I have a cameo apple tree growing in my yard, and I was wondering does it need a companion tree to produce fruit? the tree is 2 years old this year.
Depends how far away there are any ornamental crab apples. I have not heard of Cameo being self fruitful. Here it tends to bienniel bearing so another tree of a different variety might prove double useful.
I have a peach tree in my yard too, will that help? (I don't know much about fruit trees)
