Magnesium Nitrate is a fast-dissolving fertilizer that treats magnesium deficiency and supports green, healthy growth. It delivers two essential nutrients — magnesium (for chlorophyll) and nitrate nitrogen (for strong foliage) — making it perfect for vegetables, herbs, flowering plants, and fruiting crops.
If your older leaves are turning yellow between the veins — especially on tomatoes, chilies, citrus, spinach, or coriander — this is a quick and effective fix. It can be applied to the soil or sprayed directly on leaves for fast visible improvement.
Why Choose Magnesium Nitrate for Plants?
-
Treats Yellowing Leaves Quickly: Corrects magnesium deficiency within days
-
Improves Chlorophyll Production: Promotes deep green, healthy leaves
-
Accelerates Growth: Nitrate nitrogen boosts leafy development and flowering
-
Water-Soluble & Fast-Acting: Absorbs through roots or foliage
-
Safe for Edible Crops: Use on vegetables, fruits, and herbs (pause 7 days before harvest)
How to Use Magnesium Nitrate Fertilizer
For Pots (8–12 inch):
- Mix 1 teaspoon (5g) in 1 liter of water
- Pour into the soil or spray directly on leaves every 10–15 days
For Garden Beds (10 sq m):
- Use 50–100g, either dissolved or dry (followed by watering)
As Foliar Spray:
- Mix 5g per liter and spray on leaves
- Apply early morning or evening to avoid heat stress
⏰ When to Apply
Use during active growth or flowering phase, especially when early signs of magnesium deficiency appear. Avoid spraying during hot hours.
FAQs – Magnesium Nitrate
1. Is this safe for edible plants like spinach, coriander, or mint?
Yes. Just stop applying 7 days before harvest and wash leaves well.
2. Can I use it together with NPK?
Yes — Magnesium Nitrate complements most NPK blends.
3. How long before I see improvement?
You’ll usually notice greener leaves within 3–7 days, especially if applied as a foliar spray.
4. Can I use it for citrus or fruit trees?
Yes — it's great for citrus, guava, mango, and other fruit plants, especially if leaf yellowing is visible.
5. What’s the difference between soil and foliar application?
Soil feeding offers steady nutrient release, while foliar spraying gives faster visible results for magnesium deficiency.
