Hi Gerry

Any chance of a photo , which would help in answering your question

also have you pruned it yet , to help it produce flowering spurs ?

Apple trees usually bear fruit anywhere between 2 and 7 years old. There are a lot of factors that determine when a young tree will start to fruit. The variety, cultivar and even the rootstock that the tee was grafted onto will have an effect.

Since you have two different types, one has blossomed and the other hasn't, I'm sure that in this case it's to do with them being different varieties and the Golden Delicious will eventually catch up.

A sign of blossom usually means that the tree will fruit as long as they are pollinated but this is not always the case as anything could happen between the flowers and the fruit forming, i.e. frost, insect disease, etc.

Another thing to bear in mind is that apple trees need at least one other tree of a different cultivar in the same pollination group to pollinate it. Both the Gala and the Golden Delicious are in the same pollination group so that shouldn't be a problem.

The fact that your Golden Delicious hasn't blossomed yet, and so won't pollinate the Gala might not seem as bad as it sounds. If there are other suitable apple trees nearby they could still be pollinated by them as bees do fly a lot further than you might think.
