Landraces Garden in Switzerland 2026

I plan to document my whole garden in here and just crosspost the relevant info to the Focus crops threads. This year I have the following main landrace projects, the project that are also a focus crop are bolded:

  • Continuing my Maxima landrace, with my seed from the last years, some contributions by @Hugo and some seed I bought or exchanged
  • Testing polepeans (which varieties fit my conditions?), sowing some alleged crosses
  • Testing Tomato varieties (which fit my conditions?), sowing crossed seed from @JesseI, possibly some hand-pollinations (if I have time, a pretty big if, to be honest)
  • Participating with Favas in the Focus crop, testing three different sources/ varieties of Fava seed

Also Landrace projects, but more side character:

Additionally, I plan to post many pictures here and ask many questions, just like a garden Diary has to be.

Documenting my tomatoes:

On the 22.3 i sowed my tomatoes. I used a mix of commercial soil and volehill-soil. I did not presoak the seeds because of time constraints. I sowed them in two flats with 28 cells each so, 56 cells in total.

I sowed the following:

  • Meat tomato seeds I saved myself in 2024, 7 cells
  • Seed mix of heart and egg shaped tomatoes + black cherry I saved myself in 2024, 7 cells
  • Domestic hybrid swarm F2 and F3 2024 by @JesseI, 7 cells
  • Lycopersicum x cheesmaniae F2 by Jesse, 7 cells
  • Travellers tomato I got at ZMAG from Petra, 7 cells, some sources say that that this may have a somewhat ouctrossing flower structure…
  • Assumptas Wintertomate and Black Egg (probably old seed), both said to “be in danger of out-crossing”, which to us is not a danger but a chance, 4 cells each
  • Thomas Green, 4 cells each, old seed
  • Tigerella, Anastasia, and Buschtomato (determinate tomato) Mondstein, 3 cells each. This was really old seed I just wanted to be rid of, to be honest.

I put them in front of my window and on the 28.3 many seeds had already sprouted. There seems to be no difference in germination speed between the different seeds apart from the old seed, which germinated hesistantly, but what can you expect, this seed is from 2020!

The newer seed came up very well, even though I have no supplemental heat, my house is between 18 and 20 °C. The next challenge for the seeds will be the low linght conditions. I have no grow lights, just the window. I rotate the flats daily, because the plants grow strongly in the direction of the window.

Question: How long should I wait to cull? In each cell i can cull the stragglers that germinate later than the rest, this I can do already now. But between the other plants I see no differences right now. Do I wait for the first true leaves and cull all plants than take longer to make first true leaves?

On the 20 of May, I planted out my tomatoes.

This is the first year where we don’t keep the tomatoes in pots. Instead we made a Hügelbett against the south side of our cow stable, where the squashes were next year, but directly against the stable wall (It is concrete for the first 2 Meters, so should be no problem). I made a long heap of tree prunings, then we heaped manure on top during the winter and in spring, we collected the soil of mole and volehills all over our land and put it on top of the manure. I installed drip irrigation, since no rain reaches this location.

Since we don’t have to water the plants by hand, we can afford to have many more plants. I know that many people on this forum propably think: “Whaaaaaaat, drip irrigation. Is she crazy? Does she want to coddle her tomatoes? What about adaptation? What about low tech?”

Well yes, these are all noble goals. But I also want some tomatoes to eat. And I hope that this system is enough improvement on our previous system (if you can even call it that), so we get some tomatoes. And we still have high humidity, cold nights and the possibility of unfriendly weather in summer, so I believe there is still plenty of selection pressure on the plants.

Additionally, since tomatoes grew so badly all these years (in the pots) it was not possible to document which plants were a little better, since all were so bad. For example, a black krim tomato made not more that 2 fruit all summer. I believe one problem was probably the nutrient situation in the pots.

But now the roots have more space, and a better nutrient situation with less work for us during the summer. Therefore I hope to see differences in vigour between the varieties (or sources) I have AND have time to document it. I am not at home right now, but I have definitely seen already quite a difference in growth habit and vigour between the plants.

Additionally, I planted one pole each of:

  • Xaver, a old variety from Liechtenstein (testing)
  • a variety I got from an italian aquaintance (testing)
  • Dasinger Blaue
  • Fasoi grisoni
  • potential cross Fasoi-Dasinger
  • the Amish gnuttle lookalike that appeared in my seed

The potential crosses will be almost all kept for seed, the other poles are also for eating green. Additionally, I still have seed from the potential crosses for next year, since I don’t hvae capacity (mainly the room) for many polebeans thhis year)

This spring was brutal for pole beans, many plants were eaten to the ground. The pole of the Amish gnuttle look alike was eated to the ground by snails. Luckily I have enough seeds to try again next year, maybe protect them more.

