I did actually grow a Finnish field bean last year, called Hankkijas Mikko. If anybody in Finland has some info about this bean I would like to hear it!



Hi!
From what I could gather, Vicia faba 'Mikko' is evolved from old heritage varieties from eastern Finland, and it is the oldest listed commercial broadbean in Finland. I have two years old 'Kontu' also, I haven't checked how well will it germinate. It is the most profilic and early of our Vicia faba. I can send you some, if you are interested in trying.

I would just like to bump this again, how has the seed exchange gone so far?

I am looking at moving to Finland at the start of 2019 and am looking at starting my own food forest from scratch. Anyone in the Lahti area?



Well hehe..It has been totally quiet . I've been busy bee sharing graft material, and not so much of seeds. I am from Helsinki, so it is quite near to go to Lahti, do you have some seeds that you need?

Oh and if the quince message was for me, I'd have to say that those seeds I don't need right now thanks.

Thanks John for the input!
I have always thought that Cydonia oblonga is just an tree version of Chaenomeles japonica, when it comes to the fruits. I guess I must check the specialty stores for a quince fruit, to truly compare them.
If thorns are not an issue, I have loads and loads of the common variety seeds, collected from the fruits I collected. Also I may have 10 or so seeds from the Sirius cultivar, bred for fruiting and thornless, if that is alright. No idea how it compares to Cido though. Both are bred for fruiting purposes, one in Latvia, and one in here Finland. Ours will take -30C /-22F without damage. I have also never heard that late frosts would do any real harm to the flowers, but on this regard I can't say from my own experience.

Chaenomeles japonica, the flowering quince,  is used often here in Finland as a ornamental for its gorgeous spring flowers. We have cultivars here called 'Sirius' and 'Venus', they are without thorns. Still It should be noted that this fruit is much more close to quince than it is to citrus (chaenomeles japonica is called a "rose quince" here in Finland. Yes, the taste is often compared to citrus, because it pushes the same buttons in your mouth, but the actual taste isn't like lemon...it is like it's own and possible closer to quince. That being said I haven't tasted and actual quince, since nobody grows them here. BUT as I looked through recepies for quince jams, they very often said that you can use flowering quince exactly the same way as quince.
I collected some of the Sirius-cultivars, and took out the seeds. They sprouted after cold stratification easily, so they are viable from seed .

Thanks for the inputs!

We don't use the USDA hardiness zone here, but if the lowest temperature is the key nominator..then yes, zone 5 would be most appropriate. We also don't count our chilling hours, since just about every plant sure gets enough of them here. Growing degree hours we can get nowdays over 1700, but not every year. We really don't have bad droughts at summer, and winters are mostly wet with temperatures jumping between -23 and +5 Celsius.

I have many currants and their relatives, all traditionally grown here. Mut after the climate change has been happening, I'd like to try something "exotic" in here. Thus pawpaws, persimmons and nut trees. Mulberries seem to do okay, but for some reason nobody here sells anything but wild Morus alba/Morus alba var. tatarica.  I think I could and should at least try Illinois everbearing. Wild mulberries mature in early July here usually, so cultivars might be viable option.

Of course regarding pawpaws and persimmons, I should try to find as early ripeners as possible...right?

Haha, I bet! I guess it still boils down to the Growing Degree Days..they must be early ripening, since nothing ripens here anymore in late october . No light, no real warmth.
I wish I could read chinese/japanese, I bet they have tons of information about Diospyros kaki in their language :/ .

Most likely some sort of walnut. The cones are premature catkins, and the leaf scar is quite unique, pointing to walnuts.

if there is a "mustache" on top of the leaf scar, then it points to Juglans cinerea , aka butternut.

David
your apples are doing well



That's nice to hear! Unfortunately my graft skills were subpar, so no luck with you scions this year...but two of your walnuts sprouted .

And regarding Diospyros kaki....really?? I thought that they can't stand much frost, and require way more temperature sum/accumulated temperature than the american version. We have here about 1700 per year (Celsius) , would that really be enough?

And someone could also tell me if you don't know what I'm talking about regading the accumulated temperature sums...I am not sure If that is the proper english term.

Hello everyone!
Has anyone had success OR notable failures growing persimmons, pawpaws or nut trees near the oceans, or the big lakes? Preferably in northmost USA or in Canada?
My pawpaws seemed to survive their first winter here in Finland, so I am optimistic...but I have no clue if Diospyros virginiana (american persimmon), or any edible Juglans/Carya -species will produce. Hazel will do just fine, we have native  european hazel here.

Hey!
I couldn't find any precise information regarding used coffee grounds, so I'll just drop this here....
Eurofins Viljavuuspalvelu Oy is a company that does pretty much all the lab testing of soil samples here in Finland, and they have tested, just for the kicks of it, used coffee grounds the same way they would any soil. I have attached the results in picture. You should pick out all the info from there even if it is not in English. Or I can type them alse here.....

pH: 5,4
Calsium, (Ca)  milligrams per litre: 580
(P),  mg/l :6,7
(K), mg/l : 310
(Mg) mg/l: 450
(S)  mg/l: 25,7
(B)  mg/l: 0,3
(Cu)mg/l: 3,9
(Mn)mg/l: 14
(Zn)mg/l: 2,3

Hope this is useful for someone!

Edit: Unfortunately they didn't test Nitrogen, but from the conversation where I found this I gathered that most of the nitrogen nitrates have leached away while making the coffee, and the rest (not much) will come available after the bacteria have started their  processes. If anyone has more definitive information about the N-values in used coffee grounds, do tell!
