Our apples seem to be more tart than the ones you'd buy in the store. They're also smaller and more prone to bugs, although that last bit may be because we don't use pesticides and so on. I used a bit of diatomaceous earth on the Japanese beetles this season and it worked like a charm.
I spent a little time looking through my old pictures dating back from our planting the tree and Emperor and Elf's adventure of picking the first apples. Perhaps apple trees yield more as they grow older - here's hoping! I am starting to doubt that this is a "dwarf" tree as we were told just based on the size of the thing and the fact that it took so long to get a good crop in. Dwarf trees are supposed to yield a bit earlier. Hmm. Any gardeners out there have an opinion? I popped a photo here so you can see how tall the tree is - the cars are parked on the north side of the tree.
