I moved into a home with very overgrown but mature trees just over a year ago. We hired a professional to trim the backyard mango and ackee tree since both are taller than my one story South Florida home (25ft +?) On the side of the house, I started to fertilize and prune a neglected citrus tree (I still can't identify), an avocado tree whose fruit I didn't even want to eat - symptoms of Anthracnose and other deep and brown "pitting" and a smaller mango tree that never fruited but is large enough that it should. We also had the professionals prune the an oak and mahagony tree out front. Since I'm right off a freshwater canal, I tried to limit the use of harsh chemicals so I treated all the trees with neem and horticultural soap. I could see the thrips everywhere and the leafminers did its damage on the citrus tree. As for the mango, it was an all you can eat buffet but despite being so close, I never noticed the same type of leave damage on the other trees. I figured it was coming from the overgrown bougainvillea who merged with some type of holly (pretty cool actually the way the trunks became "one"). So my husband and I gutted and removed that and hired Aptive, an environmental friendlier service though I did use standard fertilizer. Everything seemed to be going well but around May I saw some serious changes with my mango tree. It was amazing to see how something could create "gorges". I noticed a substantial amount of ants on it, in the roots of my banana trees and essentially all over. Soon I noticed the same gouging though my less significantly on my ackee. By July, my avocado had a deep "chip" that was not cause by the lawn mower and now my mahagony to me, looked bad too. After harvesting my mango, I became super diligent with fertilizing, traditional lawn ant insect treatments and home applications of Captain Jack's Deadbug brew. My citrus tree doesn't look pretty but it was growing nicely, I only applied organic treatments on the avocado and it looked the best it ever has according to neighbors and gave me plentiful and better looking fruit. The wound is healing nicely and quickly. The small mango tree, I think needs to be cut because it is "bleeding" and there are wounds/cankers where there wasn't. With Hurricane Irma I lost half of my mango's canopy out back. I took the opportunity to see the condition of the branches. Most were healthy looking but some of the smaller branches revealed holes and boring. I'm afraid I'm going to lose them all if I can't figure this out. The previous tree guy won't even come out and diagnose. I've said alot but I thought after reading, the history of the trees and treatments I did myself were important to note. The timeline too as it started in May and seems to have a devasting cascading effect across the entire lot.
