This is not what I meant! The observation of the phenological stages of a set of plants indicates to us very precisely where we are in the "season", much more infallibly than the "guides" or "calendars" (which even "permaculturalists" are however fond of). This takes into account the weather of the year and with great finesse the differences in the situation. Downstairs, in Rosheim, the plum trees are in bloom! At home, nothing !!! (100 m altitude difference and 4 km as the crow flies).
There remains the "risk": a brutal frost such as this April 21, 2017, that nobody, neither the gardeners, nor the meteorologists, nor the plants foresee !!! Must be clear, if I have not been!
Very clear that's what I picked.
My remark was of a general nature about the phenomenon: I sow so much I will eat so much .... .
And that includes the hazards that are of all kinds ...
