>>>I have Bannana Trees & Elephant Ear Plants around my yard. The first few
years they grew real good & quite fast. Now, after about 5 years they are
not a sporty lookin & kinda pale green <<<
Both plants require an inordinate amount of nitrogen in order to thrive. It
sounds as though your plants have exhausted the amount native to the soil
and needs replenishment with fish emulsion fertilizer or straight nitrogen
fertilizer. Manure is a good source.
