Just planted an olive tree what do I need to feed it with Or fertiliser

[New shoot]

If it in the soil, it doesn’t really need feeding.

If it is in a pot, it will be fine for a few weeks because of the new compost it has to grow into. After that you could feed it to keep it looking good. I tend to use a liquid feed once a week over the growing season that I use for all my container plants, but any general purpose feed will do.

We bought an olive about 10 years ago, and planted it in a gravel bed.  It is now so huge I have had to have it reduced by half. It was about 25 feet high. I have never fed it or done anything.   Treat it mean - keep it keen.     Mrs Bouquet

You could try Ouzo or Rhaki (which I prefer).

I'll get me coat!    Cheers,  Tony.
