With blooms that can grow up to 12 inches in diameter, these elegant flowers add a touch of grandeur to any garden. But what exactly are dinnerplate dahlias and how can we successfully plant and care for them?
Originating from Mexico and Central America, dinnerplate dahlias (Dahlia spp.) are a species of flowering plants that belong to the Asteraceae family. They are aptly named for their oversized blooms, resembling the size of a dinner plate, making them a focal point in any garden or floral arrangement. These beauties come in a wide variety of colors, ranging from vibrant reds and oranges to delicate pastel shades. Aside from their breathtaking size, dinnerplate dahlias also offer a delightful fragrance, attracting butterflies, bees, and other pollinators to your garden.
Now that we have a better understanding of what dinnerplate dahlias are, let’s explore the key takeaways when it comes to planting these magnificent flowers. In the following sections, we’ll delve into the ideal planting conditions, step-by-step planting instructions, and essential care tips to ensure your dinnerplate dahlias thrive and dazzle year after year. So, if you’re eager to turn your garden into a showstopper, let’s get started on this exciting journey of planting and nurturing these captivating blooms.
1. Dahlias should be planted in a sunny location with well-drained soil. It is crucial to choose a spot that receives at least six hours of direct sunlight every day to promote healthy growth and abundant blooms. The soil should be fertile and well-drained to prevent waterlogging, which can cause root rot.
2. Prepare the soil before planting by removing weeds and adding organic matter. Prior to planting, clear the area of any weeds or grass to avoid competition for nutrients and moisture. It is recommended to enrich the soil with organic matter like compost or well-rotted manure to improve its fertility and water-holding capacity.
3. Place tubers horizontally, ensuring the “eyes” face up, at a depth of 6 to 8 inches. When planting the dahlia tubers, lay them horizontally in the soil with the “eyes” or growing points facing upwards. Dig a hole that is 6 to 8 inches deep, making sure the tubers are adequately covered but not buried too deeply, as this can limit their growth.
4. Water dahlias regularly, aiming for moist but not waterlogged soil. Dahlias require regular watering, especially during dry periods or hot weather. It is important to maintain moist soil, avoiding both drought stress and overwatering, which can lead to disease. Water deeply, ensuring the moisture reaches the root zone, but do not allow the soil to become waterlogged.
5. Support tall dahlias with stakes to prevent them from toppling. As some dahlia varieties can grow tall and produce heavy blooms, it is essential to support them with stakes to prevent flopping or toppling. Stake the plants early in the growing season, gently securing them with soft twine or plant ties at regular intervals, and adjust the support as needed as the plant grows.
What are the Steps for Planting Dinnerplate Dahlias?
Choosing the Right Location
Dinnerplate dahlias require a location that provides full sun for at least 6 hours a day. Choose a spot in your garden that has well-draining soil to ensure the plants thrive. Avoid areas with strong winds that can damage the delicate stems of these flowers.
Preparing the Soil
Before planting dinnerplate dahlias, it is important to prepare the soil properly. Start by removing any weeds or grass from the area. Loosen the soil using a garden fork or tiller to a depth of 12-15 inches. Incorporate organic matter, such as compost or well-rotted manure, to improve the soil’s fertility and drainage.
Planting the Tubers
When planting dinnerplate dahlias, you should wait until all threats of frost have passed and the soil has warmed up. Dig a hole that is large enough to accommodate the tuber. Place the tuber in the hole with the eye, which is the bud where the stem will emerge, facing up. Cover the tuber with soil, leaving about 2 inches of space above it.
Spacing and Watering
Proper spacing is crucial for dinnerplate dahlias to reach their full potential. Place the tubers 3 to 4 feet apart to allow enough room for the large plants and their blooms to grow. After planting, water the area thoroughly to help settle the soil and provide initial moisture to the tubers.
Maintaining and Supporting the Plants
As dinnerplate dahlias grow, they may need support to prevent the stems from tipping over or breaking. Install stakes or support cages around the plants early in the growing season for the best results. Regularly check for any signs of pests or diseases and promptly treat or remove affected plants to maintain the overall health of your dahlia bed.
Harvesting and Storage
Once your dinnerplate dahlias are in full bloom, you can start harvesting the flowers. Choose flowers that are fully open and showing vibrant colors. Cut the stems at an angle, making sure each stem has at least one set of leaves. To store the harvested dahlias, place them in a bucket of water and keep them in a cool location until you are ready to arrange them.
Common Problems and Troubleshooting
While dinnerplate dahlias are generally resilient plants, they can still face some common issues. Keep an eye out for problems like powdery mildew, aphids, or tuber rot. Regularly inspect your plants for any signs of distress or disease and take appropriate measures to address the issues promptly.

2. When is the best time to plant dinnerplate dahlias?
The best time to plant dinnerplate dahlias is in the spring after the last frost has passed. This is usually around the end of May or early June in most regions. Planting them at this time ensures that they have enough time to establish themselves before the hot summer months.
3. How should I prepare the soil for planting dinnerplate dahlias?
To prepare the soil for planting dinnerplate dahlias, start by loosening it with a garden fork or tiller. Remove any weeds or grass from the area and amend the soil with organic matter such as compost or well-rotted manure to improve its fertility and drainage.
4. How deep should I plant dinnerplate dahlia tubers?
Dinnerplate dahlia tubers should be planted about 6-8 inches deep. Dig a hole wide enough to accommodate the tuber and gently place it in the hole with the eyes facing up. Cover the tuber with soil and lightly firm it to ensure good contact between the tuber and the soil.
5. How often should I water dinnerplate dahlias?
Dinnerplate dahlias need regular watering, especially during dry periods. Water deeply once or twice a week, ensuring the soil remains consistently moist but not waterlogged. Avoid overhead watering as it can cause the flowers to become damaged or prone to diseases.
6. How should I support the tall stems of dinnerplate dahlias?
The tall stems of dinnerplate dahlias may require support to prevent them from toppling over. Use bamboo stakes or other types of stakes to provide support. Insert the stakes into the ground near the plants and gently tie the stems to the stakes using soft plant ties or twine.
7. Do dinnerplate dahlias require special fertilization?
Dinnerplate dahlias benefit from regular fertilization to promote healthy growth and abundant blooms. Use a balanced slow-release fertilizer or apply a water-soluble fertilizer every 4-6 weeks during the growing season. Follow the package instructions for application rates and timings.
8. Should I deadhead the spent blooms of dinnerplate dahlias?
Deadheading the spent blooms of dinnerplate dahlias is recommended to encourage continuous blooming. Remove the faded flowers by cutting the stem just above a set of leaves or lateral branch. This allows the plant to redirect its energy into producing new blooms instead of forming seeds.
9. Can dinnerplate dahlias survive the winter?
Dinnerplate dahlias are not winter hardy in most regions and require protection to survive the winter. In colder climates, carefully lift the tubers after the first frost, remove excess soil, and store them in a cool, dry location over winter. Alternatively, you can cover the plants with a thick layer of mulch to insulate them from the cold.
10. How do I divide dinnerplate dahlia tubers?
To divide dinnerplate dahlia tubers, wait until spring when new growth starts to emerge. Carefully dig up the clump of tubers and separate them using a sharp, sterile knife. Each tuber division should have at least one eye or bud and some roots. Replant the divisions following the same planting instructions as for whole tubers.
