Hi Mike,

I was curious about what kind of analysis you use to decide what your total planting mix would be and maybe more importantly how you analyze the results. Having been looking over the Web I have found a variety of different metrics applied such as,

"I wouldn't plant anything that I couldn't harvest at least $50 of in an hour"

"I can't plant anything that wouldn't supply at least $10,000/per acre"

Granted that there are some things that people just expect you to have, but beyond that

as a fellow Tiny Farmer, and a one man operation there are some tough decisions to make as far as product mix.

As I started to think about this I found myself mentally dividing my production into a variety of groups, such as

Field,direct seeded,low maintenance(no row covers)

Field,transplants,high maintenance(row covers)

High Tunnel

Greenhouse

I have more groups but I think you get the picture.

Any thoughts?

BTW I really enjoy the Blog and the pictures!

I suppose you should look at your limiting factor and base your primary metric on that. For most people, time would be the limiter. Some people on tiny acreages might be limited by space. The "$ per hour of harvesting" sounds like a good one, though it would have to be modified by "ease of marketing," "square footage used in the field," maybe "post-harvest longevity," maybe many other things.

I'm a brand new market gardener as well. I'm currently planning my planting, mainly trying to get a feel for what people want to buy. More experienced voices should probably chime in now…

I've been thinking about this for a couple of days. I'm heading into Season 6, and I'm still working on a basic, comprehensive production planning system. It's a lot trickier than it seems!

The fairly recent conclusion I'm coming to is that planning how much to plant of what comes down to your personal farming philosophy and goals. A lot will of course be determined by your size and location (access to market), and then, growing conditions and you ability to mitigate less favorable conditions, but even then, there are always many, many ways to go with a market garden, and the decisions really seem to come down to what you're after (in LIFE! :).

On one hand, using hard data to plan the product mix and field quantities is pretty straightforward. You need to do a lot of quite meticulous record-keeping, especially in the first couple of years, and then, crunch the numbers! It's the idea I started with, and I've read about people doing this to the Nth degree, apparently with fantastic, predictable, profitable results.

I started with an easy to track field unit: 50' beds. That way, I could track crops by row feet: a bed of, say spinach, three rows, is 150' of spinach. As long as I recorded dates, yield, harvest/post-harvest time, and sales results, after one season, there'd be a ton of useful data, at a practical, realistic level of detail. If I got 60lbs of spinach from one bed that took 50 days from seed to harvest, sold 50lbs of it at $4, I've pretty well got a handle on spinach performance. With the same data for the whole year's season production, and for all 25+ other veggie crops, I could sit back in late fall and winter, map it all across a calendar, and have a pretty detailed idea of what performed and sold well at each point in the season, and at what relative production cost!

For the actual record-keeping, I had every 50'x50' section and bed (10 per section) marked out in a grid, with map-style coordinates for easy reference (letters across, numbers down). From the north end of the field, a section three down and one to the right would be 3B, and the fifth bed in there would be 3B-5. Simple and effective notation! Crops, varieties and planting dates were meticulously penned in in tiny type on the field map. For the farmer's market, I'd create a weekly one-sheet form listing each crop on sale, usually with separate lines for varieties (for example, two types of carrot), noting starting quantity, unit size and price, and then added a tick for each sale. Harvest and packing time was (and is) pretty well limited since I don't have a cooler: everything's done the day before, so I didn't track that by individual crop, just divided it out evenly. Fantastic!

Two problems quickly became apparent. First, I plain didn't want to sit there poring over all that data (the record-keeping itself rapidly became…painful, though I persevered for the first season). And it's a LOT of data, since I succession plant, up to five or six plantings of almost everything that's cool tolerant and 60 days or under to maturity. First season, I was tracking 80 beds, 120 the second, and 160 since then until last year. Second, there were still so many an accounted for variables, both with the season gone by and for the upcoming season, that it seemed futile to spend the time numbercrunching, if that was to lead to the next year's plan. The really crazy, absolutely volatile and unpredictable weather also started my first year, 2003. Combine that with relatively major production changes each season (new seedling greenhouse, improved irrigation, applying 120 tons of compost, finding that an old washing machine used as a greens spin drier could quarter my hand-washing time, etc, etc, etc) meant that the performance of particular crops could vary WILDLY from year to year, both to the good and bad (overabundance to practically none at all).

