Introduction
There is a unique kind of magic that happens in the garden during late summer when dahlias reach their peak. These spectacular blooms offer an incredible variety of colors and shapes, from the massive dinnerplate varieties to the perfectly symmetrical pompons. One of the most rewarding aspects of growing these flowers is discovering that they are the gift that keeps on giving. Beneath the soil, a single tuber planted in the spring transforms into a generous clump by autumn, providing you with several new plants for the following year.
At Longfield Gardens, we believe that every gardener can enjoy the beauty of dahlias, and selling your extra tubers is a wonderful way to share that joy with others. Whether you want to fund your own gardening hobby or start a small side business, the process is straightforward and deeply satisfying. This guide will walk you through the essential steps of harvesting, dividing, and marketing your tubers so you can turn your garden's abundance into a successful sale.
By following a few simple steps for care and organization, you can transition from a casual hobbyist to a confident seller. If you start with a few high-quality dahlia varieties, you can quickly expand your inventory without spending more money. Growing and selling dahlia tubers is not just a way to earn extra money; it is a way to build a community of fellow flower lovers. With the right approach to quality and customer service, you can create a sustainable cycle that keeps your garden—and your wallet—blooming year after year.
The Natural Wealth of Dahlia Tubers
Understanding the biology of a dahlia is the first step toward selling them successfully. When you plant a dahlia tuber in the spring, it uses its stored energy to send up a sprout. As the plant grows and photosynthesizes throughout the summer, it doesn't just produce flowers. It also focuses on storing energy underground. By the end of the growing season, that original "mother" tuber has typically produced a cluster of three to ten new tubers.
This natural multiplication makes dahlias an excellent investment for any gardener. If you start with a few high-quality varieties, you can quickly expand your inventory without spending more money. This "underground gold" allows you to keep what you need for your own display while having plenty of stock left over to sell.
For the best results, start with healthy, vibrant plants. We work with trusted growers to ensure that the stock you begin with is strong and true to variety. When your customers buy from you, they are looking for that same reliability. Selling tubers is about more than just the physical product; it is about providing the potential for a beautiful garden.
Timing Your Harvest for Maximum Quality
The health of your tubers depends heavily on when you take them out of the ground. In most climates, you want to leave the tubers in the soil as long as possible so they can fully mature. The longer they stay in the ground, the more energy they store and the better they will handle winter storage.
A common rule of thumb is to wait for the first "killing frost." If you want a quick climate reference, the hardiness zone map can help you plan. This is the frost that turns the foliage black and signals the plant to go dormant. If you live in a region that does not experience frost, you can simply wait until the plants begin to yellow and die back naturally in late autumn. Once the top growth is dead, cut the stalks down to about four to six inches above the soil line.
Letting the tubers sit in the ground for about a week after cutting the stalks is a helpful step. This short "curing" period allows the skins of the tubers to toughen up slightly, which makes them more durable during the digging and cleaning process.
What to do next:
- Watch your local weather forecast for the first frost date.
- Prepare your tools, including a sturdy pitchfork and labeling materials.
- Cut back dahlia stalks once they turn brown or black.
- Wait 5 to 7 days before digging to allow the tubers to cure.
Digging and Cleaning Your Stock
Digging up dahlia tubers is a task that requires a gentle touch. Using a garden fork or pitchfork is generally better than using a shovel. Shovels have sharp edges that can easily slice through a tuber, while a fork allows you to lift the entire clump from underneath.
Start by inserting your fork into the soil about 12 inches away from the main stalk. Gently pry upward, working your way around the entire plant. You want to lift the whole clump out of the ground without snapping the narrow "necks" that connect the tubers to the main stem. The neck is the most fragile part of the tuber, and if it breaks, the tuber will not be able to sprout.
Once the clump is out of the ground, gently shake off the excess soil. You can use a soft stream of water from a garden hose to wash away the remaining dirt. This makes it much easier to see where you need to make your cuts when you begin dividing. Avoid using high-pressure settings, as you don't want to nick the skin.
The Art of Dividing Tubers
Dividing tubers is the most technical part of the process, but it becomes quite simple once you know what to look for. Each individual tuber must have an "eye" to grow a new plant next year. An eye is a small bump or growth point, similar to the eye on a potato, and it is located on the "crown" of the clump. The crown is the area where the tuber neck meets the main stalk.
