Introduction
There is a unique sense of excitement that comes with planning a summer garden, and few flowers inspire as much joy as the dahlia. With their incredible variety of colors, sizes, and intricate petal patterns, these blooms are the highlight of the late-summer landscape. To enjoy a garden filled with dinnerplate-sized blossoms or cheerful border pompons, the process begins long before the first sprout appears. Success with these stunning plants starts with knowing exactly when to secure your favorite varieties.
At Longfield Gardens, we want to make the process of growing dahlias as straightforward and rewarding as possible. Choosing your tubers at the right time ensures you get the specific colors and forms you want while allowing for a stress-free planting season. This guide is designed for home gardeners who want to understand the seasonal cycle of the dahlia market, from the first winter pre-orders to the final spring shipping windows.
By understanding the timing of the tuber market, you can plan your garden with confidence. We will cover the best months to shop, why early orders make a difference, and how shipping schedules align with your local weather. Knowing when to buy is the first step toward a garden full of spectacular, high-quality blooms.
The Best Window for Buying Dahlia Tubers
The best time to buy dahlia tubers is during the winter and early spring months, typically from January through March. While dahlias are not planted until the soil is warm in late spring, the market for tubers moves much earlier. Because dahlias are grown from tubers that are harvested in the fall and stored over the winter, inventory is finite. Once a specific variety is sold out for the season, it usually won't be available again until the following year.
For most gardeners, shopping in January and February offers the perfect balance of selection and preparation. During this time, we provide a full catalog of options, ranging from the massive 'Cafe au Lait' to vibrant cactus-style dahlias. Buying early doesn't mean the tubers will arrive while the ground is still frozen; instead, it secures your "place in line" so that your items are reserved and ready to ship when the weather is appropriate for your area.
If you wait until the actual planting time (May or June) to start your search, you may find that many popular varieties are no longer available. While you can still find tubers later in the spring, your choices will be significantly more limited. By treating dahlia shopping as a winter activity, you ensure that your garden looks exactly the way you envisioned it.
The Dahlia Market Calendar
To help you stay on track, it is useful to look at the dahlia buying cycle as a seasonal calendar. Each phase of the year offers different opportunities for the home gardener.
Late Fall to Early Winter: The Preview Phase
During November and December, many gardeners are just finishing their fall clean-up. While it might seem early to think about summer flowers, this is when we begin updating our selections and preparing for the upcoming season. This is an excellent time to look through garden photos from the previous year and decide which colors or heights you want to add to your collection.
January to February: Peak Ordering Season
This is the most critical window for dahlia enthusiasts. Most major retailers and specialty growers open their pre-orders during this time. Because the demand for certain trendy colors and "dinnerplate" varieties is high, the best selection is always available in the first two months of the year. When you order during this window, you have the highest chance of securing every variety on your wish list.
March to April: The Transition Window
By March, the focus shifts from browsing to logistics. This is the last chance for a wide selection of tubers. It is also the time when shipping begins for gardeners in warmer climates. If you live in a region where the ground warms up early, buying in March ensures your tubers arrive just in time for your first planting window.
May to June: Last-Minute Finds
Once the traditional planting season arrives in the northern United States, the buying window begins to close. You can still find tubers during this time, and it is a great opportunity to pick up an extra variety or two to fill an unexpected gap in the garden. However, be aware that many of the most sought-after varieties will likely be sold out by this stage.
Key Takeaway: Think of dahlia buying as a winter hobby. Secure your favorite varieties in January or February to ensure you have the best selection for your summer garden.
Why Early Ordering Beats the Spring Rush
It can be tempting to wait until you see dahlia tubers on a shelf at a local store, but ordering online during the winter offers several distinct advantages. Gardening is most enjoyable when it feels organized rather than rushed, and early ordering provides that peace of mind.
Superior Variety Selection
When you shop early, you aren't limited to the few standard varieties found in big-box stores. You can choose based on specific attributes like stem length for cutting, pollinator appeal, or dramatic color shifts. If you have your heart set on a specific "look"—like a soft peach and cream garden—early ordering is the only way to guarantee you get the right tubers to achieve it.
Strategic Garden Planning
Knowing which dahlias you have already secured allows you to plan the rest of your garden more effectively. You can decide where your tall varieties will go to provide a backdrop for shorter perennials, or you can plan your color palette for the entire season. Having your "flower list" finalized in February makes spring much less hectic.
Managed Shipping and Logistics
Early orders are processed and organized by the time planting season arrives. At Longfield Gardens, we coordinate shipping based on your location. When you order early, your tubers are reserved in our climate-controlled facility in New Jersey until it is safe to ship them to your specific zone. This prevents the stress of hunting for plants when you should be outside enjoying the dirt.
How Shipping Schedules Affect Your Purchase
One of the most important things to understand when buying dahlia tubers is that the purchase date and the delivery date are usually weeks or months apart. This is a standard practice in the gardening industry designed to protect the health of the plants.
Dahlia tubers are sensitive to extreme cold. If they are shipped while temperatures are still well below freezing, they can be damaged in transit. To ensure your plants arrive in prime condition, we time our shipping based on the USDA hardiness zones.
- Warmest Zones (8-10): Shipping typically begins in early spring as these areas reach safe temperatures first.
- Mid-Range Zones (6-7): Shipping follows as the risk of a deep freeze during transit diminishes.
- Coolest Zones (3-5): These orders are shipped later in the spring to ensure the tubers aren't sitting in a cold mailbox or truck for too long.
