One idea could be to surprise your husband with a fruit tree grafting kit that includes everything he needs to cultivate his own fruit trees. You can also consider getting him a set of high-quality grafting tools that he can use to perfect his skills. If you want to make the gift even more personal, you could research some rare or unique varieties of fruit trees and try to find a local nursery that carries them, and present him with a certificate for his very own fruit tree that he can graft and cultivate. Alternatively, if you have enough space, you could plant a fruit tree together and create a new tradition of nurturing and watching it grow.
Or you can get him a star map with the date of your anniversary.
