South Africa Organic Citrus Grower Improves Tree Survival Rate Using SumaGrow

A South African organic citrus farmer improved his tree survival rate to almost 100% (up from 50%) after applying SumaGrow, three years after replanting new organic citrus trees into “very old citrus soil”.

Due to organic growing restrictions on the use of chemical poisons/fertilizers, this farmer’s previous optimal survival rate was around 50%.  The citrus trees from the block treated with SumaGrow are also carrying many more oranges versus the control.

Along with the improved survival rate, there is also a remarkable difference visible with naked eye. The farmer (based in the Sunday’s River Valley) invited us to bring any serious Citrus farmer to “come and see for themselves”.
