I have no orange trees as in the UK it was too cold to make them sweet enough to eat, I have an old mandarin tree but its fruit is realy sour unless the weather gets very hot in the summer
I have a few old lemon trees and a mandarin that I have had in 200L pots for about 8 years, full grown trees I bought them that way though from a nursery, never reepotted 100%, just the edges chopped out and new compost packed in down the sides
This is probably the oldest, but I only bought it last year in July, a calamondin
It was cheaap on ebay.....
it had massive frost damage and twig dieback due to turning into a block of ice, it had been left outside all winter with no protection in England, I paid very little for it... about £20 and a couple of gallon of diesel for the van
It has now mainly recovered after spending the last year under growlights and it seems to be quite healthy, it is now in Bulgaria outside
The seller had owned it for over 25 years and said the owner before him was a nursery that was closing. They had used this at the nursery as a display item and for taking bud wood from for about 15 to 20 years or more before that and it was just as big when they bought it from another nursery , he thought it was from reads nursery initially
He said it was repotted in the same pot by removing the top compost last march, just growing in a shop bought peat based potting compost
Im over in he UK at the minute, when I get back next week it is getting repotted in something decent into a bigger pot , the seller said it had been in this one at least 10 years it might have been more....
It has to be at least something like 40 or 50 years old from what i was told
