However, the average precipitation of 25-26 inches is erratic and very unevenly distributed throughout the year. Supplemental irrigation is necessary. As such the soils are deep and alluvial. Texture ranges from heavy clay to silty clay loam. My specific soils are the latter.
Drainage is moderately good.
However, for optimum banana growth the soils need to be worked and amended. All my plants are grown outside - there is no greenhouse. There is no muriate of potash or ammonium sulfate in the Peters solution. Those two compounds can raise the salts and pH of the soil. Once in the ground I use exclusively organic techniques preferring to let the earthworms do the work.
