Market Garden Planning Software for Canadian Growers

Running a market garden in Canada means juggling a complexity that hobby gardeners never face. You need to harvest salad mix every week from May through October, time your tomato transplants to hit peak farmers' market season in zone 6b Ontario, and keep your CSA boxes full without flooding any single week with zucchini. One miscalculation in your succession planting schedule and you've got a three-week gap in lettuce — or worse, three weeks of nothing but lettuce.

Good planning software doesn't just help you keep track. It does the calculation work that used to fill whole notebooks: days-to-maturity math, succession windows, bed rotation, yield targets per square foot. Here's what Canadian market gardeners are actually using — and how the tools stack up.

What Market Gardeners Actually Need from Planning Software

Most garden planning tools are built for home gardeners. A market gardener's needs are categorically different.

Succession planting windows. You're not planting one bed of spinach. You're planting a new bed every 10–14 days to maintain a continuous harvest. The software needs to work backwards from your harvest dates, account for days-to-maturity by variety, and tell you exactly when to start each succession indoors or direct-sow outdoors.

Zone-accurate transplant dates. Canada's growing zones vary dramatically — a zone 5b grower in Sudbury has a last frost date weeks later than a zone 7a grower in the Fraser Valley. US-built tools that use USDA hardiness zones and generic frost dates will give you dates that are simply wrong for your operation. A single mistimed transplant in a shoulder season can cost you a week of productive bed space.

Crop rotation tracking. Keeping brassicas off the same beds year over year, rotating solanums, managing nitrogen fixers — this needs to be visible across seasons, not reconstructed from memory each spring.

Yield calculations. Knowing that your 30-foot bed of mixed lettuce should yield approximately X pounds per harvest at biointensive spacing is the difference between promising your CSA members one thing and delivering another.

Multi-bed management. A 1–5 acre operation might be managing 40–100 permanent beds. The software needs to handle bed-level planning, not just a general crop list.

Market Garden Planning Tools: How They Compare

| Tool | Price | Succession Planting | Canadian Zones | Yield Calc | Learning Curve | |------|-------|--------------------|--------------|-----------|--------------:| | MyGardenPlanner (Market Gardener) | $19/mo | Yes — built-in calculator | Yes — Canadian zone data | Yes | Low | | VeggieCropper | ~$15/mo USD | Yes | Partial (Ontario-focused) | Limited | Medium | | GitHub Excel Spreadsheet | Free | Manual | Manual | Manual | High | | Heirloom.ag | $99+/mo USD | Yes | US-focused | Yes | High | | Tend | $49+/mo USD | Yes | US-focused | Yes | High |

The GitHub spreadsheet (a popular free option) is a legitimate starting point, but it requires you to maintain the date math yourself. When your last frost date shifts or you add a new crop, the cascade of formula updates becomes its own part-time job.

US-focused tools like Heirloom and Tend are built for American operations. Their zone data references USDA zones and average frost dates for US cities. A grower in Kamloops, BC or Truro, NS is working with dates that don't reflect their actual growing conditions — and the price point assumes a farm management budget that most 1–5 acre operations in Canada don't have.

MyGardenPlanner for Market Gardeners

MyGardenPlanner's Market Gardener tier ($19/mo) is built around the planning workflows that small-scale Canadian commercial growers actually use.

Succession Planting Calculator

The succession planting calculator is the core tool for market garden scheduling. Enter your target crop, your harvest frequency (weekly, biweekly), your zone, and the calculator works backwards through days-to-maturity to give you a complete sowing schedule for the season. For a zone 6 Ontario grower targeting weekly salad mix harvests from mid-May through October, this replaces a full page of manual date arithmetic.

The calculator pulls from Canadian frost date data, so your succession windows reflect your actual last and first frost dates — not an average from a US city with a similar zone number.

Biointensive Spacing and Bed Planning

The biointensive growing method — popularized in Canada through Jean-Martin Fortier's The Market Gardener — achieves high yields from small permanent beds through close plant spacing, deep soil preparation, and careful succession. MyGardenPlanner's bed planning tools support biointensive spacing grids, which means your yield estimates are based on actual intensive spacing rather than conventional row spacing.

For growers following Fortier's approach, this alignment matters. Your planning tool should speak the same language as your growing method. See our guide to biointensive growing for more on how this methodology translates into bed planning.

Multi-Bed and Multi-Crop Management

The Market Gardener tier supports planning across multiple beds simultaneously, with crop rotation tracking that carries forward across seasons. You can see at a glance which beds had brassicas last year, which are due for a legume rotation, and which are currently allocated to your spring successions.

The planting dates for Ontario and other provinces are integrated directly — no manual lookup required.

AI Planning Assistant

The built-in AI assistant can help with planning questions specific to your operation: "What succession interval should I use for head lettuce in zone 5b to fill a 10-member CSA weekly?" or "Which brassicas perform best in a short-season zone 4 climate?" This is particularly useful for growers new to market gardening who are still calibrating their succession timing.

How MyGardenPlanner Compares to VeggieCropper

VeggieCropper is the closest Canadian-built competitor — it was created by Ontario grower Evan Quigley and reflects genuine on-farm experience. It's a legitimate tool, and growers who are already using it are working with something purpose-built for Canadian market gardening.

The key differences come down to scope and methodology alignment:

Canadian zone coverage. VeggieCropper's roots are in Ontario. MyGardenPlanner covers zones across Canada — from zone 3 growers in the Prairies to zone 8 growers in coastal BC — with province-specific planting date data.

Biointensive methodology. MGP's spacing and yield tools are built around biointensive principles. If your operation follows the Fortier method (or aims to), the planning assumptions in MGP align with your practice more directly.

Free tier for evaluation. MGP's free planting calculator lets you evaluate the zone data and date calculations before committing to a paid plan. VeggieCropper requires a subscription to access planning features.

Pricing. At $19/mo CAD, the MGP Market Gardener tier is priced for small operations. See the full pricing comparison.

Getting Started: From Free Calculator to Full Market Garden Plan

The fastest way to evaluate whether MyGardenPlanner fits your operation:

1. Use the free succession planting calculator at mygardenplanner.ca/succession-planting. Enter one of your core crops — salad mix, radishes, or spinach — for your zone. See whether the succession windows match what you'd calculate manually.

2. Check your planting dates using the free calculator. Verify that the frost date data reflects your actual location, not a nearby city with a different microclimate.

3. Upgrade to Market Gardener if the data looks right for your operation. The full tier adds multi-bed management, crop rotation tracking, yield calculations, and the AI assistant.

Most growers can build their first complete season plan within a few hours of setting up their beds and crops. The succession calculator runs automatically as you add crops — you're not rebuilding schedules from scratch each time you add a new variety.

Market garden planning in Canada has a short window to get right. Your succession schedule either works or it doesn't — and you find out in May when the first harvest gaps show up. Start with the tools built for Canadian zones, then refine from there.
