Apples and pears

The apple and pear trees in my garden are loaded with fruit to grow.
I do not know if I should remove some to allow for the rest to grow or just to leave it be? :?:
Also the apple tree is not growing in height but in width (4 ft high and 5ft wide). Should I support the bottom branches (about 1ft high and 3ft loong and full of promising fruit!) ?
I do not know the variety of apple it is as we found the tree dumped in our garden when we moved in.
Also the pear tree is sky high. Is it a good thing?
Thanks for your advice,

Lily

I dunno if it was muntjac somewhere else or someone else I saw on TV talking about this same subject (before I found this forum), but my God, it works!

I spent many hours during January lopping off dead branches and generally trying to get a "goblet" shape in the branches of our apple tree.
I cut any live branches off at a 30 degree angle with the face of the cut pointing downward - very clean cut - and painted as advised.

The amount of blossom we got this spring is double last years, plus you can almost see that the tree is happier and will produce a far greater amount of fruit because of the heavy pruning, at least, I hope so.


The wood from January's treatment also burns great on the BBQ
