These spectacular flowers offer an incredible range of colors and shapes, making them a favorite for both new and experienced gardeners. At Longfield Gardens, we see firsthand how much joy these dinnerplate dahlias bring to summer and fall landscapes. Whether you want soft pastels for a cutting garden or bold, bright colors to line a walkway, timing your purchase is the first step toward success. (longfield-gardens.com)
Understanding when to shop for dahlias ensures you get the best selection of varieties before they sell out. This post covers the ideal months for ordering, how shipping windows work, and how to coordinate your purchase with your local planting weather. This guide is for any gardener who wants to transition from dreaming about dahlias to actually growing them. Choosing the right moment to buy is just as important as choosing the right spot to plant. (longfield-gardens.com)
The Best Time to Order Dahlia Tubers
If you want the widest selection of colors and flower forms, the best time to buy is during the late fall and early winter. Most gardeners start browsing catalogs and websites in December and January. While you won't be planting for several months, this "pre-order" window is when the inventory is most complete. (longfield-gardens.com)
Dahlias have surged in popularity over the last few years. Highly sought-after varieties, such as 'Café au Lait' or specific dark-foliage types, often sell out shortly after they are listed. By placing an order early in the winter, you secure your favorites while they are still in stock. We keep our online shop updated so you can see which varieties are available for the upcoming spring season. (longfield-gardens.com)
Ordering early does not mean you have to worry about immediate care. When you purchase in the winter, we hold your order in our climate-controlled facility in New Jersey. We wait to ship the tubers until the weather is safe for transit and the timing is right for planting in your specific area. This system allows you to plan your garden layout in the quiet winter months and receive your plants exactly when you need them. (longfield-gardens.com)
Why Early Ordering Matters
- Availability: You get the first pick of rare or trendy varieties.
- Planning: You can map out your garden beds and color schemes well in advance.
- Peace of Mind: Your order is reserved, so you don't have to scramble for plants in the spring. (longfield-gardens.com)
Key Takeaway: Shop for dahlia tubers in December or January to ensure you get the specific varieties you want for your summer garden. (longfield-gardens.com)
Understanding Shipping Windows and USDA Zones
When you buy dahlia plants online, the shipping date is determined by your location. Dahlias are tropical plants that are sensitive to freezing temperatures. We use the USDA Plant Hardiness Zone Map to decide the safest time to send your order. This ensures the tubers do not freeze while they are in the back of a delivery truck. (longfield-gardens.com)
Most shipping begins in March for warmer southern zones and continues through May for northern regions. We aim to have your tubers arrive about two weeks before the ideal planting time in your area. This gives you a small window to inspect your order and prepare your garden soil. (longfield-gardens.com)
We ship to the 48 contiguous United States. Because of agricultural regulations, we do not ship to Hawaii, Alaska, or international locations. Once your order leaves our facility, you will receive a tracking number so you can follow its journey to your doorstep. It is important to note that a "label created" notification means the process has started, but the actual shipping confirmation indicates the carrier has picked up your box. For the full schedule, see our Shipping Information. (longfield-gardens.com)
General Shipping Timeline
- Zones 8-10: Typically ship in March.
- Zones 6-7: Typically ship in April.
- Zones 3-5: Typically ship in late April or early May. (longfield-gardens.com)
Buying Dahlias in the Spring
If you miss the early winter ordering window, you can still buy dahlia tubers throughout the spring months. Many gardeners wait until they are actually ready to dig in the dirt before they start shopping. This approach works well if you are flexible about which varieties you grow, and the Dahlia Collections page is a great place to browse curated options. (longfield-gardens.com)
By late April or May, some of the most famous varieties may be sold out, but there are always beautiful options available. Spring shopping is perfect for filling unexpected gaps in your flower beds or for trying a new color on a whim. The tubers you buy in late spring are ready to go into the ground as soon as they arrive. (longfield-gardens.com)
Keep in mind that dahlias need a long growing season to reach their full potential. While you can plant them as late as mid-June in many parts of the country, planting earlier in the spring gives the roots more time to establish. A strong root system leads to more flowers in late summer. (longfield-gardens.com)
What to do next: If you are buying in late spring, check for varieties that have a shorter "days to bloom" count to ensure you get plenty of flowers before the first frost.
