Organic Garden Mulch

Transform Your Garden with Organic Mineralised Straw Mulch

Give your plants the best start with this premium mineralised straw mulch. Specially crafted from wheat straw, this organic mulch is designed to boost plant health, suppress weeds, and improve soil structure across all types of gardens.

• Nutrient-Rich Formula: The mineralisation process enriches the straw with essential nutrients, feeding your flowers, shrubs, and vegetables while supporting stronger root systems.
• Weed Control: Apply a layer around your plants to block light from reaching weed seeds—reducing unwanted growth without harsh chemicals.
• Sustained Benefits: With a lifespan of up to two years, this mulch reduces the need for frequent reapplication and keeps your garden looking neat.
• Moisture Management: The straw acts as a natural barrier, locking in soil moisture so your plants stay hydrated during dry spells.
• Soil Health: As the mulch breaks down, it adds organic matter to the soil—improving texture and fertility over time.

How to Use in Your Garden

• Best Application Time: Apply in spring or autumn after planting or when beds are freshly weeded.
• Coverage: Spread a 3–5cm layer around established plants, leaving space around stems to prevent rot.
• Compatibility: Ideal for flower borders, vegetable plots, fruit bushes, roses, and ornamental beds.
• Care Tips: Check mulch depth annually and top up if needed. Water well before applying if soil is dry.
