We bought a lemon tree at Auchun about 4 years ago.We planted it in a large pot and left it ouside in all weathers.We keep it well watered during the very dry seaon.We give it a little plant food about once a fortnight..It has grown in these conditions well.We know little about gardening so just hope!.It is now around 8 ft. tall and covered in lemons some are yellowing and we pick as required.There are not a lot of leaves for some reason, mainly fruit ,which is hard to understand as I thought the fruit would get most of their sustenance from the leaves as well as the earth.We are on the coast near Beziers so I suppose the climate is reasonably warm.
