Thank You Everyone!! Mangomongo, Guayaba, Jani & edzone9!! Especially for organic suggestions! I will definitely try Jani & edzone9 suggestion first as it's also a free option lol. (& some of the soot was already peeling off). Next option will be neem oil as mangomongo & Guayaba suggested. Might need it for my LemonMeringue also.
Mangomongo I know how you feel about making your own mix too! I've read up on not letting mango fruit the 1st Year for a better tree & harvest the following time & I have a Rosa mango flowering for the first time & I'm waiting until there's pea sized fruit before I cut them. Also good luck with your mango trees this season too! I can't wait to see Squam256's orchard in person as he is local & not to mention how I found his farm recently before joining here (& has with the one of the largest varieties of cultivars too). His instagram has my mango addiction on overdrive impatiently waiting for mango season haha
