Based on nature. Rooted in science. 5 years in development. Over 100 in-house and independent trials. Root health is quite literally the foundation of plant health. Rootzone is an organic-based biostimulant that boosts growth, supporting a bigger, stronger, healthier root zone which benefits the entire plant.

Suitable for all plants.

What's in the bottle:

Rootzone is an organic-based biostimulant that nourishes plants from the roots up.

• A balanced blend of marine extracts, fulvic acid, amino acids, thiamine, and potassium.

• Stimulates the natural root growth process, enhances nutrient uptake, and increases resistance to pests and diseases like root rot.

Marine extracts:

Rootzone includes the natural growth booster, marine extract Ascophyllum Nodosum. An organic biostimulant rich in natural growth hormones, including cytokinins, gibberellins, and auxins, involved in every stage of plant growth from foliage to flowers, but especially in the growth of new roots.

Amino acids:

Rootzone includes amino acids, organic plant proteins involved in multiple plant growth processes.

• Aid in the production of chlorophyll, boosting photosynthesis, growth, and soil health.

• Help plants grow bigger, stronger, and denser.

• Support better use of nutrients from the soil, improving soil fertility and reducing unused fertiliser salt build-up and burn.

Fulvic acids:

Tiny, golden, soil superheroes! Fulvic acids are a type of organic electrolyte, formed during the breakdown of organic matter in soil.

• Naturally occurring and golden in colour, fulvic acids help transfer life-giving nutrients from the substrate to the roots.

• Reduce the risk of nutrient lockout and fertiliser build-up, improving absorption and use of nutrients vital to plant health.

• Boost growth of roots and shoots, while helping protect from common abiotic and biotic stresses, like root rot and fertiliser burn.

• Loosen compacted soils, increasing aeration and drainage, reducing the risk of root rot.

Thiamine (B1):

Thiamine (Vitamin B1) is most abundant in shoots, roots, and seeds. Part of what we think of as a plant’s immune system.

• Boosts a plant’s natural defence system, increasing resistance to pest attack and pathogens like root rot.

• Aids recovery from root damage and reduces transplant stress after repotting.

How to apply:

Growth Technology Rootzone can be mixed with your fertiliser. It is also designed to work alongside CCS to strengthen new roots on propagations and cuttings.

• Gentle yet super-concentrated. 250ml makes up to 500 litres.

• For cuttings and seedlings (in combination with CCS): 0.5ml per litre of water (1ml per 2 litres water).

• For established plants (in combination with any GT Fertiliser): 1ml per 1 litre water.

How often to apply:

• Best used throughout the plant lifecycle, every time you water.

• For best results, use with your usual fertiliser.

• Rootzone is formulated to be used with GT CCS for cuttings and seedlings or with your best-match GT Focus fertiliser for established plants.

Available sizes:

250ml and 1L
