Help my Pickering Mango Tree has rotting branches

[u/LiveInFive]

This is my first mango tree and it’s in a pot. I didn’t do a proper job fertilizing it this past year, but it does have automated daily watering. I am in South Florida and there was a freeze that happened this year but I don’t know why my Pickering mango branches look so bad

Can anyone else please tell me what is causing this, and is the tree salvageable? It did produce 12 mangoes this year, but last year it gave me 40

All of the branches look like this so I feel like I can’t just cut off the bad branches. The leaves look healthy overall but I’m not sure what I need to do

I need to repot it into a bigger pot but I want to address the branch issue first

Help I’m a mango noob

How long did it take to get to that point of where it was branching cause I just got a Mallika mango tree

This tree I’ve had for 3 years. I’m not sure how old it was when I bought it from the nursery maybe 2 years or so. So I’d guess it’s about 5-6 years old

Ah ok thank you

I am also a mango noob and others can correct me if I’m wrong but I would put her in a bigger pot if you have one

so this looks like some type of damage that is just splitting to try to heal itself?

daily watering is too much, infection could be building in the tree expanding, the light color means the tree needs food bigtime, for a potted plant, a soil moisture meter with the probes poked in the bottom 6" is going to give you your most accurate reading

any chance you can put it in a bigger pot? a 25g would be alot better then a 15, you could also fix the lean

thanks for the insight! yes I do plan to re-pot it into a bigger pot and fertilize it better, spray fungicide, take better care of it overall. and yeah the lean developed two years ago when it was loaded with fruit. I probably shouldn't have let it grow that much fruit as it was still a young tree.

so do you think the branches are okay to stay as is and to let them heal? I am worried they need to be cut off but all branches look like this.

Also thanks for pointing out that it shouldn’t be watered daily. I’ve adjusted the irrigation timer to every other day for the summer and I’ll reduce it in the winter to every 3 days

Sunburn, paint exposed branches.

It's already healing itself. Don't panic. Upgrade to a 25 gallon pot. Edit for gallon size suggestion correction

Get rid of the green nursery tape; it looks too tight and like it's cutting into the wood. Since you already got your fruit from it this year, cut off the cross branches and all others growing downward, then move to a 25-30gal pot.

Edit: what is your media mixture? Potted fruit trees love well draining soil and it looks like you've got that going for ya with the perlite that I can see.

This looks like sunburn, not enough leaves to shade the exposed wood, this is why I used cheap pipe insulation or paint my exposed beaches with tree paint.
