Transferring a pot grown Olive Tree to the garden
I have a pot grown (and bound) olive tree, about 10 years old and straggly, but perhaps 5 foot high from the top of the pot. I want to transfer it to a permanent site in the ground . However, the site we have chosen has been lawn for the last 30 odd years at least. We want to take up a circle of turf, maybe 4 foot in diameter, and plant the tree so it is in the lawn if you get what I mean. The site is south facing and sheltered, and the olive has lived permanently outdoors, unwrapped in winter with no ill effects for 7 years now, so is fairly robust. We are in Kent.
What prep work do I need to do to the site to get it in the best possible condition for the olive? Fertiliser? compost? nothing? How far should I dig down, or is this basically a bad idea, and the olive would be better off somewhere else.
Any ideas about how to prepare the olive for its new home?
