How to use rootgrow to help your tree or hedge establish

You have put a lot of time and thought into which tree or shrub you want, how big it’s going to get and where you are going to put it, so don’t miss out on giving it the best possible start in its new carefully selected home. This is our guide on how to use Rootgrow with container grown plants and bare root hedging.


Rootgrow contains mycorrhizal fungi which is a completely natural and plant friendly product. Its great for use on flowering plants, trees or shrubs. Within as little as four weeks the fungi will have created an entire secondary root system that will increase nutrient and water uptake helping to support the tree for the rest if it’s lifetime.
Using Rootgrow is easy, sprinkle into the bottom of the planting hole, making sure that the granules are in direct contact with the roots. In just weeks the fungi will have attached themselves and grown out into the surrounding soil.


  • Excellent water and nutrient uptake and enhanced natural vigour
  • Increased abundance of flowers and heavier cropping
  • Plants need less synthetic fertiliser and are able to survive
  • Bolsters replanting resilience