It is often easiest to divide tubers in the fall right after cleaning, as the plant tissue is softer and easier to cut. However, some gardeners prefer to wait until spring when the eyes are more prominent and easier to see. If you are selling your tubers, dividing in the fall allows you to take an accurate inventory of your stock early on.
To divide, use a sharp, clean pair of garden snips or a small knife. First, cut the clump into smaller, manageable sections. Then, carefully isolate individual tubers, ensuring each one has a piece of the crown and at least one visible eye. Discard any tubers that are shriveled, diseased, or broken at the neck.
Key Takeaway: A viable dahlia tuber must have three things: a healthy body for food storage, a solid neck, and a piece of the crown with a visible eye. Without all three, the tuber will not grow.
Proper Labeling and Inventory Management
If there is one rule for selling dahlia tubers, it is this: never lose track of your varieties. A customer who buys a "Cafe au Lait" dahlia expects that specific bloom, not a surprise pink pompon. Labeling is the foundation of a high-trust gardening business.
There are several ways to keep your tubers organized. Many sellers use an indelible garden marker to write the variety name directly on the skin of the tuber once it is dry. This is the most foolproof method because tags can fall off or become misplaced. You can also use small mesh bags with waterproof tags for each variety.
As you divide and label, keep a detailed inventory. Use a simple spreadsheet or a notebook to record how many viable tubers you have of each variety. This will help you know exactly what you have available to sell when you open your shop.
Storing Tubers for Winter
Before you can sell your tubers, they must survive the winter in prime condition. The goal of storage is to keep the tubers dormant, cool, and hydrated without letting them rot or freeze. Ideal storage temperatures are between 40°F and 50°F.
Most sellers store their tubers in a medium that helps regulate moisture. Popular choices include:
- Pine shavings: These provide good airflow and are very affordable.
- Vermiculite: This holds moisture well and is excellent for drier climates.
- Peat moss: A traditional choice, though it can be dusty to work with.
Place a layer of your chosen medium in a plastic bin or a cardboard box lined with newspaper. Lay your tubers out so they are not touching, then cover them with more medium. If you use plastic bins, do not snap the lids on tight; leave them slightly ajar to allow for some air exchange. Check your tubers once a month throughout the winter. If they look shriveled, lightly mist the storage medium with water. If you see any soft spots or signs of rot, remove the affected tubers immediately to prevent the problem from spreading.

Setting Your Prices
Pricing your dahlia tubers requires a balance between being competitive and valuing your time and effort. Research what other sellers are charging for similar varieties. Standard, common varieties usually sell for less, while rare or highly sought-after dahlias can command a premium price.
When setting your price, consider the following factors:
- Variety Rarity: Is this a dahlia that is hard to find?
- Tuber Quality: Are your tubers large, firm, and healthy?
- Supplies: Factor in the cost of your storage medium, labels, and packaging.
- Market Demand: Some colors and shapes become very popular due to wedding or floral trends.
Most home-grown tubers sell in the range of $5.00 to $20.00 each. Offering "mixed varieties" or grab bags of mixed varieties can also be a great way to sell through your inventory quickly.
Photography and Marketing
Because you are usually selling tubers in the winter or spring when the plants are dormant, your photos are your most important sales tool. People buy dahlia blooms based on the beauty of the flower, so you need high-quality images of your blooms from the previous summer.
Take photos of your dahlias throughout the growing season. Capture the flower from the front, the side, and even a shot of the whole plant so customers can see the growth habit. Bright, natural light is best for showing true colors. Avoid using filters that change the appearance of the flower, as accuracy builds trust with your buyers.
Once you have your photos, you can start marketing. Social media is a powerful tool for small-scale sellers. Share photos of your garden in the summer and give "behind-the-scenes" updates as you dig and divide in the fall. This builds excitement and lets people know when your sale will go live.
Where to Sell Your Tubers
There are several ways to reach potential customers, depending on how many tubers you have and how much time you want to spend on the process.
Local Sales
Selling locally is the easiest way to start because it eliminates the need for shipping. You can list your tubers on Facebook Marketplace, in local gardening groups, or on community apps like Nextdoor. Some gardeners even set up a simple stand at the end of their driveway in the spring. Local sales are great for building a community of gardeners in your own neighborhood.
Online Platforms
If you have a larger inventory, online platforms like Etsy or a dedicated website can help you reach a national audience. These platforms handle the payment processing for you, but they do charge fees. If you choose this route, you will need to be prepared for the logistics of shipping across different climate zones.
