Thank you for the info.
Am not new to growing trees, pruning etc. I have a small collection of healthy trees around the sickly LZ : Nam Doc Mai, Kent, Mun Kun Si, Carry, Sapodilla, Avocado, Mamey Zapote, Caimito, Lychee. But I must admit I have never pruned a mango down to the bare stump. The LZ, however, it is turning into a challenge. Am going to try pruning it and see if the new growth comes out healthier.
Thanks!
