Hi Pasquale:Very Interesting ,that you have 10 varieties.
I know in zone 4 The heat units are very low for ripening fig fruits.
I would like to Know if you got ripe fruits,the natural way,outside in the sun,and not using a greenhouse to lenghten the season.
and if so wich varieties,got ripe,if you can name or describe it?
Thanks anticipated,for answering to this one!