The tomatoes are thriving. Last week I made some notes and photos ( I did not have time to look at all the varieties)

  • Black egg: Scraggly plant, closed flower structure. Nothing promiscous about it. Unless the tomato is very good, these are not keepers
  • Assumptas Wintertomate: very vigorous, strong leaves, has already set the first fruit, so very early. Flowers don’t look promiscous to me?
  • Tigerella: Somewhat scraggly, only few flowers
  • Buschtomate Mondstein: Very strong, sturdy stem
  • Thomas green

Cheesmaniae crosses by Jesse: No promiscous flowers, all very vigorous growing. All the plants on the right of the row thar allowed to sprawl all over are the Cheesmaniae crosses. Beautful plants

  • Domestic crosses jesse: There are some remarkable plants

1. Plant in its row: promiscous flowers

A plant in the middle of the row:

Next to it:

A very bushy plant:

I wouldn’t expect promiscous flowers on crosses that are 50% cheesmaniea or pimpinellifolium, at least in the first few generations. To me there seems to be 2 ways to have promiscous flowers. First is to have long stigma like in exserted orange, which seems quite rare and I’m not sure how easy it is to stabilize in promiscous population. In any case, I didn’t have many varieties that had the trait when I started so I don’t expect to find it much. Second is those exploded flowers like in your pictures. They are related to bigger, mostly (?) beefsteak type fruits. As those wilds seem very dominant in the small fruits, the flowers aren’t promiscous at least in the early generations. I had slightly increased fruit size in the F3 generation (which might be what you have also), but still fairly small fruits and so not really promiscous flowers either. Both cheesmanie and pimpinellifolium crosses seem overall more vigorous than domestic. 50% habrochaites seem to have some with big fruits and promiscous flowers even in F2 generation, and as my plan is to merge those 3 populations, I would expect there to be some promiscous on the population that has all those wild species. I have first grow-out of that cross population, but haven’t really paid much attention to flowers. Right now more important trait is that they flower early as habrochaites tends to have slightly later flowering and some seem to have inherited that trait. Have to check the flowers just out of interest, but that I’m going to select for only in the later generations.

Thank you @JesseI for this very interesting information about flower types in tomato. This tracks with what I have seen in my plants.

The plants I marked in the beginning of July as having promiscous flowers turned indeed out to be Beefsteak-types (what we call Fleischtomaten - Meat tomatoes here).

I picked the first significant quantity of tomatoes on the 6 of August. Below, I shall describe the fruit and add a photo

Conventional varieties:

Fantasia F1:

This plant I bought because I thought that my own seedlings looked small, in the hopes of getting some fruit sooner than with my own plants. A basic red tomato

Tigerella:

As the name implies, a striped tomato. The stripes are dark green on light green while the fruit is unripe and is quite suble in fully ripe fruit. The fruit seems to be thin skinned, since one ripe fruit has burst.

Travelers tomato:

The seeds for these plants came from Petra at ZMAG. The plants themselves are vigourous, while the fruit have not yet convinced me of their merits. The taste seems to be quite mild to put it diplomatically. Or if one is to be blunt, the words boring, lacking in acid and sugar could rightfully be used. It seems to be a problem that the ripest segment is rotting while the others are not yet ripe. On the bright side, sperating the segments from each other without a mess works perfectly well. Interestingly, one of the seven plants I have, has not such chaotic fruit, but they are more or less distinctly lobed. i marked this plant, but in the chaos of the tomato patch, i have not found it again.

Assorted cherry tomatoes I bought for an earlier harvest

Domestic F2 and F3 hybrid swarm by Jesse:

These plants really came through as some of the earliest bearers and I am just so in love with some of them.

The first plant in the row has some beautiful violet- yellow fruit and seems to be a heavy bearer. While the anthocyan is quite heavy in unripe fruit it is more a shade on the ripe tomatoes. Of course I am biased because it is my plant, but is it not a most attractive fruit? For record keeping I shall call this plant Antho yellow Fleisch 2026

The next plant to have ripe fruit is also yellow and also a Fleischtomato, but distincly lobed, and pure yellow. I have also marked this plant as having promiscous flowers and this fits with your experience @JesseI since it is also a Beefsteak. It may be the plant I marked as being very bushy, but I can’t really say anymore.

The next plant is a Salattomate - Salad tomato with yellow fruit, but it is not a normal yellow, it has a a cool undertone, almost salmon that doesn’t come through in the picture. Because I am an idiot, I didn’t mark to myself which plant I took it from. Because of the chaos of the tomato patch this means that I can say nothing about the plant itself. I literally do not know, where I took this fruit from, except that they came from Jesses corner of the patch.

A big cherry or small Salattomate with an intriguing bronze fruit color. This is a plant is marked as undesirable to myself, because it has a very thin, whispy, lanky growth habit, with a very long internode and sparse leaves. But it has somewhat redeemed itself with a luxurious setting of fruit.

Then the plant I refer to as Düsterwald (Mirkwood) since seeing the fruit. A very washed out, pale red, combined with a dark, murky green. i can just imagine Bilbo and the dwarves looking at this tomato and deciding that starving would be better than eating these fruit. I just looks sinister to me. I love it. (And yes, they are ripe)

Then some basic red salat tomatoes, nothing special about these.

