Last year one of my two trees had no apples and had mildewey tips.
Garden Centre recommended dithane and it's had a regular dose. But
this year likewise, mildewey ends,

Mildew is more of a problem if the apples aren't getting enough water.

no blossom,

That's an earlier problem, doubt id it's associated with the mildew.

Are you pruning it correctly? Have you got knobbly fruiting spurs as
well as smooth non-fruiting shoots? We'd be able to give better advice
if we had more info, eg size and age of tree and variety.

no apples. I've chopped
it down to about a 2 foot stump (if you don't pay rent you get out of
my garden!)

That's a bit drastic!

. So, it it likely thet it will grow good now, or should I
take a short cut and yank up the roots now rather than later?


It'll probably take a year or two to start producing fruiting shoots
again.

The
other apple is well laden with fruit btw

If it's *too* laden, wait till after the 'June drop' (dry summer period
when the tree naturally sheds some of the developing fruit) and if
necessary thin a bit more. If it has too much fruit in one year, it may
exhaust itself and not have any apples next year - and if you're down to
one tree you can't afford that!
