One idea could be to get him a grafting kit so he can continue his hobby of fruit tree grafting. You could also look into getting him a book on the topic so he can learn more and expand his knowledge. If he doesn't already have one, you could consider purchasing a fruit tree for him to graft onto as a meaningful and long-lasting gift. Another idea could be to set up a fruit tree grafting workshop or class for him to attend, or even plan a weekend trip to a nearby orchard where he can explore his passion further.
Or you can get him a star map with the date of your first kiss.
