The latest edition of Which? Gardening magazine has compared various brands of compost for effectiveness and value for money. Their horticultural experts planted hundreds of flowers and vegetables in 21 different brands of compost – and guess what? Peat-free came top of the pots yet again.New Horizon Peat Free compost wins for the second consecutive year. This goes to show that peat-free can produce the kind of results gardeners demand. Kew Gardens already know this because they don’t use peat. Ditto, the National Trust, Monty Don, Charlie Dimmock and a host of others. Geoff Hamilton, the unofficial patron saint or all amateur garden potterers, was a great champion of peat-free gardening.Case closed, you’d think. But to quote from an RSPB report which went to ministers earlier this week,“The voluntary approach to resolving the problem has failed. Indeed, in recent years the transition towards alternatives has virtually stalled and peat use in the UK fell only 1.63% (around 50,000 m3) between 2007 and 2009. At this rate of decline, the horticulture industry will not be peat free for another 120 years.”So if there are decent alternatives available that don’t cost any more (10p a litre for New Horizon is about average for compost these days), why the snail’s pace progress in moving from the environmentally destructive, unsustainable, greenhouse gas emitting peat based brands to the harmless peat free alternatives?Well, let’s look a little closer. The brand which fared worst in the Which? Gardening survey was also peat-free (Miracle-Gro Organic Choice, you have been named and shamed) and several other peat-free brands produced poor results.And after a quick perusal of a few popular gardening forums it seems that although most decent gardeners know there is good peat-free stuff out there, they can’t buy it down their local garden centre.The Which? article comments: “It’s odd that some manufacturers seem to be further encouraging the use of peat. We have noticed three of the big compost producers are bringing out new peat-based products this year. The launch of these products comes at a time when the peat-free market has never looked so rosy. Sales of New Horizon (a Best Buy compost for containers in this year’s trial), shot up by 35 per cent between August 2009 and July 2010.”On this evidence neither peat producers nor retailers seem to be fully behind the push to phase out peat. The retailers aren’t producing enough high standard peat-free products whilst at the same time bringing out new peat based products, and the garden centres aren’t stocking bags of the proven decent stuff.Why? I’m sure they will cite ‘market forces’ and ‘commercial reasons’, but then they are businesses and can hardly be blamed for trying to make money. So why doesn’t the Government, which can’t hide behind such excuses, subtly change those market forces by introducing a levy on peat-based products, as we suggested in our report this week?If peat-free is cheaper, people will buy more of it and the industry will invest in production and distribution. It’s a no brainer really. The budget is on March 23, watch this space...

You have made yet another mistake because the Glendoick website is citing the example from where your erroneous statement arose. You say sphagnum growth is really slow at 10mm per year and this is a very generalised statement and in many cases is wrong. Sphagnum girgensonii and sphagnum fimbriatum grow in wet birch and pine woodlands and can produce aprox 15cm of growth in a good wet year. I know this from experience of gathering sphagnum moss (with permission ) for hanging baskets. The moss was gathered from the same small area each year and each year it had regenerated by a vast amount!
You have such a blinkered aproach to this peat debate that you are missing out on the true way forward which is sustainable harvesting of peat. This is perfectly possible. Lastly raised peat bogs in the UK are SSSIs if they have any nature conservation value and are already protected. Some large areas of raised mire also belong to English Nature.
Please comment on the cultivation of peat soils in the fens and state what the rspb is doing to stop this destruction of peat resources which are dissappearing rapidly due to farming practices increasing decomposition.
