We transplanted 50 good looking aloes, they were healthy, after 5 or 6 days they start to turn white and rot/die, I believe it is a fungus, so far we have use a peroxide based fungicide with natural oils. Any ideas? The soils is very sandy and is not soaking wet, but moist, also very alkaline, about 9. Today I will put phosphoric acid in the irrigation water to balance the soil PH to 6.5 very bad soil quality so we put vermicompost to better it. Will they die? Should I cut the fallen leaves? We live in Cabo San Lucas, Baja Sur, Mexico, Aloe plants here grow all year long. Thank you much for your input.
