Beyond Organics: Holistic Orchard Management

We recently taught one of our permaculture design courses at Ragmans Farm in the Forest of Dean. For years they’ve been innovating with permacultural ideas and their latest trend is holistic orchard management.

Ragmans Farm

One key to the system is the use of aerated compost tea. This is a preparation of beneficial microbes, made by bubbling air through water to which a small amount of good compost has been added. There are various other optional things you can add to feed the microbes and Peter Kafno, who works on the farm, took us through how he makes compost tea step by step.

Peter Kafno explains the craft of making compost tea.

For complete instructions on compost tea he recommends the book Teaming with Microbes. An important detail, which was new to me and doesn’t occur in the book, is that these days you can’t use mains water. It used to be possible to get rid of the chlorine by leaving it to outgas over 12 hours. But now water companies are using chloramines, which are more stable than chlorine and will not outgas. They will kill the microbes – which is what they’re designed to do, after all – so now you have to use rainwater or spring water.
If you have a small garden and are able to make enough compost to dress the whole garden with it every year or two it’s probably not worth making compost tea. But on larger areas, where that amount of compost would be out of the question, it really comes into its own, bringing the biological benefits of compost without the need for masses of material. At Ragmans they spray the orchards around once a month through the growing season.
‘We do still get diseases in the orchard,’ said Pete, ‘But it’s a balance of diseases, with none becoming dominant and posing a real problem.’
Matt Dunwell, the farmer, then showed us round the orchards and explained the whole system. Much of it is based on the work of Michael Phillips, the pioneering American orchardist, and Matt recomends his book. Most organic fruit growers spray every 10-20 days with copper fungicdes to control fungus diseases and keep the fruit unblemished so it looks good on the supermarket shelf. ‘That is suppressing disease,’ he said. ‘By contrast, what we do is probiotic, encouraging life.’

Matt tells us about hoistic orchard management.

As well as using the compost tea, they mulch the trees with ramial woodchip. This is woodchip made from small branches and it’s higher in nitrogen and other nutrients than woodchip made from larger wood. It has the effect of encouraging a fungal microflora in the soil, which is beneficial for tree crops, as opposed to a bacterial one, which is what’s wanted for annuals such as vegetables and cereals.

One problem is that the fruit is not as visually perfect as fruit sprayed with copper fungicides. There are two solutions to this. One is to educate your customers. Imperfect fruit goes well in a box scheme, where there’s more direct contact between producer and consumer than there is through a shop. The vegetable box scheme at Ragmans is just starting up again now, after a few years in abeyance, and fruit sales will be integrated with it. The other way is to make juice and this is just what they do. In fact the orchard was originally planted to supply their existing apple juice business.
‘What we’re doing is very much an experiment,’ he said. ‘We’re moving away from industrialised agriculture but real ecological agriculture is probably a hundred years away. There’s no-one doing it now. I call what we’re doing “modern agriculture”.’

Munch, munch!


  1. thanks for such a perceptive blog Patrick – its great to have our work interpreted and posted by you. We had John Edgeley look around the orchard last week. He used to lecture at Pershore and you probably know him as an orchard expert.

    He was very complimentary about our trees, and the management plan we have. He is into compost teas as well. It gave us a lot of confidence to have someone of his calibre giving us the thumbs up!
