Contains Rootgrow™, the first and currently the only plant or soil treatment licensed by the Royal Horticultural Society.

Keep evergreens lush and strong with this specially formulated organic fertiliser that feeds both plant and soil.

Containing alfalfa and nitrogen fixing bacteria, this is an abundant source of plant-available nitrogen, guarding plants against browning and leaf drop.

Seaweed meal and Rootgrow mycorrhizal fungi are included to stimulate root growth and improve nutrient and water uptake, and beneficial microbes added to enrich the soil for a long-term improvement in growing conditions.

Great for all evergreens, including containerised topiary, rhododendrons, azaleas, conifers, bay trees and buxus.

How does Rootgrow work?

Rootgrow mycorrhizal fungi bond to a plant’s roots, effectively becoming part of its root system. They grow rapidly in search of water and nutrients, and as they're finer than the plant's coarse roots, they’re better at reaching them - helping plants thrive in even difficult soils.

In poor sandy soil, they track down scarce nutrients and water, and in dense clay soil they unlock nutrients, acting like a clay breaker. They're great at hunting down phosphorus and potassium for flowering and fruiting, but also thrive on finding trace elements. And they hold onto water like a sponge, giving your plants far better drought tolerance.

How to use

Gently work a few handfuls into the soil at the first signs of growth in spring. A further feed later in the season can be used to combat leaf drop and discolouration if needed.

If planting, we'd advise using pure Rootgrow, placed in direct contact with your plant's roots, and only applying After Plant as a follow-on treatment.
