Rootgrow and rootgrowplus
It is very important that these granules come into direct contact with the plant roots. The planting process is,
- Dig planting hole as normal
- 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.
- Place the plant in the hole directly on top of the granules (you shouldn’t see any granules around the plant once it is placed in the hole.
- Backfill as normal with compost/soil and whatever fertilisers are required.
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 colonise it.
- Choose which plants you are going to plant around the target plant by consulting the table below.
- The number of plants you need will depend on the size of the plant that is to be treated.
- Generally plant up using an odd number of plants 3,5,7 or 9 spread equidistantly around the edge of the plant.
- 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
- Plant them following the advice in the guidance notes for applying the dry granule formulation.
