RootGrowKey Benefits of Planting with RootGrow

RootGrow enhances a plant's root system so a newly planted plant:

  • Finds more food, finds more water.
  • Needs less fertilizers.
  • Establishes quicker and reduces failure rates.
  • Has increased tolerance to drought and adverse soil conditions.

These "friendly" mycorrhizal fungi are completely natural and organic and native to UK soils.

How to use RootGrow

The mycorrhizal fungi granules need to come into direct contact with the plant's roots.

There are two methods of application, as a dry granule for container grown plants and as a root dip for bare root plants.

Pot/Container Grown Plants

A good rule of thumb is to look at the bottom of the pot to be treated as you will need enough rootgrow granules to lightly cover this area. To do this, dig a hole to the correct depth then lightly sprinkle the bottom of the planting hole with rootgrow and plant the plant directly onto the granules.

For very small plants from the cell grown range (marked Cg in the catalogue) again the principle of getting the granules into contact with the roots is important. Water the plants and then roll the root plug onto a saucer of granules and whatever sticks should be enough.

For seed trays mix rootgrow 1:19 with the compost. As a guide this table shows how many plants the different packs of RootGrow will treat.

Bare-Rooted Plants

To treat bare root plants (Shown as Br, Tr or Sd in the catalogue) the most economical and effective way is to make up RootGrow as a dipping gel. You can use the non-gel mix on bare-rooted plants by sprinkling it on the roots.

For plants with very large roots it may only be necessary to dip the lower half of the roots. For plants with very small roots it is advisable to dip the whole root.

The amount of RootGrow you need depends on the root size. As a guide this table shows how many plants the different packs of RootGrow will treat.

1. A source of organic matter and soil conditioners to improve the soil.
2. A source of nutrients from the most sustainable and organic sources possible.
3. A kick start for soil biology with bacteria, fungi and stimulants to make the plants grow.

How Rootrow Works

The white roots are produced by Mycorrhizal FungiMycorrhizal Fungi are widespread throughout nature and are a fundamental reason for normal plant growth and development. In fact 90% of all plants rely on a Mycorrhizal Fungi root system.

Such fungi colonise plant or tree roots, extending the root system into the surrounding soil, via an extensive network of fungal filaments (up to 20 metres in a teaspoon of soil). These thread-like filaments extract nutrients and water from a large soil volume and exchange them for carbon from the plant. This secondary root system, when established, links the root systems of adjacent plants or trees and helps share, more efficiently, nutrient resources throughout the plant community.

All the white roots on the Larch seedlings in picture are 'Friendly Fungi' roots, the thicker red/brown roots are the Larch's roots. This fungal network increases the volume of soil explored by the plant by up to 700 times.

Gardening including hoeing, tilling and regular chemical fertilizer use can inadvertently disturb and reduce the friendly fungal root network. Equally, the roots of some plants may seek a fungal partner that is not abundantly found in our gardens. Without changing your garden methods you can introduce mycorrhizas suitable for UK gardens through a simple application of RootGrow to the planting hole during planting out.

It is now recognised that the lack of the mycorrhizal relationship is a major cause of poor plant and tree establishment. While a plant will gradually develop its own mycorrhizal root system, planting them with RootGrow will speed this process up. It can take up to 3 years for it to develop naturally, while using RootGrow can get the mycorrhizal root system established within one month.

RootGrow Gel Mix is ideal for treating bare rooted plants and large quantities of pot grown plants. If mixed up in a bucket plants can be dipped in this before planting.
