When we redesigned our garden 3 years ago we had to move a tree which had grown from seed brought over here from Iran about 15 years ago. Anyway it was done by professionals and moved into a really big pot which was sunk halfway into the ground. The following year we realised that perhaps the bottom of the pot should have been taken out to allow the roots to spread so we got the guys back in to do it.
Unfortunately over the last year or so the leaves have turned yellowy and started to drop a lot. It has not bore fruit this year either.
Last week I replaced a lot of surrounding earth with manure hoping it would help.
Is there anything else I can do to save it?
