Westland Sulphate of Iron 1.5kg

Why Use

Sulphate of iron makes soil more acidic, enabling special acid-loving plants to take up the nutrients they need for healthy growth and development.

For these special plants, if soils become too alkaline they suffer severe deficiencies when essential nutrients such as iron become unavailable. Sulphate of iron enriches and unlocks these nutrients from the soil. Works best for rhododendrons, camellias, azaleas and hydrangeas.

What to Expect

Sulphate of Iron will create the right conditions for healthy plant growth, keeping leaves green and healthy and preventing leaf yellowing.

For best results: When planting out your trees and shrubs use a dedicated compost to give your plants the very best start.

When to Use

Sulphate of Iron can be applied every 4-6 weeks during the growing season from March to the end of August. Granules should be worked into the soil. During dry weather, water thoroughly before and after application.

How to Use

One handful of Sulphate of Iron is approximately 35g (1¼ oz).

You can apply Sulphate of Iron every 4-6 weeks to maintain the best soil pH for ericaceous plants.

Trees and shrubs