NEXT, I started CSA in the second season. This put a big twist on things, a good one for variety and growing fun, but a huge complication for planning. With CSA, I could grow a much wider range of crops and varieties than I could reasonably sell at our fairly conservative, rural farmers' market. With a total traffic of maybe a few hundred people per Saturday, there was only so much market for tomatillos and daikon radish… With CSA, I could include more…adventurous selections, they were even welcomed, whereas the members probably would have purchased no more than 5-10% of the "specialty" crops (including, even, many of the non-red heirloom tomatoes!)… BUT, with the diversity made somewhat practical by CSA, my harvest time suddenly started to get lopsided. Even without meticulous record-keeping, I could see that CSA harvest, for a fixed weekly income, was WAY more costly than harvesting prime market sales crops. Although I tried to keep CSA share content roughly equivalent to market cost (CSA isn't a discount plan), I'd always end up putting in the basics PLUS some "specialty" stuff in the shares. It's fun. People are happy…

Anyhow, I could go on, but no need! I think it's pretty clear that the amount of record-keeping only grows as you try to fit in more and more data. (For good measure, I will add that last year, CSA doubled to around 55 AND I had one full-time helper on a flat weekly fee, plus lots of harvest day helpp. While the field experience with PEOPLE was all-around GREAT, the harvest/post-production turned into a bit of a producion line, banging out 80-100 units of 10-15 crops every week meant stuff like those tomatillos didn't even get harvested. Nice growth on paper meant mini mass production in practice. In hindsight, that aspect I really disliked…)

Of course, in this case, the logical solution is to SIMPLIFY. Grow ONE type of carrot, two or three tomatoes, and so forth. Grow a very limited number of "unusual" offerings: okra, 40+ types of tomato, tiny purple and white eggplant, six or seven types of summer squash…stuff like that just doesn't sell around here, right?! So why grow it?! Well, because, for me, it's FUN, I don't see myself churning out large, relatively uniform harvests of the top sellers, people at the market do gradually expand their tastes. I have nothing against a simplified harvest, that's what most of the other, much bigger veggie growers do, I could see myself happily doing that as well if I changed the entire farming model I started with, which was to be local, diverse, high quality, TINY, and profitable: grow it and they will come… ;)

My VISION, sitll intact, is a pretty standard tiny farm dream: a beautfully balanced giant veggie GARDEN, a happy, loyal clientele paying FAIR prices because they really absolutely swear by the quality, taste, and experience. Tons of diversity, but finely tuned, so there is an abundance of delicious, tender, highly profitable baby salad greens all season, and huge, unbelievably tasty (but so fragile) heirloom toms, and mounds of sweet, crisp, well-sized carrots, but also some okra over here, lovage and tarragon there, Jerusalem artichoke in the late summer and fall… It can definitely work, but it takes a very clear production head, and it's taking me a long time to clear out all sorts of distractions.

My latest attempt for this season is to simply the PLANNING and RECORD-KEEPING rather than the crops. It's a new approach that I'm still working on, but already it feels good (then again, at the start of every season, everything feels…possible!). The basics:

1. Two crop groups: an A list (must have staples, top sellers, most requested) and a B list (lower demand, trial). The A list is simply priority, from initial planning to anticipating and dealing with weather, it's A first (I used to kind of spread effort across everything…no longer). The B list, being lower priority, gets planted in much reduced quantities (by knowing from the start that they're simply not going to get a fair share of resources, I'll PLANT LESS!…sounds obvious, but for me, it's a breakthrough :).

2. A simple revenue per bed tracking system: This year, with 2.5 acres or so, I have 400 5'x50' beds. I'll assign a total income for the year to each. Regardless of the crop, succession planting in the same area, whatever, I'll just add up the sales number for the bed. For CSA, I'll divide the number of items by the weekly income, and that's it, an aribtray flat rate (for example, 8 items in Week 6 at $24/wk for a single share, is $3 for the item).

