Does anyone know if there is any reason not to use potassium more than twice per year on mature trees?

Proper tip pruning can stimulate mango tree graduating into the fruiting stage of its life ... I will dig up the reference--->>> http://www.aalfs.org/descargas/7.pdf Please read the part " shortening the juvenile period of small trees"
3 years I emailed Richard Campbell at Fairchild about mangoes and he said mulch them and feed them 0-0-50 fertilizer. This is his general recommendation... But they like their mango trees small (condo mangoes) with lots of fruiting. I feed my small young mango trees a good NPK with minors each month except November-January. So I did not listen 100% to Richard Campbell. My three large mango trees ....I actually don't want them too large and crowding out the young ones so I will be feeding them mostly potassium
I have a Keitt and NDM4 that are not blooming at all and they should be... especially the NDM4. If your mango trees are growing so fast and so well then they have just have to to blossom and fruit it is part of the biological order of reproduction. On your largest one or two why not only give them potassium. Mulch them but feed them zero nitrogen. Maybe you are doing this? Try a zero nitrogen diet on them. Maybe your soil is too good. Mangoes need stress to blossom. They can be stressed just by keeping them in a pot and will unnaturally precociously sprout panicales
Since you already have great vegetative growth (leaf and branch growth) then cut off the nitrogen which is the father of vegetative growth.
Potassium Nitrate but you need to live in a subtropical climate. Here is a link that talks about it in Spanish......did your Glenn survive?

I'm scratching my head too. What kind of soil are you working with? Do you have rock close to the surface. Internet say's some of Aruba has clay soil and some of Aruba has a thin topsoil on top of rock.
Year three is the trick how old are these?
More potassium should lead to more bloom and more fruiting for mangoes. Look around the internet. I bought some straight potassium fertilizer. I think it's potassium sulfate and I use it on some trees. You will find internet references to Dr Campbell at Fairchild feeding only potassium to his mango trees. This is probably OK once they reach a decent size but if you want them to grow larger they still need N and P
N ---nitrogen grows leaves and branches
P --- phosphorous grows the roots
K--- potassium grows the blooms and fruits
I have been feeding NPK fertilizer with minor elements and straight potassium to some of my trees
What do you mean shipped to Miami?
I will see if there are any rules regarding shipping a tree from FL to Aruba. If all the rules are on your side of the transaction, I may be able to ship it to you as long as I get paid regardless if Aruba customs seizes it or not.
Noni grows wild here all along the coast. Nobody eats them! Only people with terminal diseases eat them to prolong their lives. I don't put noni on list of edible fruits, consider it a medicinal. It's like voting for soapberry as the worst tasting fruit.
BTW, i've read that the new shoots of noni plants are eaten as a vegetable in Borneo.
Ancient Hawaiians brought noni on their canoe journeys to Hawaii. They used it as a medicinal and as a dye. Interesting that they never used the fruit as a medicinal, as is touted nowadays, only other parts of the plant. I've read that the fruit was only eaten as a famine food. (They didn't like it either!)
