Do you use Foliar Spray for your Bananas, if so please give you mix formulation. ... If you are using a base fertilizer products, please give links to those so the label can be viewed.


Next question, have you experienced leaf burn while using your spray? If so what concentration was the spray?



I've been using Miracle Grow (24,8,16) mixed per directions for my bananas without any problems. I know there has been comments that Miracle grow killed other user's Bananas, but I haven't seen that if the directions were followed.



For large plants (> 3ft & more than 5 leaves):


Miracle Grow @ 1 Tablespoon/gal => 14.3 grams / gal. which gives in solution, 3.77 g/L (.377% solution). This is NPK of .09-.03-.06 mixed solution. (I'll have to weight a tablespoon of Miracle Grow, but for here I just used the 14.3 g standard weight of a Ts).


This is a very low concentration of NPK. Some foliar spray studies appear to have used N & K from 1% to 3% concentration and did not report any leaf burn. ... Looking at some manufacture products for foliar spray on Bananas their N & K varies from .75% to 1.25% when mixer per their directions.


So my problem/question is what concentration of N will produce leaf burn on Bananas?


My next foliar mix for the Bananas will be increased to a 4.5% concentration (170.55g/gal) of Miracle Grow. This will provide NPK of 1.09-.36-.72. ... The potassium (K) can easily be increased by adding MOP or SOP to the mix.
