The Derbyshire-based company will spend the money on developing its national network of agents, supporting nursery trials, product development and marketing support for retailers. Also planned is an expansion of the firm's regional production facilities.
More than £8m was spent developing the in-vessel composting plant at Ashbourne. Managing director Steve Harper said Vital Earth could "tick all the environmental boxes" with regard to consumer demand for products that boasted a reduced carbon footprint or were organic and chemical-free.
"Vital Earth is bringing a seriously green proposition to the garden care consumer at just the right time for retailers to benefit. This investment demonstrates the commitment we have to this market and to the green ideals we represent."
The company's products are recycled and sourced from the UK.
