Thrives Guaranteed or We Fix It

• Iron Guard Plus contains chelated iron that remains available to plants even in alkaline Australian soils. This advanced formulation prevents nutrient lockout common with standard iron supplements.
• Suitable for all plant types including acid-loving natives, fruit trees, roses, and lawn grasses. The 2.5L size provides excellent value for treating medium to large gardens.
• Fast-acting formula shows visible greening results within 7-14 days of application. Regular use maintains healthy foliage colour and improves overall plant vigour and disease resistance.

• Store Iron Guard Plus in a cool, dry place away from direct sunlight and extreme temperatures. Shake well before each use to ensure even distribution of nutrients.
• Apply every 4-6 weeks during growing season or as needed when yellowing appears. Reduce to monthly applications for maintenance feeding.
• Always wear gloves and eye protection when handling concentrated formula. Rinse immediately if product contacts skin or eyes.
• Apply to moist soil and water in thoroughly after soil drenching. For foliar feeding, spray until leaves are wet but not dripping.
• Best results occur when soil pH is between 6.0-7.5. Test soil annually and adjust pH if needed for optimal nutrient availability.

• Apply Iron Guard Plus during cooler morning or evening hours to prevent leaf scorch. Water plants thoroughly before and after application for best nutrient uptake.
• Mix with water according to label rates and apply as soil drench or foliar spray. Foliar application provides faster results for severely deficient plants.
• Use regularly during active growing seasons when plants have highest nutrient demands. Reduce frequency during winter dormancy periods.

• Iron deficiency showing as yellowing leaves with green veins requires immediate application of Iron Guard Plus. Apply every 2-4 weeks until foliage returns to healthy green colour.
• Nutrient lockout in alkaline soils prevents iron uptake even when present. Iron Guard Plus chelated formula bypasses this issue and delivers available iron directly to plants.
• Over-application can cause leaf burn or nutrient imbalance. Always dilute according to label directions and avoid applying in extreme heat or drought stress.

How often should I water Iron Guard Plus 2.5 L?

Apply Iron Guard Plus 2.5L every 4-6 weeks during active growing season. Increase frequency to every 2-3 weeks for severely iron-deficient plants showing yellowing foliage. Reduce applications during winter when plant growth slows and nutrient demands decrease.

Is Iron Guard Plus 2.5 L safe for pets?

How fast does Iron Guard Plus 2.5 L grow?

Iron Guard Plus 2.5L provides visible results within 7-14 days of application. New foliage emerges with healthy green colour while existing yellowed leaves gradually improve. Results speed depends on severity of deficiency, soil conditions, and plant health status at treatment time.

Does Iron Guard Plus 2.5 L prefer full sun or shade?

Why is my Iron Guard Plus 2.5 L dying?
