Dinnerplate Dahlia Flowers: Growing Dinnerplate Dahlia Plants In The Garden

How big are dinnerplate dahlias? The name says it all; these are dahlias that produce huge blooms of up to 12 inches (30 cm.) across. Like other dahlias, these flowers bloom consistently for weeks and add beautiful color to beds. They are also great for cutting and making stunning floral arrangements.

What are Dinnerplate Dahlias?

The dinnerplate dahlia (also spelled dinner plate) is simply a variety of dahlia that produces big, plate-sized blooms. You can find them in a range of colors and forms, and they are essentially just larger versions of the many varieties of dahlia. Dahlias are already spectacular and showy flowers, so adding dinnerplate varieties to your beds adds even more drama.

Dahlias offer a greater range of color and form than most other flower types, so if you want some dinnerplate blooms in your garden, you have a lot of options. Some examples of spectacular dinnerplate dahlia flowers include:

  • ‘American Dream’ – This variety produces large pink double blooms with darker pink stripes.
  • ‘Babylon Bronze’ – This one is also a double bloom, but it comes in a stunning pale orange color.
  • ‘Taihejo’ – ‘Taihejo’ flowers are streaked with pink and white and have petals that are twisted.
  • ‘Café au Lait’ – This subtle stunner produces creamy white to peach flowers.
  • ‘Contraste’ – ‘Contraste’ flowers are deep red with white at the tip of each petal.

Growing Dinnerplate Dahlias

Dinnerplate dahlia care is just about the same as caring for any type of dahlia. Because the blooms are so large, though, staking and support may be more important with these varieties. Watch your flowers and use stakes or some other type of support if they start to lean or flop over.

Whether you’re starting from seed or transplants, don’t put your flowers outside until you are sure there will be no more frosts. To get the biggest blooms from your dinnerplate varieties, choose a sunny spot with rich soil that drains well. Soggy soil will stunt their growth. These plants grow tall, up to four feet (1.2 m.), so also choose a site where they won’t overshadow other plants.

Your soil for growing dahlias should be rich, but these flowers will also respond well to regular fertilizing. Use a typical flower fertilizer about twice a month. Water your dahlias if they are not getting about an inch of rainfall per week.

Deadhead the spent blooms as they expire, and you will enjoy dinnerplate dahlias from midsummer and through the fall.

Step by Step Guide to Growing Dazzling Dahlias!

Dahlia blooms come in a dazzling array of colors, flower forms and sizes, from dwarf dahlia plants topping out at 12-14 inches tall – perfect for window boxes and containers – all the way up to dinner plate dahlias and “over the top” dahlias with blooms fully 12-14″ across!

Dahlias produce their magnificent blooms from early summer right on until frost, filling your garden with color and your vases with beauty for months at a time. Knowing this, many people plant dahlias every spring, hoping for spectacular results, only to get tall, spindly plants flopping over in the mud instead. Dahlias are not difficult to grow, but they do require some attention, preparation and care to become the deserving center piece of your garden – and we will cover all of that, step by step, right here!

Don’t let the length of this post deter you. The payoff of beautiful dahlias is so great, and the potential disappointment so deep, that we are being extra thorough. You might prefer to review our infographic for the dahlia planting steps right here. You can do this! 🙂

Dahlia Planting Guide

At least 80% of the success of your dahlias takes place when you first plant them!

