I have a quite old mango tree in my garden. It is been there before my birth and I'm 23 now.
We cut and prune the tree (not all of it) whenever it gets too big never had issue but only this time after pruning and cutting and a few weeks of successful twigs and green leaves growth, suddenly a couple of things started to happen that never happened before.
- Red gum started coming out from bark
- Leaves completely wilted in weeks but not falling even now. I manually removed as much of the wilted leaves and twigs to remove burden from tree but a few are still up there as seen in images.
- Bark started cracking and there were some insects inside it. I put some pesticide and now I don't see them in the cracks but the tree is still ill.
I researched and figured it may be verticillium wilt or dieback disease or a mixture of both. What do you think it is after observing the images ? In all these years never got this don't know how my soil got infected that bad. Tree has wilted before due to high temperature few times but all that time leaves fell, we watered it more and it became healthy again.
My last hope is this bud which had a few leaves a while ago though slowly dying but somehow it is still surviving even though it is at the bottom of tree.
Even after all this I have put some soil fertilizer, been watering and I saw this leaf growing just recently at the very bottom of tree where I have never seen a leaf before. What does this mean ? Is there still hope ?
Any help,info or observation is greatly appreciated.
Thanks
