What is Rootgrow?

Rootgrow is made from naturally occurring, symbiotic fungi. It is applied as a powder or gel directly to the roots when planting your bareroot trees and hedging in particular, but is beneficial for pretty much all plants (there is a separate product for ericaceous - acidic - soils, which we currently don't stock).

The main ingredient is mycorrhizal fungi, organisms that co-exist naturally and beneficially with the roots of most plants and trees, both protecting and nourishing them.

How does Rootgrow work?

Mycorrhizal fungi dramatically increase the ability of roots to absorb essential nutrients from the soil and form a little buffer against disease and dry soil. In return, the growing roots provide the perfect environment for the fungi to thrive. It's a natural, symbiotic relationship that greatly improves the growth and survival of your plants, whilst improving the quality of your soil and, in poor soils, its water retention.

Once established, the fungi will continue to grow in harmony with your trees, bushes and plants, providing a lifetime's supply of natural nutrition.

It really helps to reduce the 'transplant shock' of moving plants from relatively sterile pots to natural earth. The formula carries an inert clay substrate and a number of bio-active ingredients to give your plants the best chance to settle in smoothly.

The shelf life is one year in a cool dry place, and that is surely conservative, but we recommend buying the correct amount and using it promptly if possible for the best results. 

Which Rootgrow size do I need?

Rootgrow comes in 150 gram, 360 gram or 1 Litre resealable pouches, and 2.5 or 5 litre plastic tubs. Except for the 150g pouch, all sizes of Rootgrow come with a gel additive specially for use when planting bareroot hedging.

  • Use Rootgrow in powder form for potted plants, bareroot fruit trees or ornamental standards.
  • Rootgrow gel works better if you are planting bareroot hedging, roses or soft fruit.

When you have placed all of your items in your basket, we will automatically calculate how much Rootgrow you will need, and you will have the opportunity to add this to your order before checkout.

Please note that these figures are approximate and can vary considerably depending on root formation and plant type.
