is this po pyu kalay salvageable?

Good news: my tiny 6-year old NDM4 is flowering!


Less fantastic news: the adjacent pu pyu kalay tree (also in the ground 6-years) is doing poorly. Any ideas why the trunk is leaking sap all over the place like this?

I've also noticed the root system weakening, and the tree (which is not tiny - the trunk is about 4" in diameter, and it is about 8 feet tall) has begun to lean. We have had virtually no rainfall over the past 12 months, but I have been doing my best to hand water things as much as possible.

Looks salvageable to me. I have a Lemon Zest Mango tree on Florida Turpentine rootstock that has that, not as much as your tree, only a few spots where that sap is coming out. I never found out exactly what it is but I assume it's caused from an imbalance of plant hormones and cold weather.

Do you have any parts of your tree that that is girdled by a label, plant tag? How cold does it get when you are?

My tree is still doing ok considering that Florida Turpentine is not the best rootstock for where I live. How does the top of this tree look?

You could try to in-arch a seedling above the sap area if the tree is no longer growing well.

It's never cold down here, but we have had a VERY dry last 12-18 months. I'm wondering if it's a combination of that and an opportunistic insect infection?

At first, I thought it was a type of borer insect resting the hole causing the sap to come out but upon closer inspection, the sap was coming out of cracks in the bark. I did a quick search and found some articles saying that it could be an imbalance of plant hormones that can lead to uneven expansion of the plant causing the cracks and sap.

Perhaps the uneven amount of water is causing uneven expansion issues with the trunk of your tree?
