Here is the 2nd plant. Any ideas on which citrus tree this is? I'm guessing grapefruit?? THANKS!!!
those thorns look wicked. i couldn't tell you what variety w/o the fruit.
Judging from the leaf it is not grapefruit. The size of the thorns would lead me to believe it is grown from seed, or else the original tree has died and these are all sprouts from the root (rough lemon?). Just guesses; if you crush a leaf and smell it, does it smell like lemon, orange?