That's about it! I think it's just enough of a hard copy framework to keep all the rest that's in my head organized. At the end of the season, I should have one simple sheet with a total per bed, and an at a glance reminder of where it came from. The rest is general farming overhead, divide the year's total expenses by 400 and there's the cost per bed. More detail than that, for this type of micro-farm, I really don't need!

So that's what I'M trying. It'll be different, of course, for everyone else.

I do think of alternatives sometimes. For three years at least, my standard "what if I wanted to make the most money from tiny farming" alternative scenario is: shrink the 2-2.5 acres down to 1 acre. Spend all of the annual improvement money on optimizing it for salad greens, and a limited selection of heirloom tomatoes, and grow specialty salad mixes and toms for the urban market (in my case, Toronto, 75 miles away), where I can get literally 3-4x what I've been able to charge around here. Standardize production: fixed irrigation, shade cloth, organic fertilizer. Hire for field labor. Spend at least half my time marketing (which I seem to be pretty good at). There is certainly a ton of demand for this approach. Maybe I'll do it some time, but for now…it's the more romantic veggie garden for me!

Wow, that's really looooong, but I'm not gonna try and edit it, at least, not right now. Hope it's at all useful in some way!

My longest post EVER…ohmygod!! :)

The fairly recent conclusion I'm coming to is that planning what and how much to plant comes down to your personal farming philosophy and goals. This will of course be affected by your size and location (access to market), and then, growing conditions and your capacity to mitigate less favorable conditions (like, no rain, but you're fully irrigated). Even then, there are always many, many ways to go with a market garden, and the decisions really seem to come down to what you're after (in LIFE! :).

On one hand, saving and analyzing hard data to plan the product mix and field quantities seems pretty straightforward. You need to do a lot of quite meticulous record-keeping, especially in the first couple of years, and then, crunch the numbers! It's the approach I started with, and I've read about people doing this to the Nth degree, apparently with fantastic, predictable, profitable results.

And it's a LOT of data, since I succession plant, up to five or six plantings of almost everything that's cool tolerant and 60 days or under to maturity. First season, I was tracking 160 beds, 240 the second, and 320 since then until last year, when it went to 400 (there to stay!). Second, there were still so many unaccounted-for variables affecting production, both in the season gone by and for the upcoming season, that it seemed futile to spend the time number crunching, if that was supposed to lead to the next year's plan. There's the really crazy, absolutely volatile and unpredictable weather that started my first year, 2003 (typical of the wildness, one year was cold and damp—under 40°F nights in August!—with no two consecutive days of sunshine ALL SUMMER). Combine that with relatively major production changes each season (new seedling greenhouse, improved irrigation, applying 120 tons of compost, finding that an old washing machine used as a greens spin drier could quarter my hand-washing time, etc, etc, etc) meant that the performance of particular crops could vary WILDLY from year to year, both up and down (overabundance to practically none at all). With so many crops in such small plantings, it didn't seem that these variables could be meaningfully averaged out for future planning.

NEXT, I started CSA in the second season. This put a big twist on things, a good one for variety and growing fun, but a huge complication for planning. With CSA, I could grow a much wider range of crops and varieties than I could reasonably expect to sell at our fairly conservative, rural farmers' market.

Although I tried to keep CSA share content roughly equivalent to market cost (CSA isn't a discount plan), I'd always end up putting in the basics PLUS some "specialty" stuff in the shares. It's fun. People are happy. It's what felt good and right… It was also expensive.

Anyhow, I could go on, but no need! I think it's pretty clear that the amount of record-keeping only grows as you try to fit in more and more data and…revenue sources. For good measure, I will add that last year, our CSA nearly doubled to around 55 AND I had for the first time one full-time helper on a flat weekly fee, plus lots of harvest day help. While the field experience with PEOPLE was all-around GREAT, the harvest/post-production turned into a bit of a production line, banging out 80-100 units (CSA+market) of 10-15 crops every week meant stuff like those tomatillos didn't even get harvested.