Where and When to Plant Dahlias:
  • Start with large, healthy dahlia tubers. Good tubers will produce not just this year, but for many to come. Even in bitterly cold climates, dahlia tubers can be stored for the coming spring. Quality matters, so get your dahlia tubers from a source that provides great quality.
  • Plant your dahlias after the last frost. The ground temperature should be about 60°F.In cold winter climates, you can plant your dahlias indoors for a jump on the growing season. When you are ready to move them outdoors, follow the advice in this planting guide.
  • Full sun for the best bloom production. Plant your dahlias where they will get 8 hours of direct sun each day. If you are in a very hot climate, be sure to provide morning sun for your dahlias, with afternoon shade.
Soil Preparation for Planting Dahlias:
  • Break up the soil where you will plant your dahlias, working in some compost to improve the nutrition and drainage. Do not bring in “new” soil. The herbicides and fertilizers so often used in packages soil will damage your newly sprouting dahlias.
  • Dig a hole about 4-7 inches deep, wide enough to spread out the tubers.
  • Work bone meal into the soil about 1 inch below where you will plant the dahlia tubers. sprinkle about 1 inch of soil on top of it, before planting your dahlia tubers. Bone meal will nourish the tubers and the root structure of your developing plants. Beware of pets and other animals becoming attracted to the bone meal you add. Add ground pepper to the bone meal where foraging carnivores are a nuisance.
Planting Dahlia Tubers:
  • Leave dahlia tubers attached, do not pull them apart, or cut the tubers like you would potatoes, just plant each clump of tubers intact, spreading them out in the hole, with the eyes facing up.
  • Plant dahlia tubers 4-6 inches deep, 12-24 inches apart, depending upon the mature size of the plant. Dwarf dahlias that grow up to 14 inches tall should be 12 inches apart. 3 foot tall dahlias, should be planted 18 inches apart. Give dinner plate dahlias a full 24-30″ spacing between plants.
  • Position the stakes or support structures at the time you plant your dahlia tubers. More information on how and why to stake dahlias follows below.
Planting Dahlias in Containers:

  • Dwarf dahlias, like the Gallery series, will grow and bloom beautifully in 12″ containers. Allow 1 tuber clump per container, and plant as above.
  • Larger dahlias can be grown in larger containers, like whiskey barrels. You can successfully grow 3 full sized dahlia plants in a whiskey barrel.
  • Maintain an even moisture for your dahlias in containers. The soil should be cool to the touch, not wet or muddy.
  • Plan to fertilize container grown dahlias at least twice a month with a low Nitrogen formula.
  • Add the support structure to the container at the time of planting your dahlias.

Stake Dahlias to Support Big Blooms
  • Add your dahlia support structure when you plant the tubers! Dahlias that grow two – three feet tall or more should be staked to support the wealth of blooms that will develop.
  • Stake now to avoid damaging the tubers. Adding a support structure after the dahlia plants are partially grown really risks damaging the tubers with an errant stake. Instead, add the support structure at the time of planting to both ensure a successful harvest and to minimize work down the road.
  • There are a variety of options for staking your dahlias. Bare branches from garden trimmings, wooden stakes with twine crossed at several levels between each stake, even tomato cages make quick and easy dahlia support structures. Don’t be dismayed by the looks of your stakes before the dahlia grows. The foliage will soon obscure the supports, and the incredible blooms to follow will be well worth the effort!
Watering Dahlias
  • If your garden has not had rain for several weeks, water in your dahlia tubers when you have finished planting them. If you have had rain recently, leave the tubers dry. After planting, wait for the dahlias to show top growth before watering again.
  • Water your dahlias in relation to their size. Growing dahlias should be watered more as they grow larger. Once a week when they first sprout, with more water as they grow, until you water deeply 2-3 times per week as they flower.
  • Adjust watering for your dahlias’ conditions. Dahlias growing in containers or very hot climates will need more frequent watering than those growing in the ground where temperatures are more mild.

*Congratulations! Your dahlias are now planted perfectly for success! Just a bit more care for truly spectacular results for months to come!*

