Can you tel me what is wrong with my lime tree. Like in the picture, a couple shoots of the tree are turning brown and are dying. Should I cut the dead parts off of the tree?

Also. A closer picture. Did you rouff up or open up root ball before you planted ? If it was root bound ! You may half to dig it up and untangle roots. Do that under water if possible. They also need frequent shallow watering , YEAR ROUND !
Also...make sure. To cut off an suckers growing below graph.
Anything thats dead, scrape it to be sure, should be cut off, as it will rob the tree. Some citrus fertilizer wouldnt hurt either.
Get back with more info. Please ๐Ÿ˜๐Ÿ˜Ž๐Ÿ˜Ž๐Ÿ˜Ž
Anything i say, could be misrepresented, or wrong.

This is in New Orleans, Louisiana. The tree was planted about five months ago and was always doing great until recently one of the main shoots went completely brown and lost leaves. I don't know if something got to it or if it caught a disease. You think I should cut off one of the main shoots that seems to be dying which is about half of the tree? I attached a better picture.

Hi Jnt, did you by any chance have a freeze or a night of heavy frost in January? That could explain the partial die-back. A layer of mulch around the tree would both help keep the roots an even temperature, including protecting from cold, and help to keep weeds from growing in the root zone. Don't forget that any tree will have roots extending out well past where the branches reach (known as the "drip line") and citrus have a lot of fine feeder roots near the surface so any weeds in about a 4ft. wide circle around that tree are competing with it for nutrients.

Before you cut off any twigs, just scrape the bark off a tiny bit with your thumbnail and see if there is green under the bark. If there is, the twig is still alive and you should keep every living twig on a tree that small. By all means prune off anything that is dead.

Philip is right, some citrus fertilizer would be good but I'd wait to apply any fertilizer until the last of the cold weather is gone and also until you're sure the tree is no longer stressed (no more dying branches). A stressed plant doesn't need fertilizer and it would do more harm than good. When you see new growth starting, that is the time.

Just do be sure to water well, because I don't know about you but here in Florida we've had a terribly dry winter. Again, be aware of watering the whole area around the tree, where all those feeder roots are, not just near the trunk.

Yes there was a freeze but none of my other citrus trees were affected.

Little trees are more vulnerable, and limes are notoriously more tender than other citrus. Mulch that baby, and throw a blankie over it if there's any more cold nights. Just make sure the mulch doesn't sit against the trunk, keep it a couple of inches away.
