rootgrow™ Professional contains pure mycorrhizal fungi supplied in large pack sizes for professional growers or when larger planting projects are undertaken. All rootgrow Professional tubs contain sachets of gel powder to be used on bare-root plants if required and a handy 25ml measuring scoop Suitable for garden designers, landscapers and private individuals with large gardens or planting projects.

• A2.5 litre tub contains enough mycorrhizal fungi to treat  250 x 2 Litre pots or 275-825 bare root whips.
• A 5litre tub contains enough mycorrhizal fungi to treat 500 x 2 Litre pots or 550-1650 bare root whips.

What are mycorrhizal fungi?
Mycorrhizas are beneficial fungi growing in association with plant roots, and exist by taking sugars from plants ‘in exchange’ for moisture and nutrients gathered from the soil by
the fungal strands. The mycorrhizas greatly increase the absorptive area of a plant, acting as extensions to the root system. Phosphorus is often in very short supply in natural soils. When phosphorus is present in insoluble forms it would require a vast root system for a plant to meet its phosphorus requirements unaided. It is therefore thought that mycorrhizas are crucial in gathering this element in uncultivated soils. Phosphorus-rich fertilisers are widely used in cultivated ground and not only reduce the need for this activity but are thought to actually suppress the mycorrhizas. For this reason it is best not to use phosphorous rich fertilisers in conjunction
with mycorrhizal fungi. Neither fungi nor plants could survive in many uncultivated situations without this mutually
beneficial arrangement. Mycorrhizas also seem to confer protection against root diseases.

How do plants benefit?

1. One treatment lasts the entire life of the plant (as the plant grows so does the fungal partner )
2. Reduced mortality ( especially with bare-rooted whips and transplants)
3. Better dought tolerance ( the vast fungal network makes use of all the available moisture )
4. Improved Establishment ( in just 2 – 4 weeks the Mycorrhizal Fungi can increase the active root area by up to 700 times )
5. Better uptake of applied fertilisers ( Mycorrhizal Fungi act like a net, catching nutrients and reducing leaching )
6. Improved health and stress resistance (a well colonised plant will be better able to cope with pathogen and pest attack and poor soil conditions)
7. Easy to use ( simply sprinkle into the bottom of the planting hole or mix with the gel solution provided )
