20 Best Liquid Iron For Lawns (2023 Updated)

Liquid iron for lawns is an iron supplement that is applied to the lawn to promote green growth. Iron is an essential element for plant growth, but it is often lacking in soils, especially those that are high in alkalinity.

Applying liquid iron to the lawn helps to correct this imbalance and promote green, healthy growth.

Directions How to Use: For best results, apply to moist soil or after watering. Apply every 2 to 4 weeks, as needed, as a supplement to your regular fertilizer program. When to apply: Anytime after the danger of frost has passed and the soil is not still frozen from winter. In Florida: Do not apply to lawns in North Florida during winter months.
