peat free compost from Petersfield Growing Mediums (UK)

Petersfield continue to be at the forefront of peat free and reduced peat compost development, we first manufactured peat free mixes in 1991, mainly for the local authority market.

By 1994 we had developed Peat Free Supreme, a soil, bark, coir mix that out performed peat composts in several ways, this was proven by independent trials in 1995.

We supply peat free composts to an enviable client base that includes The Royal Households, The National Trust, English Heritage, The Royal Horticultural Society, The Zoological Society of London and Cambridge University Botanical Gardens.

Continuous research and development means that we now manufacture Peat Free composts and growing mediums from possibly the widest range of raw materials in the industry, both for commercial growers and retailers. We have compost mixes and recommendations for almost all crops.

Prescription mixing:
All Petersfield's mixes can be tailored to suit individual grower or plant requirements. We can advise on mixes to suit a wide range of specific crops and applications.

Product development:
At Petersfield we are continuously working to improve our products and have ongoing trials with new blends. Peat alternatives are developing particularly quickly, please keep in touch for the latest information.

Reduced Peat Composts:
We have many recommendations for situations where the grower does not want or need to go fully peat free. Many reduced peat recipes offer improvements over 100% peat products.

It still remains difficult to grow ericaeous plants in 100% peat free mediums, consequently we have developed a 50% peat mix which is producing excellent quality and reliable results for professional growers.
