Vitax Yellow Sulphur Powder for Powdery Mildew

Yellow Sulphur provides an essential secondary nutrient that all plants need for healthy growth. It is a key part of many amino acids and supports efficient protein production, which is vital for strong development. With modern pollution controls reducing natural sulphur in the atmosphere, many soils in the UK are now lacking this nutrient.

Using this sulphur powder for soil helps restore balance and keep plants productive and resilient. You can also try our organic seaweed plant food to which promotes growth and resilience with natural minerals.

Key Features of Sulphur Powder For Soil

• Supplies sulphur powder for soil to support protein production and healthy growth
• Helps prevent yellowing of young leaves and improves plant strength
• Reduces susceptibility to powdery mildew and black spot on roses
• Conditions soil for acid loving plants such as azalea rhododendron heather and camellia
• Can neutralise hard water when plants are grown in tubs and planters

Why Add Sulphur For Plants

As cleaner air has reduced sulphur deposition, some soils now require extra sulphur to keep plants healthy. Deficiency is shown as yellowing between the veins and around the edges of the youngest leaves. Lack of sulphur can also increase susceptibility to diseases such as powdery mildew and black spot.

How To Use Sulphur Powder In The Garden

Sulphur can be applied as a tonic either directly onto foliage or around the base of plants. Shake the pack before use and remove the cap. Squeeze the pack gently while pointing slightly downwards to discharge the powder and ensure even coverage of the surface being treated.
