Guidance notes for using Rootgrow mycorrhizal fungi

Guidance notes for applying the dry granule formulation

It is very important that these granules come into direct contact with the plant roots. The planting process is,

  1. Dig planting hole as normal.
  2. Look at the base of the plant that is being planted and sprinkle into the bottom of the planting hole enough granules to cover ONLY that area.
  3. Place the plant in the hole directly on top of the granules (you shouldn't see many granules around the plant once it is placed in the hole.
  4. Backfill as normal with compost and whatever fertilisers are required.
  5. Mulch.

Words of caution

1.      Do not apply fertilisers directly onto the granules.

2.      Do not overdose, it will not benefit the plant and it is a waste of money.

3.  Rootgrow™ and Rootgrowplus™ do not help azaleas, brassicas, rhododendruns and heathers. Use Rootgrowplus™ for trees.

Guidance notes for applying the root dipping gel

  1. Take a large bucket and fill it up with the correct amount of water (see table below)

Quantity of water

450 Ml Tub

4 litres

5 Litre Tub

30  litres

10 Litre Tub

70 litres

  1. Add the sachet of white powder and stir well.
  2. When the liquid thickens add the granules and stir well. The granules should be suspended evenly through the thick liquid.
  3. Dip the roots of the plants in this gel and plant immediately.

Words of caution

  1. If you are dipping a bundle of whips cut the string holding them together and stir them to ensure that the centre of the bundle gets wetted by the liquid.
  2. If there is any gel left it will keep only for a few days in a sealed container in a fridge. Stir it well before using it.

Guidance notes for treating existing plants

It is possible to treat plants that are already planted out. Rootgrow is a living symbiotic

product and must have a living host plant to survive. Therefore you need to plant around

the plant to be treated (target plant) with other smaller plants that will act as a host. Below ground rootgrow will grow toward the target plant and infect it.

  1. Choose which plants you are going to plant around the target plant by consulting the table below.
  2. The number of plants you need will depend on the size of the plant that is to be treated.
  3. Generally plant up using an odd number of plants 3,5,7 or 9 spread equidistantly around the edge of the plant.
  4. The spread of the above ground parts of the plant will usually be mirrored by the roots so place the plants around the edge of the canopy.
  5. Plant them following the advice in the guidance notes for applying the dry granule formulation.
