I attach some close-up photos! I was between ulmus parvifolia or zelkova, but i found on another website how to spot the differences between the two, and so i think it is a zelkova (but i still have my doubts)!
What do you think?
Also, when watering it, do you find it a good way to soak the pot in water for 2-3 minutes? I was advised to water it that way when i was growing my last bonsai a few years ago, but some say it is not the most ideal way
