If you put an apple tree's limb onto an orange tree, will the limb still make regular apples?

Question

also what's the term for doing something like that?

Answer 1

The process is called grafting.

No, the apple-orange graft will not work.

Answer 2

Grafting

And from what I understand of it, the plants need to be similar for a graft to take successfully.

Apples & oranges are from 2 totally different sorts of plants & rarely grow in the same climates.

Answer 3

You can only graft plants from similar species. Apples and oranges are way too different. You could graft 2 kinds of apple trees, or even 2 kinds of cactuses.But Not apples and oranges.

Answer 4

Not on this planet. You can only graft  plants of the same genera, so you might get certain types of citrus that will accept a graft, but apples to oranges is not possible.

Answer 5

yes, it's called grafting, and you can buy certain compounds that will help the two grow together.
