Hello, im in need of some help. i have a Irwin mago tree,it is a little over 4 feet and skinny, it has direct sunlight all day, and I water it every 3 days. I started to get scales under the leaves and brown spots, I talked to the nursey and they suggested Organocide and soap and treat for ants. I used it 2 times over a 2 week period less then recomended the scales are still there but i have seen a reduction due to the ant probelem but the brown spots got real bad almost burnt looking with some leave getting brown tips too(not sure how to post pics) i Lost about 13 green healthly looking leaves in the second week, i have not used the organocide since. I got the mango tree back in june and have on used Sunniland fruit fert 6-4-6 once.
