rootgrow™ 150g – Mycorrhizal Fungi for Stronger Root Establishment
Our rootgrow™ 150g pack is a simple but highly effective planting aid designed to help trees, hedging, shrubs, climbers, grasses, and ornamental plants establish faster and grow stronger. Containing natural mycorrhizal fungi , rootgrow™ works by forming a secondary root system around the plant’s roots, dramatically improving nutrient and water uptake. Suitable for use with bare root, rootball, and pot grown plants , the 150g pack can treat approximately 15–25 bare root plants , several rootball plants, or up to 15 x 2L pots depending on plant size. One application helps support healthier establishment and long-term growth for the lifetime of the plant.
rootgrow™ 150g – Natural Root Support for Trees, Hedging & Shrubs
Our
rootgrow™ 150g pack is a professional-grade planting additive designed to improve root establishment and long-term plant health. Containing natural
mycorrhizal fungi, rootgrow™ forms a beneficial relationship with plant roots, creating an expanded underground root network that significantly improves water and nutrient uptake.
Perfect for use across our range of
bare root hedging, rootball plants, pot grown trees, pleached trees, topiary, climbers, grasses, and ornamental shrubs, rootgrow™ helps plants establish faster while reducing transplant stress after planting.
How rootgrow™ Works
Mycorrhizal fungi naturally occur in healthy soils and attach themselves to plant roots, effectively extending the root system far beyond what the plant could achieve on its own.
This helps plants:
• Improve nutrient uptake
• Increase water absorption
• Establish roots more quickly
• Reduce transplant shock
• Improve resilience during dry weather
Once established, the fungi continue working with the plant for its entire lifetime.
Ideal for Hedging, Trees & Larger Planting Projects
At Harrod Outdoors, we highly recommend rootgrow™ for:
• Bare root hedging projects
• Rootball hedging and trees
• Pleached trees
• Topiary plants
• Ornamental and screening trees
• Climbers and ornamental grasses
The 150g pack is ideal for medium-sized planting projects and larger specimen plants where strong root establishment is especially important.
Coverage & Usage
The 150g pack provides excellent coverage for a range of planting applications and is ideal for gardeners, landscapers, and trade projects alike.
Always apply rootgrow™ directly onto the root system during planting to ensure successful colonisation of the fungi.
Natural & Environmentally Friendly
rootgrow™ is completely natural and plant friendly, making it suitable for ornamental gardens, edible planting areas, landscaping projects, and wildlife-friendly spaces.
Unlike artificial feeds or liquid stimulants, rootgrow™ creates a long-term biological support system beneath the soil, helping plants naturally access more moisture and nutrients over time.
Application Instructions
For bare root and rootball plants, sprinkle rootgrow™ directly into the planting hole so it comes into contact with the roots. For pot grown plants, apply around the rootball before backfilling with soil.
The fungi must physically touch the roots to work effectively.
Suitability & Limitations
rootgrow™ is suitable for most trees, hedging plants, shrubs, flowering plants, grasses, climbers, and edibles.
Please note that rootgrow™ is
not suitable for:
• Brassicas
• Rhododendrons
• Azaleas
• Heathers
• Cranberries
• Blueberries
For these varieties,
rootgrow™ Ericoid should be used instead (except Brassicas).
Summary
rootgrow™ 150g is a natural, easy-to-use planting additive that supports faster establishment, healthier root systems, and stronger long-term growth. Ideal for hedging, trees, shrubs, climbers, and ornamental planting, it provides a simple way to improve planting success naturally.
