how can i grow an apple / cherry tree without an sign of a seed, does it needs a cutting with a root?

Answer 1

Your best bet is from a cutting or grafting. Best look up both as I have just a few minutes left to answer this. It's probably easier to take a cutting than grafting, still rooting cuttins will require a rooting hormone. Grafting would be taking your selected variety and grafting it onto another like tree; apple to apple for example. The graft then grows on the new parent. Only the graft will be your selected variety though, the whole tree doesn't magically change over.

Root cuttings aren't a good idea as there's a chance the root is different from the top of the plant. Many modern fruit trees are grafted onto a different root stock, perhaps to cause dwarfing.
