Ferrous Sulphate Fertilizer

Ferrous Sulphate (آئرن سلفیٹ) is a fast-acting iron supplement that treats iron deficiency (chlorosis) in plants — one of the most common causes of yellowing leaves in Pakistan’s alkaline soils and hard water areas. It helps restore deep green color, improves chlorophyll production, and encourages healthy growth.

Use it for vegetables, roses, citrus, guava, lawn grass, and acid-loving plants like hibiscus and blueberries. Particularly useful in Punjab’s high pH soil and urban gardens affected by poor soil quality.

Benefits:

• Fixes Yellow Leaves (Chlorosis): Treats interveinal yellowing caused by iron deficiency
• Supports Greener Growth: Boosts chlorophyll and helps plants absorb other nutrients
• Improves Soil pH: Slightly acidifies alkaline soils, improving nutrient availability
• Versatile Use: Suitable for pots, lawns, garden beds, and fruit trees
• Ideal for Pakistani Soils: Especially helpful in areas with high pH or hard water

How to Use Ferrous Sulphate:

1. For Potted Plants (8–12 inch):

• Mix 1 tsp (5g) in 1 liter of water
  
• Apply to soil directly, avoiding leaves

2. For Garden Beds:

• Mix 50–100g per 10 sqm into soil and water thoroughly

3. For Lawns:

• Mix 100g in 10 liters of water and spray evenly over the grass

4. For Citrus, Guava, Roses (Soil Drench):

• Mix 1–2 tsp per liter of water and pour near the root zone
  
• Apply every 15–20 days during active growth

⚠️ Precautions:

• Do not spray directly on leaves — this is a soil application product
• Wear gloves when mixing
• Store in a dry place away from children and pets

FAQs – Iron Fertilizer for Yellow Leaves

What are signs of iron deficiency?
Leaves turn yellow with green veins, especially on new growth. Common in tomatoes, guava, citrus, and flowering plants.

Can I use it on edible plants like chillies or spinach?
Yes — just apply to soil and wait 5–7 days before harvesting. Always wash produce thoroughly.

Can I spray it on leaves?
No. Ferrous sulphate is best used as a soil drench. Foliar application may burn sensitive leaves unless diluted heavily.

How often should I apply?
Every 15–20 days during active growth or when symptoms appear.

Can I mix this with neem oil or liquid fertilizers?
Avoid mixing with acidic foliar sprays or neem oil. Apply separately with a 3–5 day gap.

💡 Tip for Gardeners:

Use ferrous sulphate with compost or organic matter to speed recovery in iron-deficient soil. If you're growing guava, citrus, spinach, or roses in alkaline soil, this iron booster can make a huge difference in leaf health.
