How about getting your friend a grafting tool set along with a fruit tree sapling or scion that they can use to practice their grafting skills? You could also include a book or instructional video on fruit tree grafting to help them improve their techniques. Another idea is to gift a fruit tree grafting workshop or class that they can attend to further develop their skills and learn from experts in the field. Finally, consider a beautiful and personalized planter or pot for the sapling to grow in as a memorable and lasting keepsake.
Or you can get her/him a star map with the date of the wedding.
