SumaGrow does very well during heat waves and drought conditions. In this trial, the drought did not affect the yield on the SumaGrow plots, however, the control plot yield was very low. It was a fair trial, however, the yield increase was so great that we are going to mention. You will have to read the report your self to see the yield increase.
Notice how you can see the soil in the control plots while the SumaGrow plots are so dense, you cannot see the soil.
