Plant season is coming. And every year, millions of people walk into a garden center, spend $6 on a tomato seedling they could have grown for pennies, and go home happy. That transaction happens billions of times every spring. Somebody is on the other side of it making money.
That somebody could be you.
This one works whether you've been gardening for years or you've never grown anything in your life. If you already garden, you're probably starting seeds anyway — this is just doing a little more of what you're already doing and selling the extras. If you're new, starter plants are one of the most forgiving entry points into both gardening and selling because the product sells itself, the startup cost is low, and your customers are motivated. Nobody haggles over a $4 tomato plant.
Here's how it actually works.
What to Grow
Not everything is worth your time and space. Stick to what people actually buy every spring.
Vegetables and herbs are your bread and butter. Tomatoes, peppers, basil, cucumbers, zucchini, and herbs like rosemary, mint, and parsley move fast because people want to grow food but don't want to start from seed. They'll pay $3–6 per plant without blinking.
Flowers are close behind. Marigolds, zinnias, petunias, and snapdragons are popular, easy to grow in volume, and sell well to people who want color in their yard without the work of starting from seed.
Perennials are a longer game but worth it. Hostas, coneflowers, black-eyed Susans, once you have established plants you can divide them every year and sell the divisions for free inventory forever.
Leave alone for now: anything slow, fussy, or that requires serious knowledge to grow well. You want things that go from seed to sellable in 4–8 weeks.
What You Actually Need to Start
This is not an expensive startup. Most of what you need you either already have or can get for very little.
Seeds — before you spend anything, check your local library. A lot of them have seed libraries where you can pull seeds for free. Seriously, call before you buy. If yours doesn't have one, seed packets run $2–4 and a single packet can produce 40–100 plants.
Light — this is the one thing you can't skip. If you already have a lamp, you might just need these bulbs and you're good to go. If you want a dedicated setup, this grow light is what I use — my tomatoes already have buds on them so I can tell you firsthand it works.
Something to grow in — this starter tray is what I've used in past seasons with good results. Simple and does the job. This year I'm stepping it up and trying this full kit that comes with everything you need in one — I'll report back on how it goes.
Containers for selling — once seedlings are ready to sell you need something to put them in. Solo cups with a hole poked in the bottom work fine. So do yogurt containers or any small pots you already have.
That's it. Total investment under $50 if you're starting from nothing — and potentially much less if your library has seeds.
Where to Sell
Facebook Marketplace is your first stop. List locally, people pick up, you keep every dollar. "Starter plants — tomatoes, peppers, herbs, ready mid-May" with a photo of your trays will get messages.
Farmers markets are the next level. A table fee is usually $15–30 for the day and you can move a lot of volume in a few hours if you're set up well.
Nextdoor and neighborhood Facebook groups; post when you're ready and let the neighborhood come to you. No fees, no setup, cash at the door.
Word of mouth, tell one person you have plants for sale. By the following weekend three more people will ask you.
The Math
One packet of tomato seeds: $3. Yields 40 healthy seedlings. Sell at $4 each. That's $160 from a $3 investment and a few weeks of watering.
Do that with five varieties across vegetables and herbs, spend $20 on seeds total, and a realistic spring season nets $400–800 without a storefront, a boss, or a business license in most states.
What to Know Before You Start
Timing is everything. You need to know your last frost date and count backward. Most vegetable seedlings need 6–8 weeks indoors before they're ready to sell. Start too late and you miss the window. Search "last frost date" plus your zip code — it takes 30 seconds.
Don't overgrow your space. It sounds fun to start 200 plants until they're all on your kitchen table fighting for light and you're watering twice a day. Start with what you can realistically manage and scale next year.
Check local rules. Most areas allow small plant sales without a license, but if you're going to a farmers market they may require a basic vendor registration. It's usually simple and cheap.
Is This Worth It?
Yes, especially if you already garden. The margin on plants is genuinely one of the best in any physical product hustle. Your cost is seeds, soil, and time. Your selling price is set by what the garden center charges, and people will pay it because buying local feels good and supporting a neighbor feels better.
If you've never gardened before, this is still worth trying. Start small. Grow one flat of tomatoes. See what happens. The worst case is you end up with a lot of tomato plants for your own garden. The best case is you just found something you'll do every spring from here on out.
The season is coming. Might as well be in it.
A Few Things to Check Before You Start Selling
This is the part most people skip and probably shouldn't.
Nursery licenses — some states require a nursery license once you start selling plants, even small scale. It's usually inexpensive and straightforward but you do need to check. Look up your state's department of agriculture website and search nursery license requirements. It takes ten minutes and saves you a headache later.
Invasive species — this one surprises people. Some plants are actually illegal to sell in certain states because they're considered invasive. Before you grow something to sell, do a quick search for your state's invasive species list. Your department of agriculture website will have it.
Farmers market rules — don't assume you can just show up. Most markets require vendor registration and some require proof that you grew what you're selling. A few require a basic nursery permit even for small sellers. Email the market organizer before you commit to a table fee.
HOA rules — if you live in an HOA, check your agreement before you start selling from your home. Some have restrictions on home-based sales. Better to know upfront.
Taxes — once you're making money it's income, even if it came from tomato plants in your kitchen. Keep a simple record of what you spend and what you make. Nothing fancy, even a notes app works. You'll thank yourself later.
None of this is meant to scare you off. Most people selling a flat or two of tomatoes at a neighborhood farmers market are not going to run into any of these. But if you're going to do this seriously and build it into something real, knowing the rules is part of doing it right.
