>>1310401>>1310405Also I live in a "humid oceanic climate" at 50°N (pic related the current state of my lawn, humid indeed - and no this isn't an exceptional drought any more, but the 4th year like that in row), so yeah citrus won't sprout here if you just spit them in a corner (tried many times as a kid)
I even removed the outer, harder shell of the lemon seeds on my second try that got the said 1/6 germination rate (in previous attempts I didn't and nothing sprouted at all)