Coordinating Your Purchase with Local Weather
Buying the plants is the first step, but knowing when to put them in the ground is just as vital. Dahlias love warmth. They should not be planted until the soil has warmed up to about 60°F and the danger of frost has completely passed. If you plant too early in cold, wet soil, the tubers may rot before they have a chance to grow. Our How to Plant Dahlias guide shows the basic timing and planting steps. (longfield-gardens.com)
A good rule of thumb is to plant your dahlias at the same time you would plant tomatoes or peppers. These "warm-weather" plants share similar needs. If the nights are still chilly and you are still wearing a heavy coat outside, it is likely too early for your dahlias. (longfield-gardens.com)
Watching your local weather forecast is better than following a strict calendar date. Every spring is different. Some years allow for early May planting, while other years require waiting until June. Being patient for those few extra degrees of soil warmth pays off with faster growth and healthier plants. (longfield-gardens.com)
Simple Planting Checks
- Soil Temp: Use a soil thermometer to check for 60°F.
- Soil Texture: The ground should be moist but not soggy.
- Frost Forecast: Ensure no freezing temperatures are predicted for at least 10 days. (longfield-gardens.com)
Choosing Which Dahlias to Buy
When you are ready to buy, the sheer number of choices can be surprising. Dahlias come in many different sizes and shapes. Knowing the basic categories will help you buy the right plants for your specific garden goals, and the Dahlia Forms for Garden and Vase guide shows how the forms differ. (longfield-gardens.com)
Dinnerplate Dahlias
These are the giants of the dahlia world. The flowers can reach 8 to 10 inches in diameter. They are stunning in the back of a flower border or as a focal point in a large garden. Because the blooms are so heavy, these plants usually need sturdy staking to keep them upright, which is why so many gardeners start with Dinnerplate Dahlias. (longfield-gardens.com)
Decorative Dahlias
This is the most common category. These flowers have a classic look with broad, flat-tipped petals. They come in a massive range of colors and are excellent for cutting. They usually grow to a medium height, making them versatile for almost any garden spot, and you can browse Decorative Dahlias if you want a reliable all-around choice. (longfield-gardens.com)
Cactus and Semi-Cactus Dahlias
These varieties have long, pointed petals that curve backward. This gives the flowers a spiky, starburst appearance. They add a unique texture to bouquets and are known for being quite resilient in the garden. If that look appeals to you, take a look at Cactus & Semi-Cactus Dahlias. (longfield-gardens.com)
Border and Gallery Dahlias
If you have a small yard or want to grow flowers in containers, these are the plants to buy. They stay compact, usually reaching only 12 to 18 inches tall. They don't require staking and produce a high volume of small, cheerful blooms all season long. Border Dahlias are especially handy when you want big color in a smaller space. (longfield-gardens.com)
Ball and Pompon Dahlias
These flowers are perfectly round and look like little honeycombs. The petals are tightly furled. Because the blooms are so symmetrical and the stems are usually very stiff, Ball Dahlias are a favorite for professional florists and home arrangers alike. (longfield-gardens.com)
What to Look for When Your Order Arrives
When your box from Longfield Gardens arrives, it is a good idea to open it immediately. You want to see healthy, firm tubers. They might look like a small bunch of potatoes or a single long root. Don't worry if they look a little dry or dusty; that is normal for dormant tubers. Our All About Dahlias guide explains what makes a good tuber and how to get started. (longfield-gardens.com)
The most important part of the tuber is the "eye." The eye is a small bump or a sprout located near the neck where the tuber connects to the old stem. This is where the new growth will come from. Sometimes the eyes are very easy to see, and other times they are just tiny green or pink points. If you don't see an eye right away, don't worry. Once the tuber is exposed to warmth and light, the eye will become more prominent. (longfield-gardens.com)
If you aren't ready to plant your dahlias because the soil is still too cold, you can store them for a short time. Keep them in a cool, dark, and dry place like a basement or a garage. Leave them in the packing material they arrived in to keep them from drying out completely. (longfield-gardens.com)
Immediate Steps After Delivery
- Unbox: Take the tubers out of the shipping box to let them breathe.
- Inspect: Check for firm texture and visible eyes.
- Store: Keep in a cool (40–50°F) spot if planting is more than a week away.
