Howdy,
--speaking of trees.
I have a Key Lime that could be about 20 yrs old. It's an abundant producer... could be 1000 small fruit a yield. This last frost/freeze the leaves have turned white and are dropping like crazy ... it will be barren soon. Small twig/branches are still green - some tips may be brown but most sample cuts appear green. Question: Does anyone know if it will be OK or is it dying a slow death? A Tangerine 10 ft away is bountifully healthy (good fruit!), my AZ Sweet 20 yr old large tree is fine. As I remember the freeze of 2006 didn't affect the Key Lime with white leaves that are falling like crazy.

My lime tree is doing the same thing. However I see new growth so am thinking it is fine.

Gosh, pulling from way back...it seems like I remember reading that, they should be fine unless the leaves have not started shading the branches, before we reach our blazing hot weather. If you do not have enough new leaf growth to cover the branches by then, you should tie a light shade cloth over the tree to protect the branches from sun burn. Can't remember where I read that...but it seems I did read it somewhere...sorry, not much help

That seems like a totally logical suggestion and probably necessary. Thanks Jayne and Alan! I'll definitely "drop the cloth" if leaves aren't in place by May ~? It's a pretty large tree. Might need help with the cloth. I can ask my tree trimmer to help if necessary. Thanks again!
