Why Use Epsom Salts?

Magnesium is an essential nutrient that plays a key role in chlorophyll production, helping plants produce healthy green leaves and strong growth. A lack of magnesium can lead to yellowing foliage, particularly in heavy-feeding crops such as tomatoes. Regular use helps maintain healthy plants throughout the growing season.

When to Apply

For the best results:

• Apply every 4 to 6 weeks during the growing season.
• Use from March through to the end of August.
• Apply to moist soil or water thoroughly before and after use during dry weather.
• Avoid applying in hot, bright sunshine to help prevent leaf scorch when spraying foliage.

Application Rates

Approximate Measure

One handful is approximately 35g.

Trees & Shrubs

Scatter 20g per square metre around the base of established plants. Lightly work the granules into the soil without disturbing roots, then water thoroughly.

For a foliar feed, dissolve 35g in 4.5 litres of water and spray evenly onto the leaves using a fine mist. Avoid spraying during hot, sunny weather or when plants are suffering from drought stress.

Flowers & Vegetables

Apply 20g per square metre around plants and gently work into the soil surface. Keep granules away from leaves and stems before watering well.

Soil Improvement

For general soil conditioning, spread 20g per square metre over the soil and incorporate it into the surface before watering.