Flower Subscriptions and Bundles
You can also bundle your tubers with other products. For example, if you sell cut flowers in the summer, you can offer your regular customers a "grow your own" kit in the spring that includes a few of their favorite varieties from your bouquets.
What to do next:
- Organize your summer photos by variety.
- Research local gardening groups online.
- Decide whether you want to sell locally or ship nationally.
- Draft a simple description for each variety you plan to sell.
Handling the Logistics of Shipping
If you decide to sell your tubers to customers outside your local area, our shipping information is a critical part of the job. Dahlia tubers are perishable and sensitive to extreme temperatures. You cannot ship them when there is a risk of them freezing in transit.
Most dahlia sellers open their online shops in mid-winter but do not actually ship the tubers until the spring. This is known as "preselling." You take the orders and payments early, then ship the tubers once the weather warms up in April or May.
When packing for shipment:
- Wrap securely: Use paper bags or plastic bags with a bit of dry peat moss or shavings to protect the tuber.
- Use sturdy boxes: Cardboard boxes are essential to prevent the tubers from being crushed.
- Add instructions: Including a simple care sheet with planting tips is a thoughtful touch that helps your customers succeed.
- Choose a reliable carrier: Use services that provide tracking numbers so both you and the customer can monitor the package.
Providing Excellent Customer Service
The key to a long-term dahlia business is repeat customers. Gardeners love to share their successes, and if your tubers grow into beautiful plants, your customers will come back every year.
Be honest about your stock. If a variety didn't store well and you no longer have enough to fill an order, contact the customer immediately to offer a refund or a substitute. Clear communication is vital. Answering questions about planting depth, sun requirements, and soil drainage shows that you are a knowledgeable and helpful seller.
At Longfield Gardens, we stand behind our 100% Quality Guarantee, and we suggest you do the same. Providing a healthy, viable tuber with a visible eye is the best way to ensure your customers are happy. Remember, gardening should be an enjoyable experience, and your role as a seller is to make that possible for someone else.
Understanding Basic Business Logistics
While selling a few tubers from your driveway is simple, if you plan to grow into a larger operation, there are a few practical things to consider. Every state has different rules regarding the sale of plant material. Some states require a nursery license or a brief inspection to ensure you aren't spreading pests or diseases.
Check with your local Department of Agriculture or University Extension office to see what is required in your area. These steps are usually very straightforward and help maintain the health of the gardening industry. Additionally, keep track of your income and expenses for tax purposes. Even a small hobby business should have basic record-keeping in place.
Managing Realistic Expectations
Selling dahlia tubers is a rewarding venture, but it is important to remember that you are working with nature. Factors like an unusually wet autumn, an unexpected hard freeze, or a storage issue can affect your inventory.
Not every tuber you dig will be sellable. Some may be too small, some may not have a clear eye, and some may simply not make it through the winter. This is a normal part of the process. Experienced sellers usually account for a small percentage of loss when they plan their inventory. By being conservative with your numbers and focusing on quality over quantity, you will set yourself up for a stress-free and successful selling season.
Key Takeaway: Success in selling dahlia tubers comes from a combination of careful summer record-keeping, gentle autumn harvesting, and diligent winter monitoring.

FAQ
When is the best time to start selling my dahlia tubers?
Many sellers open their online shops in January or February to take "pre-orders" while gardeners are planning their spring landscapes. However, the physical shipping of the tubers should wait until the spring when the danger of freezing during transit has passed. If you are selling locally, the best time is typically in late March or April, just as the planting season begins.
How do I know if a dahlia tuber is "good" enough to sell?
A high-quality tuber should be firm to the touch, not shriveled or mushy. It must have an intact neck and a visible "eye" or sprout on the crown. If you are unsure if a tuber will grow, it is better to keep it for your own garden to test rather than selling it to a customer.
Do I need to wash the tubers before I store or sell them?
While some gardeners store their tubers with the soil still attached, most sellers prefer to wash them. Cleaning the tubers makes it much easier to see the eyes for dividing and allows you to inspect the health of the plant tissue. Ensure the tubers are completely dry before putting them into storage to prevent mold.
What should I do if a customer says their tuber didn't grow?
Gardening results can vary based on soil, weather, and planting depth. It is helpful to provide clear planting instructions with every sale to help your customers succeed. If a customer has a problem, listen to their concerns and offer a solution, such as a replacement tuber or store credit, which helps build a positive reputation for your business.
