500,000+ Rhizopellets planted
boosting survival and growth rates across UK forests
Our 500,000th Rhizopellet was planted in collaboration with The Woodland Trust, and the team in the Outer Hebrides celebrated with us, with a well-deserved selfie.
We’re proud to share that Rhizocore has now delivered over 500,000 Rhizopellets across the UK — a major milestone in our mission to help create stronger, healthier forests that thrive naturally.
This achievement wouldn’t be possible without the forward-thinking customers we've worked with — from national organisations to local community groups, all committed to doing things differently when it comes to woodland creation. Together, we’re not just planting trees — we’re changing how forests are grown, using cutting-edge science and nature working hand-in-hand.
But for us, this isn’t just about numbers. It’s about what’s happening in the ground.
Why Rhizopellets Matter — And Why Now
Today, foresters and landowners are facing unprecedented challenges — from increasing pest pressures and drought to degraded soils and rising planting costs. Yet, despite these challenges, tree planting methods haven’t kept pace with the demands of modern forestry.
This is why Rhizopellets offer a new way forward — an innovative, science-backed solution that eliminates the need for fertilisers, reduces costs, and supports trees in the most critical phase: establishment. Our live mycorrhizal fungi pellets are designed to rebuild the natural underground fungal networks that trees rely on to grow, survive, and thrive — something that’s missing from most modern planting.
Scientific research backs up these results. Mycorrhizal fungi are critical to tree health, supporting nutrient and water uptake, and improving resilience to stressors like drought and poor soils (Smith & Read, 2008). Studies have shown that inoculating trees with site-adapted mycorrhizal fungi can significantly improve early growth and survival, especially on nutrient-poor soils (Kariman et al., 2018). Furthermore, these fungi play a vital role in helping trees tolerate drought, making them essential in the face of climate change (Allen et al., 2003). They also contribute to carbon storage in soils, playing a key role in long-term forest health and climate mitigation (Averill et al., 2014).
Proven Results — Backed by Science and Tested in the Field
At Rhizocore, we know that healthy forests start below ground — and we are committed to ensuring that what we offer is grounded in both research and real-world results.
Across the UK, Rhizopellets are helping trees establish faster, grow stronger, and survive better, and the evidence is compelling:
🌿 Trees planted with Rhizopellets are, on average, 21% taller within the first year, giving them a crucial advantage in those vulnerable early stages.
🌿 Survival rates improve by as much as 23%, meaning fewer failed plantings and reduced need for costly replanting.
🌿 In one of our most telling trials — on a plantation site with heather check, where tree establishment is typically difficult — trees grown with Rhizopellets outpaced even fertiliser-supported trees by up to 6cm, showing that fungi can unlock natural growth in ways fertilisers alone cannot.
These outcomes reflect what a growing body of research tells us — that mycorrhizal fungi are essential for helping trees access water and nutrients, withstand drought, and thrive in nutrient-poor soils. They also play a critical role in improving soil structure and storing carbon, helping to create woodlands that are more resilient to climate challenges and better equipped for the future.
Helping Forests Establish Faster, Grow Stronger, and Last Longer
Establishing healthy trees is about more than just planting — it’s about giving them the best chance to survive, grow, and thrive in the long term. Rhizopellets make this possible by unlocking nutrients in the soil that would otherwise remain out of reach, strengthening roots, and building resilience from day one.
This means trees that grow faster, survive better in drought conditions, and require less maintenance — reducing costs for weeding and beating up. For landowners and managers, this not only improves forest health but maximises return on investment and reduces climate risks, helping ensure that forestry assets deliver long-term value.
Importantly, Rhizopellets help future-proof forests against increasingly volatile conditions, supporting healthier soils and more resilient woodlands — a critical part of how forestry can adapt to the changing climate while meeting the growing demand for biodiversity, carbon capture, and sustainable timber.
