What is Sulphate of Iron?
Sulphate of Iron is a naturally occurring mineral that serves multiple purposes in gardening.

Types of Sulphate of Iron Products
There are generally two forms of Sulphate of Iron available:
- Granular Form: I found this easy to spread using a hand or broadcast spreader. It dissolves slowly and provides a sustained release of iron.
- Liquid Form: This was my choice for quick applications. It’s easy to mix with water and spray directly onto the affected areas.
How to Apply Sulphate of Iron
My experience with application has taught me a few best practices:
- Timing: I usually apply it during the growing season, preferably in the spring or early fall.
- Preparation: I ensure to mow my lawn first and water it lightly to avoid burning the grass.
- Application Rate: Following the instructions on the package is crucial; I typically use about 100 grams per square meter for effective results.
Safety Precautions
While using Sulphate of Iron, I make sure to wear gloves and a mask to avoid inhaling dust or getting it on my skin. Keeping pets and children away during application is also a priority for me.
