias regularly with a high potash feed, such as tomato feed, once every fortnight. This will provide the necessary nutrients for healthy growth and abundant blooms.
In areas with frosty or wet winters, dahlias should be lifted in autumn. Cut the stems back and gently lift the tubers, then dry them upside down in a dry place. Store the tubers in a cool, dark, frost-free place until it’s time to replant in late March or early spring.
In milder areas with well-drained soil, covering the soil with mushroom compost and/or straw can offer protection to the tubers from frost.
By following these care tips, you can enjoy a stunning dahlia garden year after year, with healthy plants and an abundance of beautiful blooms.
