Doesn't look like anything more than the oldest leaves dying out, like normal this time of year. Don't panic!

Kevin : )

Nice pics and nice tree. I agree with Kevin as usual. It looks like it's just shedding the older leaves. I just spent a bit of time this morning plucking the same off of my very tiny grapefruit tree, and raking up the same from my pretty large lemon tree. All looks good to me.

And you've reminded me, I don't have a single lime in this garden. I've always grown them in the past. Hmmmmm.....

I do have lots of other citrus, plus a fun limequat (lime x kumquat), but no limes. Must shop this spring, oink oink.

Take care,
Grant

Thanks for the feedback! Good thing I don't have to be concerned as it produced some good fruit this past year...thanks again!

I agree about older leaves, but I think they may have been helped to their final demise by a little cold weather? Lime is the most frost sensitive citrus. It doesn't take much to yellow it.
