Great news! They are ripening right now! 😄 I tried the tips offered by you all and also the last site linked by @kellyromanych which was the most specific one for my needs. Even then I tried the 4 methods of: slight give, twist off tree to pick, smell and color. The ONE I tried (tip was try 1 and if too tart leave rest to try another day) had a very small amount of “give”. I was able to twist it off tree without dropping all the rest there. It was bright green but had a little yellow on one side, and after I picked it. stem end did smelly “limey”.

Son and I tried each half this key lime small lime by squeezing juice on a tortilla chip and a sprinkle of salt on top. (I was shown this by a Hispanic friend in Tucson at a full Mexican restaurant). We were happy. Now we’ll wait a day or 2 longer and pick only as we will use that day. I think since we extra watered this tree over the last 5 months is why there’s a bumper crop of limes.

Now, to check that link for the yellowing leaves issue (thanks @meganL )

Questions: Mexican Lime tree fruit
When should I pick them?
Are these limes ripe when yellow?
Do I use them like regular limes?
FYI our old tree may be over 30 years old and likely had poor or limited care in the last 10 years. It has been dying and lost about 1/3 the tree in the last 3 years. In extreme heat the leaves quickly go to yellow or yellow green. But the live branches are producing the most and largest limes in three years. Help! Need advice. #Botany #Arborists #Tree #CitrisTree #Arizona #Phoenix #Limes #Citris
