Is my Kumquat tree dying?? :(
Hi, I bought a kumquat tree a few months ago, and it was growing pretty good for a bit, but it looks like it's dying now. It has some new growth on it from earlier and you can tell from the lighter colored leaves, but a lot of the branches seem to be drying up and dying and the entire tree is looking a lot more bare than it used to be.
Here's the link to 2 pictures
It's a bit hard to see since there's other plants/trees behind it. But in the close-up picture you can see the ends (well the top 1/3 to 1/2) of the branches are brown and look like they're dead. They snap off too. I've only been watering it about once a week.
Please let me know if this is normal or what I should do to 'revive' the tree. Thank you.
