Seedlings and transplants are one of the most profitable spring products at farmers markets because they cost almost nothing to produce (seeds + soil + water + time), sell for $2 to $6 each, and have a built-in selling season (March through June) when demand far outpaces supply. Unlike food products, seedlings require no cottage food permit, no health department approval, and no food safety compliance. They are agricultural products — plants — and are regulated (minimally) under your state's nursery or plant dealer laws, which for small-scale sellers usually require nothing more than a simple registration or no registration at all.
The short version: A tray of 72 seedlings costs $5 to $10 to produce (seeds, soil, containers, water) and sells for $144 to $432 ($2 to $6 per plant). Margins are 90 to 97%. The spring selling season (March through June depending on your zone) creates intense demand from home gardeners who missed their seed starting window or want established plants. You need a sunny window, grow lights ($30 to $80), seed starting trays ($10 to $20), potting soil ($15 per bag), and seeds ($1 to $3 per packet). Start seedlings 6 to 8 weeks before your USDA hardiness zone's last frost date. Sell at your farmers market booth alongside your food products. If you also sell food through a Homegrown storefront, add seedlings to your ordering page for spring pre-orders — gardeners will pre-order their tomato transplants alongside their sourdough and jam.
| Expense | Cost Per 72-Cell Tray |
|---|---|
| Seeds (1 packet per variety) | $0.50-$1.50 |
| Seed starting mix (enough for 1 tray) | $2-$3 |
| 72-cell tray + humidity dome | $2-$4 |
| Water and electricity (grow light) | $0.50-$1.00 |
| Total per tray | $5-$9.50 |
| Cost per seedling | $0.07-$0.13 |
At a selling price of $2 to $6 per seedling, the margin is 95 to 98%. Even at the cheapest price ($2 per 4-pack), a single 72-cell tray generates $36 in revenue from $5 to $10 in inputs.
Most home gardeners know they should start seeds indoors in February or March but never get around to it. By April, they need transplants, and the selection at big box stores is limited to a few generic varieties. A farmers market vendor offering heirloom tomatoes, unique pepper varieties, and herb starts fills a gap that Home Depot cannot.
A gardener who buys your tomato transplants in April comes back for pepper starts in May, herb starts in June, and fall crop starts (broccoli, kale, cabbage) in August. Seedling customers visit multiple times per season, and each visit, they also buy your food products.
Seedlings are plants, not food. No cottage food permit, no health department inspection, no food handler's certificate. For context on what food products DO require, Cornell Small Farms' income tax guide covers the food side — seedlings avoid all of it. The regulatory burden is close to zero for small-scale sellers. Most states have a nursery licensing threshold (often $500 to $5,000 in annual plant sales) below which no license is required. Check your state's nursery registration rules if you plan to sell more than a few hundred dollars per year.
Start with tomatoes, peppers, and herbs. These three categories cover 80% of spring seedling demand.
| Item | Cost | Purpose |
|---|---|---|
| Grow light (LED shop light or T5 fluorescent) | $30-$80 | Light for indoor growing |
| Timer for grow light | $10 | 14-16 hours of light per day |
| 72-cell seed starting trays (10 trays) | $20-$40 | Growing containers |
| Humidity domes (10) | $15-$25 | Moisture retention during germination |
| Heat mats (optional) | $20-$40 | Faster germination for heat-loving crops |
| Seed starting mix (2-3 bags) | $15-$25 | Growing medium |
| Seeds (10-15 varieties) | $15-$40 | Plant varieties |
| Total startup | $125-$250 |
This equipment pays for itself after selling 50 to 80 seedlings ($100 to $400 in revenue).
| Weeks Before Last Frost | Action |
|---|---|
| 8-10 weeks | Start tomatoes and peppers (slow growers) |
| 6-8 weeks | Start herbs, flowers, and squash |
| 4-6 weeks | Start lettuce, greens, and fast growers |
| 2 weeks | Harden off all seedlings (move outdoors gradually) |
| 0 (last frost date) | Begin selling at market |
| Product | Cost | Price | Margin |
|---|---|---|---|
| Individual seedling (4" pot) | $0.30-$0.60 | $3-$6 | 80-95% |
| 4-pack (same variety) | $0.30-$0.50 | $4-$8 | 85-94% |
| Herb garden set (4 herbs) | $0.80-$1.20 | $10-$14 | 88-92% |
| "Salsa garden" set (tomato + pepper + cilantro) | $0.60-$1.00 | $10-$15 | 90-94% |
Themed sets (herb garden, salsa garden, pizza garden, tea garden) sell at a premium because they solve a decision problem for the customer. Instead of picking individual plants, they buy a curated collection.