- Prepare: Gather your stakes, compost, and garden tools. (longfield-gardens.com)

Tips for Successful Buying and Planting
To get the most out of your purchase, keep these simple rules in mind. These steps help ensure that the money and time you spend on your dahlias result in a beautiful display, and our How to Plant and Grow Dahlias for a Spectacular Garden guide offers a fuller walkthrough. (longfield-gardens.com)
Right Plant, Right Place
Before you buy, look at your garden. Dahlias need at least six to eight hours of direct sunlight every day. If your yard is very shady, the plants will grow tall and lanky but won't produce many flowers. Choose a spot with well-draining soil. "Drainage" simply refers to how fast water moves through the ground. If you have a spot where puddles stand for hours after a rain, it is not the right place for dahlias. How Dahlias Grow explains why that matters. (longfield-gardens.com)
Space Them Out
It is tempting to crowd plants together for a full look, but dahlias need room to breathe. Most varieties should be spaced about 18 to 24 inches apart. Good airflow between the plants helps prevent common leaf issues like powdery mildew. If you are planting smaller border varieties, you can place them a bit closer, about 12 inches apart. (longfield-gardens.com)
Wait to Water
One of the most common mistakes is watering the tubers too much right after planting. Until you see green sprouts coming out of the ground, the tuber doesn't have roots to take up water. The moisture already inside the tuber is enough to get it started. Once the plant is a few inches tall, you can begin a regular watering schedule. (longfield-gardens.com)
Deep, Not Constant
When you do start watering, aim for deep soaking rather than light sprinkles. This encourages the roots to grow deep into the soil where it stays cooler and more consistent. If the top inch of soil feels dry, it is usually time to water. (longfield-gardens.com)
Key Takeaway: Success with dahlias starts with buying high-quality tubers and waiting for the soil to warm up before planting them.
Handling Common Purchasing Questions
Many people wonder if they should buy "started" plants in pots or dormant tubers. Most of the dahlias we sell are dormant tubers. These are easier to ship and generally more affordable. Tubers also have a lot of stored energy, which allows them to grow very quickly once they hit the warm spring soil. (longfield-gardens.com)
Another common question is about the size of the tuber. Some varieties naturally produce huge, thick tubers, while others produce small, thin ones. The size of the tuber does not determine the size of the plant or the flower. As long as there is a healthy eye on the tuber, it has everything it needs to grow into a spectacular plant. (longfield-gardens.com)
You may also see "mixes" for sale. These are a great choice if you want a variety of colors without having to pick out each one individually. Our mixes are carefully selected to ensure the colors look beautiful together in the garden and in a vase. (longfield-gardens.com)
Planning for Continuous Blooms
If you want flowers from mid-summer all the way until the first frost, consider buying a mix of varieties with different bloom times. Some dahlias start flowering earlier in the season, while the large dinnerplate types often take a bit longer to reach their peak. (longfield-gardens.com)
By mixing early, mid, and late-season bloomers, you ensure your garden is never without color. This is especially helpful for people who love to make fresh flower arrangements. Having a constant supply of blooms means you can always have a fresh bouquet on your kitchen table, and the Dahlia Forms for Garden and Vase guide can help you choose forms you love. (longfield-gardens.com)
The Joy of the Harvest
When you buy dahlias, you aren't just buying a plant; you are buying months of beauty. Dahlias are some of the most productive flowers in the garden. The more you cut the flowers, the more the plant will produce. This "cut and come again" nature makes them incredibly rewarding. (longfield-gardens.com)
When the blooms are fully open, snip them early in the morning when the temperature is cool. Place them immediately in a bucket of water. These flowers will brighten up your home and make wonderful gifts for friends and neighbors. Growing dahlias is a great way to share the beauty of your garden with the people around you. (longfield-gardens.com)

FAQ
When is the earliest I can buy dahlia tubers?
You can usually start pre-ordering dahlia tubers in late fall or early winter, typically starting in December or January. This is the best time to shop if you want to secure popular or rare varieties before they sell out. We hold these orders and ship them to you in the spring when the weather is safe for planting in your zone. (longfield-gardens.com)
Why can’t I buy and have dahlias shipped in the middle of winter?
Dahlias are tropical tubers that are very sensitive to freezing temperatures. If we shipped them during the coldest months of winter, the tubers could freeze and die during transit in delivery trucks. We monitor the weather and your USDA zone to ensure the plants arrive healthy and ready to grow. (longfield-gardens.com)
Is it better to buy tubers or started plants?
Buying dormant tubers is often the best choice for home gardeners because they are easy to ship, cost-effective, and carry a lot of stored energy for growth. While you can sometimes find potted dahlias at local nurseries in late spring, buying tubers online gives you access to a much wider variety of shapes, sizes, and colors that aren't usually available in garden centers. (longfield-gardens.com)
What should I do if the variety I want to buy is sold out?
If a specific dahlia is sold out, we recommend checking for varieties with similar colors or flower forms. Many dahlias have close "relatives" that look very similar in a garden setting. You can also browse our Top-Rated Dahlias to find popular alternatives for the following season. (longfield-gardens.com)
