Proverde Iron Boost
Iron Boost – Chelated Iron EDDHA 6%
Restore Deep Green Leaves and Correct Iron Chlorosis
ProVerde Garden Iron Boost is a premium Chelated Iron EDDHA 6% fertiliser specially formulated to rapidly correct iron deficiency (chlorosis) in ornamental plants, fruit trees, vegetables, vines and many other crops.
Iron is one of the essential micronutrients required for healthy plant development. When plants cannot absorb enough iron, they lose their rich green colour and develop pale yellow leaves with green veins—a condition known as iron chlorosis. Left untreated, iron deficiency reduces photosynthesis, weakens plant growth, lowers flowering and fruit production, and can eventually lead to severe decline.
Iron Boost supplies highly available iron in the form of EDDHA chelate, the most stable and effective iron chelate for alkaline and calcareous soils. Unlike ordinary iron sulphate products that quickly become unavailable in high-pH soils, EDDHA keeps iron soluble and readily available for plant uptake, ensuring long-lasting results.
Whether you grow citrus trees, roses, vegetables, grapevines or ornamental shrubs, Iron Boost helps restore vigorous growth and vibrant green foliage.

What is Iron Chlorosis?
Iron chlorosis occurs when plants are unable to absorb sufficient iron from the soil, even when iron is present.
The most common symptoms include:
- Young leaves turning pale yellow while veins remain dark green.
- General yellowing between the veins (interveinal chlorosis).
- Reduced plant vigour.
- Poor flowering and fruit production.
- Smaller leaves and slower growth.
- Severe deficiencies may cause leaves to become almost white with brown scorched edges.
Iron deficiency is especially common in:
- Alkaline soils
- Limestone (calcareous) soils
- High pH growing media
- Poorly drained soils
- Overwatered plants
Iron Boost is specifically formulated to overcome these conditions.

How Iron Boost Works
Iron is essential for chlorophyll production—the pigment responsible for green leaves and efficient photosynthesis.
Although many soils contain iron, plants growing in alkaline conditions often cannot absorb it because it becomes chemically locked in the soil.
The EDDHA chelate surrounds each iron molecule, protecting it from becoming unavailable and allowing plant roots to absorb it efficiently. This provides a reliable source of iron even in difficult soil conditions where other iron fertilisers fail.
Application Instructions
Iron Boost is recommended for soil application.
For best results:
- Dissolve the required quantity in water (approximately 10 g per litre).
- Stir continuously until fully dissolved.
- Apply evenly to the soil around the root zone using a coarse, low-pressure watering can or sprayer.
- Lightly incorporate into the top few centimetres of soil where practical.
- Water afterwards if necessary.
Avoid applying directly onto dry foliage unless specifically recommended.
Recommended Dosages
| Crop | Recommended Rate |
|---|---|
| Field crops | 2.0–4.5 kg per hectare |
| Young citrus trees | 400–600 g per 100 m² |
| Mature citrus trees | 150–450 g per tree |
| Citrus maintenance | 80–120 g per tree annually |
| Apples, pears, peaches, almonds, pistachios | 20–100 g per tree |
| Grapes and soft fruit | 600–800 g per 100 m of row |
| Ornamental shrubs | 16–40 g per bush |
| Ornamental plants | 50 g per 10 m² |
Always apply when iron deficiency symptoms first appear or as a preventative treatment where iron deficiency is known to occur.
Do not exceed the recommended application rates.

Frequently Asked Questions
Why are my plant leaves yellow but the veins stay green?
This is one of the classic symptoms of iron chlorosis, where the plant cannot absorb enough available iron. Iron Boost helps restore normal green growth.
Can I use Iron Boost on citrus trees?
Yes. Iron Boost is particularly effective on lemons, oranges, mandarins and other citrus species, especially those growing in alkaline or limestone soils.
Is Iron Boost suitable for potted plants?
Yes. Dissolve the product in water and apply to the potting mix around the roots.
Can I use it with hydroponics?
Yes. Iron Boost can be used as an iron source in hydroponic nutrient solutions and fertigation systems.
How quickly will I see results?
Depending on the severity of the deficiency and growing conditions, plants often begin showing greener new growth within 1–3 weeks. Existing yellow leaves may not fully recover, but new leaves should emerge healthy and green.