So why grow it?! Well, because, for me, it's FUN, I don't see myself churning out relatively uniform harvests of 6 or 7 top sellers. And people at the market do gradually expand their tastes. I have nothing against a streamlined selection, that's what most of the other, much bigger veggie growers at the market do: strawberries, radishes, peas, beets, snap beans, carrots, corn, tomatoes, potatoes, winter squash, pumpkins, one variety of everything but the squash. I could see myself happily doing that as well if I changed the entire farming idea I started with, which was to be local, diverse, high quality, TINY, 100% hands-on and profitable: grow it and they will come… ;)

My VISION, still intact, is a pretty standard tiny farm dream: a beautifully balanced giant veggie GARDEN, a happy, loyal clientele (farming partners!) paying FAIR prices because they really absolutely swear by the value, measured in quality, taste, and experience. Tons of diversity, but finely tuned, so there is an abundance of delicious, tender, highly profitable baby salad greens all season, and colorful, unbelievably tasty, fragile, premium priced heirloom toms, mounds of sweet, crisp, always well-sized carrots at a proper price-per-pound, but also some okra over here, lovage and tarragon there, Jerusalem artichoke in the late summer and fall… It can definitely work, but it takes a very clear production head, and it's taking me a long time to clear out all sorts of distractions.

2. A simple revenue per bed tracking system: This year, with 2.5 acres or so, I have 400 5'x50' beds. I'll assign a total income for the year to each. Regardless of the crop, succession planting in the same area, whatever, I'll just add up the sales number for the bed. For CSA, I'll divide the number of items by the weekly income, and that's it, an arbitrary flat rate (for example, 8 items in Week 6 at $24/wk for a single share, is $3 per item).

That's about it! I think it's just enough of a quantitative, hard numbers framework to keep all the rest that's managed in my head organized. At the end of the season, I should have one simple sheet with a total per bed, and an at-a-glance reminder of where it came from. The rest is general farming overhead: divide the year's total expenses by 400 and there's the cost per bed. More detail than that, for this type of micro-farm, I really don't need! Adjustment for the next season should be simple, informed and pleasurable.

So that's what I'M trying this year!!

Have more controlled conditions, with fixed irrigation, shade cloth, organic fertilizer. Hire for most of the field labor and spend at least half my time marketing (which I seem to be pretty good at), for example, developing restaurant and specialty retail clients. There is certainly a ton of demand for this approach, at the moment. Maybe I'll do it some time, but for now it sounds like not so much fun…it's still the more romantic field of dreams veggie garden for me!

What a thoughtful and comprehensive essay! I particularly like the A and B crop approach. I'm planning for a selection of dried flowers to bring to the market – they will definitely be a B crop.

I found last year (my first year!) that I could bring an unusual veggie and sell it, but I tried to bring only one unusual thing at a time. So early on I brought celeriac – a pretty hard sell – and then later had edemame. I put out a sample of cooked edemame and the quarts sold very quickly. We do have a fairly upscale market, frequented by summer cottage owners…

hey Carl,

Let me put a slightly different spin on the question: the 'mix' we grow for our CSA is largely determined by what our customers ask us for. We meet with each customer well in advance of the season and get their preferences from a list of about 35 common vegetables that we CAN grow, are GOOD at growing, and LIKE to grow. We then plug this information into a homebuilt spreadsheet that figures out how many beds we need, when to seed, re-plant, expected harvest dates and quantities, and few other useful things. We track from year to year what works e.g. planned harvest dates and quantities vs actual, and adjust accordingly the following year.

We use another homebuilt spreadsheet to do the cash flow projection for the year.Since our income is determined in advance (CSA subscription fees) we just have to manage other costs, mainly labour, to make a profit.

I realize my comments are CSA specific, and it is much tougher if you are selling at a market with less 'advance' contact with your customers.

btw mike I think our 'visions' of the perfect small farm are congruent; I love the variety of things we grow. I too have looked at specializing in salad stuff, or a 'salsa' garden, but it would not be as satisfying (dare I say boring) to only grow a few things – too much like that production line you mention
