I have many types of fruit growing in my garden,but because l have moved them around
when they were in pots,and put them in the ground last autumn with their little jackets covering them ;) 
from frost and snow,l don't know which is which anymore  ??? ??? is the piccy below a Grapefruit  ???
and has anyone grown one before  ??? if so do you have any tips.
This is a close up and has................big spines  :o

It's certainly a citrus of some kind, have you planted it outdoors? :o

I agree with Merry, definately a citrus of some description.  Am no help whatsoever with care though as mine always get smothered in scale and drop down dead!  :'(

It looks like a Lemon tree.  I grew one from seed many years ago and I remember it having, what looked like, thorns on the stems.  I threw it away because it was growing too big for the house - after one year.

Thanks for the replies everyone  :-*

Merry,it is outdoors.

Lily l do have Lemon trees too growing outdoors,but they don't have thorns on,thats the trouble l don't know which is which  >:( :o ;D and forgotton what some of them are  :o ::) except me Avacado  ;)l know where that one is  ;D