We aim to have your tubers arrive about two weeks before the ideal planting time for your area. This gives you a little bit of time to inspect your order and prepare your garden beds. Remember that shipping dates are always estimates and can change based on the weather. If a late-season cold snap hits, it is common for shippers to hold packages for a few days to keep the tubers safe.
Understanding What You Are Buying
When you are browsing for tubers, you may notice different terms used to describe the product. Understanding these can help you choose the right timing and source for your needs.
Individual Tubers vs. Clumps
In the United States, dahlias are often sold as individual tubers. An individual tuber looks somewhat like a small sweet potato and must have at least one "eye" (a growth point) to produce a plant. Some European growers, including many of our partners in Holland, provide dahlia "clumps." These are one-year-old plants that consist of several tubers attached to a central stem.
Both individual tubers and clumps will grow into beautiful, full-sized plants. The primary difference is that clumps often provide multiple eyes, which can offer a bit of extra insurance for a vigorous start. Regardless of whether you buy a single tuber or a clump, the size of the tuber does not dictate the size of the flower. A small tuber can produce a massive six-foot plant just as easily as a large one.
Quality and Trust
When you buy from a reputable source, you are buying peace of mind. We maintain a trial garden to evaluate how different varieties perform, ensuring that what we offer is reliable for home gardeners. We also stand behind our quality with a 100% guarantee. This means that your tubers will arrive true to their variety and in healthy condition. If there is ever an issue with the quality of the item upon delivery, we encourage you to contact us promptly so we can make it right.
What to do next:
- Check your USDA hardiness zone to understand your typical last frost date.
- Create a "wish list" of colors and shapes before the peak shopping season starts.
- Place your order in mid-winter to ensure the best selection.
- Watch your email for a shipping confirmation as spring approaches.
What to Do After Your Tubers Arrive
Because you often buy tubers before the soil is warm enough for planting, there is usually a short waiting period once the package arrives at your door. Handling this time correctly is just as important as the purchase itself.
When your package arrives, open it immediately. It is important to let the tubers breathe and to check their condition. Healthy tubers should feel firm, much like a fresh potato. If you see a little bit of surface mold, don't worry—this is common and can usually be wiped off.
Short-Term Storage
If the soil is still too cold to plant (dahlias prefer soil that is at least 60°F), you will need to store the tubers for a short time. Keep them in a cool, dark, and dry place. A basement or a cool closet is usually perfect. Keep them in the packing material they arrived in, such as wood shavings or peat moss, to maintain a consistent moisture level. Avoid areas that are prone to freezing or areas with high humidity, like a laundry room, which could encourage rot.
Monitoring Your Tubers
Check on your stored tubers once a week. If they look like they are starting to shrivel, you can give them a very light mist of water. However, the most common mistake is over-watering before they are in the ground. Dahlias are remarkably resilient; they are designed to store energy and moisture within the tuber, so they don't need much help while they are waiting to be planted.
Realistic Expectations for Your Purchase
Gardening is a partnership with nature, and while we provide high-quality tubers, local conditions play a large role in the final result. Factors like your soil type, how much sun the spot receives, and the timing of spring rains will all influence when your dahlias begin to bloom.
Most dahlias take about 90 to 120 days from planting to reach their full flowering potential. If you buy your tubers early and plant them as soon as the soil is warm, you can usually expect blooms to start in mid-to-late July and continue all the way until the first frost of autumn.
It is also helpful to remember that dahlias require patience. They spend the first several weeks after planting developing a strong root system underground. You might not see much action above the soil for a while, but this wait is worthwhile. Once the plants take off, they grow incredibly fast, often adding several inches of height each week during the heat of summer.
Buying for Specific Garden Needs
When you are deciding which tubers to buy, think about the specific "job" you want the flowers to do in your yard. Matching the variety to your space is a simple rule that leads to better results.
- For Cutting Gardens: Look for "decorative" or "cactus" types with long, sturdy stems. These are bred to hold up well in vases and provide a constant supply of bouquets.
- For Containers: If you have a small patio, look for "border" or "gallery" dahlias. These stay naturally compact (usually under 2 feet) and don't require the heavy staking that larger varieties need.
- For Visual Impact: "Dinnerplate dahlias" are the showstoppers. Their blooms can reach 8 to 10 inches across. These are best planted in the middle or back of a garden bed where they have room to grow tall.
By buying your tubers based on these categories, you ensure that you aren't just getting a pretty flower, but a plant that actually fits your lifestyle and garden space.

FAQ
Is it too early to buy dahlia tubers in January?
It is not too early to place your order, but it is too early for delivery in most regions. Buying in January ensures that the varieties you want are reserved for you before they sell out. We will hold your order in our climate-controlled facility and ship it to you when the weather in your area is safe for planting.
Why are some dahlia varieties sold out by March?
Dahlia tubers are a seasonal agricultural product with a limited supply each year. Popular or trendy varieties often have a high demand among home gardeners and floral designers. Once the stock harvested in the fall is spoken for, we cannot get more until the following year's harvest, which is why early ordering is so beneficial.
Can I buy dahlia tubers in the summer?
While you may find some tubers available in early summer, the selection will be very limited and the planting window will be short. Dahlias need a long growing season (90–120 days) to bloom properly. Buying in the winter or early spring is the best way to ensure your plants have enough time to mature and flower before the first frost of autumn.
What should I do if my tubers arrive but it is still snowing outside?
Do not plant them in the ground yet. Instead, keep the tubers in their original packaging and store them in a cool, dark, and dry location, such as a basement or unheated closet. Check them once a week to ensure they stay firm, and wait to plant until the soil in your garden has warmed to about 60°F and all danger of frost has passed.
