Hello,
I live in the Caribbean. My 2 jackfruit trees (roughly 2 years old) are both dying. I was away for a month, and when I came back I noticed lots of holes on all of the leaves (picture attached). Afterwards, I also noticed that some leaves were burnt (black around the edges). Now all the leaves are falling

I try to water them once a day, at sunset, if it didn't rain. Recently I added a mix of manure and soil at the base, and covered it with dry leaves, as I thought tat perhaps the burnt leaves meant that there wasn't enough moisture, and it needed more nutrients. It doesn't seem to help.
I don't know what else to do. Could anyone help please? I wonder if the trees were attacked by some pests, but not idea what as I didn't see anything on the trees, and what to do to avoid this.
Thanks so much!