If you sell food products alongside seedlings, pair them: "Buy the basil plant and the pesto you will make with it" (basil start + bread = a natural upsell). Seedling customers spend an average of $5 to $15 more on food products per visit than non-seedling customers because they are already in buying mode.
For pre-ordering seedlings online alongside your food products, your Homegrown storefront lets customers reserve specific varieties before they sell out at the market.
Most states have a threshold below which no nursery license is required — often $500 to $5,000 in annual plant sales. Small-scale sellers at farmers markets typically fall below this threshold. If you sell more than your state's threshold, a nursery dealer license is usually simple and inexpensive ($25 to $100 per year). Check your state's Department of Agriculture for specific rules.
The 4 to 6 weeks after your last frost date is peak selling season. In most of the US (USDA zones 5 to 8), this means mid-April through early June. A second, smaller selling season exists in August through September for fall crop starts (broccoli, kale, cabbage).
A 4-foot by 2-foot grow light shelf holds 4 to 6 standard 72-cell trays (288 to 432 seedlings). At $3 per seedling, that is $864 to $1,296 in revenue from an 8 square foot space. Most home growers start with 2 to 4 trays (144 to 288 seedlings) for their first season.
Spring (March to June) and early fall (August to September) are the natural selling seasons. During summer and winter, demand drops significantly because it is not planting season. Some vendors grow microgreens or indoor herb starts during the off-season to maintain year-round plant sales.
Unsold seedlings can be planted in your own garden, donated to a community garden, or potted up to a larger size and sold the following week at a higher price. Unlike food, unsold seedlings do not spoil — they keep growing. A tomato seedling that does not sell in a 4-inch pot becomes a larger, more valuable plant in a 6-inch pot the next week.
Label every seedling with the variety name at minimum. A plant stake saying "Cherokee Purple Tomato" takes 5 seconds to write and significantly increases the chance of a sale. Better labels include variety name, days to maturity, plant size, sun requirements, and one growing tip. The label is your sales tool — a customer who knows the plant is "Cherokee Purple — heirloom, 80 days, 6 ft vine, best slicer" is more likely to buy than one looking at an unlabeled green plant.
Use shallow trays or flats that hold the cell packs securely. Line your vehicle with a tarp or plastic sheet (for water spillage). Drive slowly — seedlings are top-heavy and tip easily during turns. If transporting in an open truck bed, cover with a shade cloth to prevent wind damage and sunburn. Arrive 30 minutes early to let plants recover from the drive before customers see them.
If your last frost date is May 1 and you start seeds April 1, your seedlings will be tiny, leggy starters when competitors are selling robust 6-week-old transplants. Start tomatoes and peppers 8 to 10 weeks before last frost. Mark the dates on your calendar in January.
Offering 30 tomato varieties sounds impressive but confuses customers and splits your inventory. Start with 5 to 8 varieties of your top seller (tomatoes) and 3 to 4 of each secondary crop. Focused selection sells better than overwhelming variety.
Wilted seedlings do not sell. Water thoroughly the morning of the market. Bring a spray bottle for mid-market refreshing. If your market is in full sun and runs 4+ hours, some plants will need a mid-day drink. Crisp, green, upright plants outsell droopy ones every time.
Seedlings at $1 per plant look cheap and unserious. Customers at farmers markets expect to pay $3 to $6 for a quality transplant. A $2 tomato seedling in a 2-inch cell sends the message "this is a leftover from my garden." A $4 tomato in a 4-inch pot with a variety label says "this is a professional plant worth planting." Price to reflect quality, not cost.
A table of green plants without labels or pricing looks like a yard sale, not a professional nursery stand. Label every variety. Post a large sign with your business name and "Locally Grown Seedlings — Tomatoes, Peppers, Herbs." Include a price list visible from 10 feet away.
Seedlings are impulse purchases for many market visitors who came for vegetables or bread. Position your plants near the aisle where foot traffic is heaviest. Use bright, blooming flowers as eye-catchers at the front corners of your display — they draw people in, and once they stop, they browse the tomatoes and herbs behind.
Unsold seedlings can be planted in your own garden, donated to a community garden, or potted up to a larger size and sold the following week at a higher price.

Label every seedling with the variety name. At minimum: "Cherokee Purple Tomato" on a plant stake. Better: a tag with variety name, days to maturity, plant size, and growing tips. The label is your sales tool — a customer who knows a tomato is "Cherokee Purple — heirloom, 80 days, 6 ft vine, best slicer" is more likely to buy than one looking at an unlabeled green plant.
