:D I can imaginge! And it was my pleasure!
I'll be bloody honest with you. I'm not the best source for information about that. But as far as I know, most of the fruit trees should be cut either right after the harvest or somewhere around autumn. But I'm nowhere a professional about that. So maybe you can find one of your neighbors with some experience or you may be lucky to find a professionist (gardener) who is willing to tell you some about it.
The internet may be another good source of information. There are so many nice people out there willing to share their knowledge and experiences. <3
Thanks for your honesty on this subject hehe
I've already spotted a few very good books on the subject, but I like the idea of finding someone nearby, and in fact one of the neighbors here, whom I haven't met yet, is a horticulturist... So I'm thinking of trying to get in touch with him :)
Thanks again @aaskablackwolf !
