Precautions for using ferrous sulfate on chrysanthemums
When watering chrysanthemums with ferrous sulfate during maintenance, it should be noted that ferrous sulfate is not a fertilizer but a regulator. It can only be used to balance the soil pH and supplement the microelement iron ions. Iron is second only to the three elements "nitrogen, phosphorus, and potassium" when fertilizing flowers. Therefore, it is recommended not to use it in the first year of caring for chrysanthemums.
