Rootgrow gel is designed to treat bare rooted plants such as hedging, fruit canes, roses and trees. Rootgrow 'friendly' mycorrhizal fungi are all-UK origin species of fungi that are proven to benefit plants under UK soil conditions and climate. This is the first and currently the only plant or soil treatment to be licensed by the RHS. Mycorrhizal (or 'friendly') fungi play an important role in developing healthy, strong plants. The fungi occur naturally in soil, effectively creating a secondary root system which grows out into the soil searchin. Ideal for bare root plants, it contains a gel powder sachet to mix with water and the rootgrow for dipping.
