Yes. Nutra Greensand mainly supplies potassium and trace minerals, so it’s often applied alongside nitrogen- or phosphorus-based fertilizers. It doesn’t trigger unwanted chemical reactions and can even improve the uptake of other nutrients.
Usually once per year — early spring or fall. Glauconite releases nutrients slowly, so frequent re-application is not required.
Yes. It’s a 100 % natural mineral with no toxic additives. Keep the bag out of reach and avoid inhaling dust while handling.
Absolutely. Mix 2–3 tablespoons per 5 L of potting mix when planting or repotting to improve structure and supply slow-release potassium.
It’s virtually impossible. The mineral releases nutrients gradually and won’t burn roots. Excess granules stay in the soil and are absorbed over time without harm.
