Advice on mini orange tree
I have had a mini orange tree growing indoors for the past year and a half. It recently started to lose a lot of leaves, which we have discovered was due to over watering - we took it out of the decorative pot to put it onto gravel, and there was loads of dirty water in the bottom of the pot. The tree had got 18 mini oranges on it each about an inch in size which i have now removed.
The tree has now been outside on gravel for three weeks and i've not watered it, but it is still losing leaves - and the branches where the leaves have come off have gone all brown and woody.
Are these branches dead?
Should i trim them off or leave them on?
Have i rotted the roots by overwatering?
Is there anything else i can do to help it?
The tree has been very healthy up to now with no sign of disease and has always had lots of fruit on it.
Any advice would be greatly appreciated.
