I've got mine in the ground, it's a little shorter than yours but the leader only has a few short branches at the base and a couple at the top. So less bushy than yours. The small branches at the bottom seem to be dying off, a bit similar to what I see on yours. No idea what's causing it but it has me concerned. I'm hoping that as the season changes (it's still winter here now) it'll put on some new growth. I'm hoping it's just normal for the plant to get rid of lower growth/branches. Maybe someone knows for sure and will confirm.

I have some citrus trees that have had some die off on certain branches and the rest of the tree is fine. Maybe this is normal? From looking at the pictures, the tree looks healthy so maybe there is nothing to worry about. I have read that finger limes don't need as much fussing over as regular citrus when it comes to fertilizing. There is a finger lime group on FB which you may consider joining because this variety is relatively new here in the US.

Dying off is not normal for any tree. The branch part. Leaf loss can be and it can also be the product of a bad root system. I would get to the root of the problem because your tree is trying to tell you something.

My tree looked like the one in pic 1. I trimmed the bottom branches and it looks much better. I have not had a dead branch as shown in pic 3

"Dying off is not normal for any tree. The branch part."

That's not altogether true. Quite a few trees will drop lower limbs as part of the growth process.

I have had some small limbs die back and go no further which is why I said what I did.

Yeah, I kind of understand .

I was meaning it's not normal for my potted trees. The only time that ever happens on my trees is if the roots are under some sort of stress. And with that, I quickly become concerned and fix it.

I never accept that as being normal. I was a landscaper for over 20 years and even in if in ground trees starting loosing branches, twigs, we were concerned. It's 'usually' a sign of something not right.

Tyler, it's good to see you are concerned about losing branches and twigs at any time, especially on a young potted one. Tyler, I am also taking into account the smaller tress to left of that one. It seems they too have a few lost branches. I would make sure your soil is doing a good job.

I do not have this plant. However, I noticed the way it looks it reminded me of several of my rose bushes when they are attacked by chilli thrips.... I googled it and citrus is attacked and a host for the C. thrips.... Not saying this is your problem, maybe you could google it too or ask someone in your area that has C. thrips..... C Thrips can be controlled with spinosad. It is on contact, not a systemic.... Spray in the evenings... if C. Thrips you will have to repeat. Once you have older leaves (at least of roses) they leave them alone. They like new growth, and once it cools down some they will also not be so active.

With my fingerlime trees, its usually because the roots either are too wet or too dry. Either one of those conditions will cause die back on the tips of the branches. I grow both the green and the red fingerlimes.

I had a lot of branch die back on my Aus Finger Lime when I let it get too wet. They do NOT like wet feet, well draining soil is a must. Even in a pot, I do not mulch mine. I also keep it out of the hot afternoon sun. It's often found as an understory tree (although can be cultivated in full sun), but this summer's sun in SoCal was too much for it. I just had it recovering from the over watering when I moved it into the full sun. Die back again... Surprised the poor thing is still alive, but it's recovered nicely and leafed out again.
