RHS Rootgrow Mycorrhizal Fungi

RHS Rootgrow Mycorrhizal Fungi

Rootgrow™ contains beneficial mycorrhizal fungi that form a natural, symbiotic relationship with plant roots.

Once established, the fungi extend the effective root system - dramatically increasing the plant’s ability to absorb water and nutrients.

This extended root system provides lifelong support to the plant - rather than just the short-term boost you'd expect from common fertilisers.

The resulting enhanced water and nutrient uptake leads to better flowering and heavier cropping in ornamental and edible plants.

Where plants have previously struggled to establish themselves in your soil, Rootgrow™ can be highly beneficial.

Suitable for use on trees, shrubs, roses, edibles, bedding plants and flowering ornamentals. Not suitable for use with ericaceous plants (e.g. rhododendrons, azaleas, heathers, blueberries). For these, an ericoid mycorrhizal product should be used.

This product is endorsed and produced under licence from the RHS.

Available in 60g, 150g and 360g packs to suit both small garden projects and larger planting schemes.

Scoop included for easy and accurate dosing.

Directions for use

Apply only when planting out new plants. The manufacturer advises that Rootgrow™ must come into direct contact with the roots to be effective:

1. Dig your planting hole as normal.
2. Sprinkle Rootgrow™ evenly into the base of the hole. Use the guidelines for application rates below.
3. Ensure roots come into direct contact with the granules.
4. Position the plant, backfill with soil and water well.

1 scoop ≈ 10ml. Roughly follow these amounts depending on your pot size:

- 2L - 2 scoops (20ml)
- 5L - 4 scoops (40ml)
- 10L / 15L- 7 scoops (70ml)
- 25L - 12 scoops (120ml)
- 50L - 16 scoops (160ml)
- 100L - 32 scoops (320ml)

For seeds and bulbs, sprinkle Rootgrow™ into the planting hole or trench.

Rootgrow™ can be used alongside slow-release fertilisers.

Once established, the fungi should persist for the life of the plant.
