Every spring, thousands of home gardeners are looking for locally grown, hardened-off seedlings, and they're willing to pay a premium for quality transplants from a trusted farm.
For market gardeners, a well-planned seedling sale can generate $2,000 to $10,000+ in a single weekend, with margins that rival or beat your best crops.
The math is simple: a tray of 72 cells costs you roughly $0.10–$0.30 per plant to produce (seed + soil + labour). Sell those same transplants at $3–$5 each, and you’re looking at $200–$350 per tray in revenue. Run a sale with 50 trays and that’s a $10,000 gross revenue event from plants you started in your nursery weeks ago.
The challenge isn’t demand. It’s planning: how many trays to start, which varieties to grow, and when to seed so everything is sale-ready on the right weekend.
How Heirloom Helps You Plan a Seedling Sale
Heirloom is a crop planning and farm management platform built specifically for market gardeners. While it’s designed to manage your crops
from seed to harvest, its Nursery management and Sales Channels features make it surprisingly powerful for planning seedling sales.
1. Plan Your Seedling Production in the Game Plan
Start by adding your seedling-sale varieties to your Game Plan. For each crop, define the nursery details: tray size, cells per tray, seeding date, and days to transplant-ready. Heirloom’s timeline view shows you exactly when each variety will be ready, so you can back-calculate your seeding dates from your target sale date.
If your sale is May 16 and your tomatoes need 6–8 weeks in the nursery, you’ll want to seed by mid-March. Heirloom will also automatically create tasks for your team: potting up, hardening off, labelling, and staging.
2. Monitor Your Nursery Inventory
The Nursery module gives you a week-by-week forecast of your nursery footprint. At a glance, you’ll know how many trays are in production right now, how many containers you’ll need each week, whether you have capacity for more varieties, and when each batch will be sale-ready.
This is critical for avoiding the two biggest seedling-sale mistakes: overproducing (waste) and underproducing (missed revenue).
3. Create a Dedicated Sales Channel
In the Harvests module, create a Sales Channel called “Seedling Sale” (or “Spring Plant Sale”, “Mother’s Day Sale”, whatever fits your brand). Set the specific dates, and Heirloom will track availability and quantities against that channel.
This keeps your seedling-sale inventory separate from your field production, so you always know what’s earmarked for the sale versus what’s going into the ground.
4. Assign Quantities and Generate Tasks
Use the Harvests module to see theoretical availability for your seedling sale week and assign specific quantities to your sales channel.
A seedling sale shouldn’t feel chaotic. With the right farm planning tool, you can forecast your nursery production, track inventory week by week, and coordinate your team all from one place.
