I have what is supposed to be a honey-crisp apple tree. It was planted seven years ago. Last year I thretened it, saying; ifyou don't get busy and bloom, I'm going to chop you down. This year there were 5 blossoms.It was planted in rather compacted soil.What should I be doing for this tree?

It is likely that the compacted soil is the reason for this. The only thing I could suggest for a mature tree is to introduce worms into the area. You may need to add a layer of compost and topsoil to get them started, but they will dig down, and open the soil up some. This will let nutrients through, so when you fertilize it will go straight to the tree.
