crazy banana

Interesting video.
I have used Micro Hume in combination with Liquid Kelp and/or Fish emulsion in the past and it has perked up a plant, but now I have way too many plants with a p-stem height between 10' to 15' plus leaf canopy even taller, so foliar spraying is not really practical. Micronutrients will be best absorbed by banana plants if the soil pH is between 6.5 and 7.5 .
Work on optimizing your soils pH and no foliar spray is necessary as a good fertilizer like Richard's" Fruit Fuel" for example, will be available to the plant through a healthy root system.
