Agricultural Gypsum Applied to soil around trees and watered
The gypsum pellets that I applied to the soil around my fruit and palm trees after watering has turned black. Is this normal if not do I water more or?

Sometimes it can oxidize, but I would only water as needed, when the soil is dry down to about 2 inches it will be time to water. This will prevent infection and keep it healthy.
