Hello peeps , i have no idea how well , or even if ? , wheat will grow that far north , but i have grown small amounts of wheat , oats , barley ,and rye , off and on over the years .
I grow an old variety of wheat called ' square heads master' . It is from the mid 1800's and grows to about 5'-6' tall .
Most of the grains give about 1 1/2 - 2 tons of grain per acre , plus about the same in straw .
The actual amount will depfend on soil type , soil fertility , weather , altitude , variety , whether they are winter or spring sown types .
An easy way to work out how much you may get is to say upto 1lb of grain per sq yd at harvest .
My winter sown wheat rotted under water this year , previous years cows have had it , horses , sheep etc , nothing is a cert , lol .
How much you need for your flour depends on how much you use , ;-) , if you use 2lb per week then you need 104lb per year . So at 1lb per sq yd that would be just over 10 yds x 10 yds , an acre is just under 70 yds x 70 yds .
You may not get a full 1lb per sq yd , so best double the area you grow , the surplus can go to feed any animals you have . Cheers , Russ .
