How much fruit?
No telling.
Nature says how much.
Before I went to war with squirrels and chipmunks, they would strip this tree clean before the fruit was even half size.
That is why you plant all sort of fruit, all sort of varieties of a fruit and all sort of maturities.
The early harvest may not have a crop this year, but the medium or late harvest may. Some apples are biennial and only crop every other year. Birds can eat a lot. Chipmunks and squirrels also strip lots of fruit. If you have deer problems, they can shred a tree unless it is armor plated.
Just put lots of fruit producers in the ground and see what happens. If they don’t work out, then pull em out and put in something new.
It is good you are growing fruit now. It can take many years to be productive. You won’t have to eat dogfood if things get rough!
