How it works for you

Designed to traditional John Innes No.3 standards, SylvaGrow blends durable particle structure with a steady nutrient release. This peat-free medium stabilizes as roots expand, providing reliable aeration and drainage while keeping moisture accessible during dry spells. The result is healthier, established root systems, better pot stability, and less risk of compaction or nutrient spikes compared with non-specialist mixes.

Practical usage tips

• Prepare a well-drained pot and fill with SylvaGrow John Innes No.3 before planting or re-potting.
• Position plants at the same depth as previous soil; water thoroughly after planting to settle the medium.
• Monitor moisture and avoid waterlogging—the blend balances drainage with moisture retention for container gardens.
• Store in a cool, dry place to maintain the structure between gardening sessions.

Why peat-free matters

Choosing a 100% peat-free John Innes No.3 supports sustainable gardening without compromising performance. Peat extraction impacts biodiversity and habitat health, while SylvaGrow uses renewable materials that still deliver the dependable, traditional container performance you expect from John Innes No.3.