Lycopersicum x cheesmaniae F2 by Jesse

These have evolved into a veritable jungle with very many fruit, but none ripe yet, apart from these 3 yellow ones. And they are not even that small!

Yesterday my partner and I made Tomato Sauce and of course we tried all the tomatoes and made some notes. I took seed from almost all of them.

Fantasia F1: Basic tomato, nothing special, no seeds taken since I only bought it to bolster the yield of my patch

Antho Yellow Fleisch: we both found it nothing special in terms of taste, definately not bad, just not flashy. Very nice creamy meaty texture

Yellow Ribbed Fleisch: my partner liked this very much, he described it as refreshing! I also liked it but didn’t get what taste component he meant by refreshing. Anyway, a very nice meaty tomato. Negative is that the picking of the fruit is somewhat complicated, since it fruits in tresses (of 5 to seven fruit I would guess, have to look again). The upper fruit ripen faster of course. But since the fruit sit very close to the stalk and there seems to be no designated breaking point for the stalk, it is very difficult to pick the upper fruit without damaging the stalk that should feed the lower fruit.

Salmon: hard, but very thin skin, fruit on the acidic side, we both gave 5/5

Bronze: 5/5, balanced, full taste, very good

Düsterwald: 3/5 and 4/5 points given

Lycopersicum x cheesmaniae F2 by Jesse: bland, no seeds saved yet. In the wild tomato jungle many, many fruit are waiting to ripen. But either they are to shaded by the plants themselves which just grow like they want, or small animals are eating all the ripening fruit and leaving nothing. While the second seems quite likely, I can’t imangine animals eating everything so cleanly that I neven even find traces of ripening fruit. Most animals are after all, quite the messy eaters.

Generally, I regret how we planted our tomato bed. I had about 65 tomato plants (some cells I left two and broke them apart when planting them out), and then i bought about five plants for yield. We planted them much too close together, because we could simply not imagine the vigor these plants would have. All tomatoes we had up until now were more like sad little strings with little leaves left and right. They made one main stem and sad little branches. They had not enough water, nutrients and space in the pots we were forced to have them in. But now in our bed, they have the water, they have the nutrients, and even if above ground conditions are very crowded, they have much more root space underground than they would have in a pot. Combine this with the warm weather and we have never had tomato plants like these.

So, these plants are absolute monsters, at least 10 side branches per plant, more like twenty, branches as think as a farmers thumb, rambling, fighting for space and light, climbing over each other, swooping down to the ground and climbing up again. It is pure chaos. Theoretically, each plant has a stake, a some we bound with strings back to the wall, but is never enough and now we can barely get in.

And to make matters worse, the seven Lycopersicum x cheesmaniae F2 plants I left free to ramble about on one side of the bed in front. They spread, and spread and spread and if I want to reach the plants behind, I have to wade through them. As if this was not enough the pole beans have left the poles, are binding the tomatoes together and are looking for world domination.

The two courchette plants at the ends of the row are somewhat more restrained, but also take up more space than thought. In the cool and wet summer of 2025, our courchette made one fruit all summer and had propably never more than 10 leaves. This summer, we have already picked more than 10 fruit per plant and they take up more than a square meter on the ground and are using the space very efficiently by also using the tomatos as a trellis.

And then lastly, the two zuchetti my mother planted pump out fruit like crazy, which is great. What is less great is how they don’t let me access probably three meters of the bed, because everywhere I would like to stand, there is either an leaf or a stem! And if I find a place to stand down betwenn the leaves, they attack me with their very scratchy leaves.

So, all in all, harvesting is an adventure.

Plans for next year:

  • Two instead of three rows of tomatoes. Plants in a diamond grid
  • No extra stuff in front of the tomatoes except basil and other herbs
  • Make a second bed for the courchettes, the zuchetti, the wild tomatoes
  • Put the pole beans somewhere completely different.

I think I can top that, but unfortunately was unable to find good picture of it. It had stronger purple as ripe (although that is also affected by how much sun it gets so not all fruits were as purple) and it had glossy white stripes. Yellow was also maybe little lighter. I do get different striped fruits from the same mix, but obviously it’s not very common. Must be recessive trait and maybe also need combination of some sorts. But you might get some of those in the future. Also noticed first striped fruit in dom x pimp f4s, although the stripes are little unusually spaced out. Like half the amount of tripes you’d get normally. Curious to see them ripen.

Those might need little more time to ripen. They first turn yellow, but should get little orange when they are ripe. Lots of seeds is just unavoidable result of wild crosses. Generally it seems wild traits are more dominant, but with cheesmanie crosses they seem more dominant than with half pimps. There was little more variation in F3 and this year there also seems like there are some that don’t have cheesmanie type leaves. Probably will get different growth habbits also. Habrochaites crosses seem quicker to loose their wild ways. Or there is more variance in F2s; those that are like F1 so almost like habrochaites and those that are indistinguishable from domestic. Bigger fruits and more not as heavy growth. Unfortunately I made the mistake of using mostly the former in my 4 species crosses last year so the growth is quite heavy. This year I made crosses using domestic types so maybe the results are more manageable next year.