Topping Dahlias and Pinching Dahlia Plants
  • Pinching or “topping” dahlias results in shorter, sturdier, fuller dahlia plants that produce more blooms. This is true for the dwarf dahlias, the dinner plate dahlias and every style and size in between.
  • Pinching back your dahlias should be used in two ways. First, when your plants are 12-16″ tall, pinch off the top of the plant just above the 4th set of leaves, as shown in this diagram to the right. Pinching off the top of the plant is referred to as “topping” your dahlia plant.
  • Top your dahlia plant cleanly, using shears, scissors or your fingers, taking care not to tear the stem.
  • Removing the top of your dahlia plant temporarily refocuses the plant’s energies from producing flower buds, and instead the plant develops more stems and more foliage – capable of producing and supporting many more blooms. You and your garden will benefit from topping your dahlias for months!
  • At this stage, your dahlias are growing quickly, rapidly recovering from the pruning.
  • As your dahlia plant grows, and sets flower buds, continue to pinch back new growth for more bloom production. Where multiple buds are formed, pinching back a few buds will result in larger blooms for those that remain.
  • Cutting dahlias for your vase will have the same effect as pinching back your dahlia plants.
  • Dead head your dahlias. As dahlia blooms fade, pinch back the spent blooms. Known as “dead heading”, removing spent dahlia blooms prevents production of the seeds the plant is producing to aid in reproduction. By removing the spent blooms, you are causing your dahlia plant to produce more blooms in its quest for reproductive seeds.

There you have it! These simple steps are the “secret” to spectacular dahlias!

I would love to learn what you think – will you be planting dahlias this spring? I cannot decide between the perfect blooms of Dahlia Edge of Joy and the enormous, casual blooms of Dinner Plate Dahlia Mick’s Peppermint. I may just have to plant both! 🙂

I will be posting information about storing your dahlia tubers for the winter in a few months. In the mean time,

Happy gardening!

  • Garden care: Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being over-crowded. While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch. In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.

Dahlia Bulbs – Dinnerplate Mix Pre-Sale Now; Ships Spring 2020

Dahlia Bulbs (tubers) are available in many catching colors and exotic shapes to give you a spectacular show of color in borders, beds or even containers. They have long been a favorite with gardeners as they are hardy and low maintenance. Dahlias will yield beautiful blooms from mid-summer through fall.

When to Plant your Dahlia Bulbs:

Unlike other bulbs such as Tulips, Dahlias like warm soils so plant Dahlia bulbs during the warmer and longer days of spring. Dahlias are usually planted about the same time you would plant your vegetable patch. Dahlia bulbs can be planted as late as mid-June in most parts of the country.

Where to Plant you Dahlia Bulbs:

Dahlia is an accommodating plant – it will grow almost anywhere! Dahlias will thrive in full sun but can tolerate some partial shade – the more sun, the bigger the flowers. Try to select a location that receives at least 6 hours of sun, sheltered from the wind and with, and this is vital, good drainage.

How to Plant your Dahlia Bulbs:

Dig a hole twice as deep and wide as the Dahlia bulb. Put the tuber in the hole with the “eye” on the tuber facing up. The eye is the point on the shoulder, or crown, of the tuber from which the plant grows. If you are planting a number of dahlias in the same location, they should be separated by about 2 feet to give each plant room to grow. The shorter varieties can be planted closer together. Plan for the rows to be 3 to 5 feet apart depending on the size of the plant. Fill in with soil to just cover the top of the bulb. As you begin to see new growth appear, cover again with soil. Covering the stem gradually will allow the stem to strengthen so it can support the flowers. Unless it is a very dry spring, it is not be necessary to water at the time of planting. The tubers will begin growing with the warmth and moisture in the soil. It is vital that they form a root system early in their planted life to assure a strong and healthy plant. Watering at the time of planting may encourage rot but as soon as your Dahlias are growing above the ground, water deeply to encourage strong roots.

How to Care for your Dahlia Bulbs:

Young dahlia plants do not need a lot of water; in fact, excessive water can lead to rotting of the plant. For larger plants, a good rule of thumb is to water if the rainfall is less than one inch in seven days. Pots require more regular watering. As the plant grows, remove any broken or damaged foliage. Good air circulation, especially near the ground is needed by the plants to prevent powdery mildew. Once the plants are several feet high the lower leaves can be removed to increase air circulation. Your dahlias will continue to bloom prolifically right up until frost. A heavy frost will kill the plant so you may want to dig the half a dozen or more tubers the plant has produced. Those tubers can then be stored and grown next spring!
