Superphosphate Fertiliser 25kg

Superphosphate Fertiliser 25kg is your go-to phosphate boost for confident root development. This readily available source of phosphorus feeds roots where they matter most, helping plants establish quickly and thrive from the ground up.

Why phosphorus matters for healthy roots

Phosphorus is a cornerstone nutrient for root growth and energy transfer within plants. By delivering accessible phosphate directly to the root zone, this fertiliser supports stronger, more resilient root systems. The result is sturdier initial growth, better uptake of other nutrients, and a foundation for healthier crops and ornamentals.

Key benefits you’ll notice

• Supports strong root development in root vegetables such as carrots, beets, and potatoes, improving establishment and vigor
• Encourages quicker establishment when planting shrubs, hedges, or other ornamentals
• Promotes healthier, earlier crop maturity in vegetable plantings, helping you get harvests sooner
• 25kg bag provides a practical, long-lasting supply for beds, borders, and larger planting projects
• Readily available phosphate that plants can uptake efficiently, supporting better nutrient use across the growing season

How to use

Apply at planting time to maximise root-zone availability. For garden beds and borders, lightly work the fertiliser into the topsoil before sowing or transplanting. In raised beds or containers, sprinkle evenly around the root zone or mix into the top 5–10 cm of soil, then water well to begin nutrient transfer. Use as part of your seasonal feeding plan, following the product label directions and adjusting for soil conditions and crop needs.

Who should use this

Ideal for home gardeners and allotments aiming for stronger roots, quicker establishment, and earlier harvests. Especially beneficial when starting root crops or introducing shrubs and ornamental plants into new or existing planting schemes.

Why this phosphate fertiliser stands out

Designed as a ready-to-use, readily available source of phosphate, it delivers phosphorus when roots are most hungry, supporting efficient nutrient uptake and robust early growth. The 25kg format is economical for larger projects, reducing the frequency of reordering while keeping your plants well-fed throughout the season.
