Standard apple trees can take 5 to even 10 years before producing blooms and apples. Be patient.

What kind of root stock?

Since it has already developed fruiting spurs, it should be flowering at this stage of development. Has it done so before?

Apples blossom after leafing out although flower buds should be visible before. Ability to flower is independent from fruiting. Even very young trees can flower.

I think it's standard root stock. What puzzles me is it has like 40 spurs and they all have a ton of large fully developed leaves on them. No flower blossom in sight though. But like Kevin said it may just be too young and not in any hurry to produce fruit. It grew like crazy last year and had no flowers then either.I think I gave it too much fertilizer.

I'm far from an expert on apple trees and learn as I go. Rabbit girdling, Deer, hardiness, wrong planting location, disease, root stock and how to prune correctly all had to be learned.

You may be correct about over fertilizing but I've never fertilized a fruit tree in my life so could not say. The birds, bugs, squirrels and any other critter wanting to use the ground under my trees as a toilet do the fertilizing for me, but Maybe I should.

Pruning wrong or not pruning at all will have an effect on apple production. did you prune a little to much? The two trees I still have are about 12 years old and have standard root stock and biennial. I try and keep them no taller then 15 feet tall so I can reach the apples, and high enough to keep the deer from eating the branches. I aggressively pruned a lot of wood the last late winter for the off year 2024 to force them to spread and I had no flowers at all. Usually I get some so I've concluded it was excess pruning. Maybe not.

by the way It took them what I thought was forever to flower and at least 5 years.

So they're 12 year old trees and produced no flowers at all that season,what was on the spurs,,just leaves?

What was the source of the tree? Is there a chance it's a seedling?

I bought the tree from one of the big box stores,Walmart I think. I know it's a grafted tree. It had a Golden Delicious tag on it.

I really never paid attention to what was on the spurs so couldn't tell you. What I did get was more water sprouts then I could shake my pruning shears at. They are thin vertical aggressive branches which don't produce apples and should always be removed along with scaffold branches with weak crotches along with inward and downward growth.

Weak crotches on scaffold branches will ruin years of work if allowed to stay so get them young even if you really really want to keep the branch where it is. The damage they can do later in life is catastrophic. Up to a third of the wood can be removed during a heavy prune so you won't kill the tree cutting off branches. Light and air circulation is a must to produce quality apples and thinning is needed to get the light and air. I want to be able to easily throw my hat through the tree without it getting caught.

There are many good how-to (and some not so good) pruning sites on the internet showing how to shape and what to cut, and should be done every year. For me an apple tree pruned to grow outward and not tall like a Christmas tree is easier to pick and looks cooler, kind of like a huge bonsai tree.
