More garlic

Carcassone Wight hardneck garlic. Next year’s crop

Well I did say that garlic growing had reached a whole new level of personal interest after the Allotment Association talk last Monday, and I wasn’t wrong.  The book I ordered – all 450 pages of it – was definitely a good buy, and coupled with some information from the talk I’ve been doing a bit of online research to see what the state of play is for organic gardeners..

The first thing to say is that the Isle of Wight Garlic Farm is not an organic operation and makes no claim to being one. I certainly don’t want to mount any high horse about that; it sounds like a commercial decision based on the challenges of achieving a consistent crop, and we’re free to buy or not to buy their products. Two things that were said induced me to get online.  In the QA session after the talk it was said that the farm uses Dithane to control fungal diseases like white rot.  They also operate a seven year field rotation, so they’re obviously taking no chances.  When he was asked what to do if you get white rot, the speaker said “buy another farm!” – I’ve got more on that later.

In fact they can’t use Dithane because it’s been banned in the EU, and they probably went over to Systhane until that was banned as well, and current regulations seem to say that there are no chemical fungicides available to gardeners for use on food plants. That’s not a worry for us because we wouldn’t have used them anyway, but we have to accept that our losses to disease will be much harder to reduce and will need a holistic approach to plant health coupled with some hard observation of soil, weather conditions and rotation.

The second thought provoking suggestion in the talk was to give the garlic a dose of sulphate of ammonia in February.  Sulphate of ammonia is a chemical fertilizer, produced by reacting ammonia with sulphuric acid. It adds, I discovered, both nitrate and sulphur to the ground but there are all the usual downsides of producing sappy, insect friendly growth and so-on. It also uses 1% of the world’s total energy production in its manufacture.  But alliums – onions, garlic etc – all need sulphur which is one of the molecular components of the garlic byproduct, allicin, which is so good for us. Normally there’s sufficient sulphur in the soil, but apparently – and here you must remember my knowledge of plant biology is limited – apparently waterlogging does severe damage to plant roots and restricts the uptake of essential minerals.  The take home point for us is that when we inherited our allotment the soil was continually waterlogged in the winter, and despite adding tons of compost; digging drains and raising beds, it’s still on the wet side.

The sequence of plant problems is that weakened plants get diseases more quickly and more severely than healthy ones. For the third consecutive year our leeks have been a miserable failure while others on higher allotments have not been affected. So putting aside sulphate of ammonia what else could be available to us as organic gardeners? One suggestion is to spray with a solution of Epsom salts – magnesium sulphate. It’s apparently allowable, but I’m assuming it’s a manufactured chemical and I know it hasn’t been made from natural Epsom spring water in living memory so it feels pretty non-organic to me. Then I came across some research on seaweed fertilizer which pretty much fits the bill.  We often use it as a foliar spray, but it wouldn’t have occurred to me to use it in February.  Research suggests that it’s a very effective source of minerals including sulphur. Anecdotally I can say that a car load of bagged and wet seaweed certainly smells as if it’s got some sulphur about it! – and it it makes a brilliant soil conditioner too. So in February we’ll spray the young alliums with liquid seaweed extract and I’ll report back. Other than that, I think we need to carry on raising the beds further above the water table and digging in organic material and horticultural grit.

Back to the book, and it’s been a revelation. I need to get a bit of organic chemistry into my head, but garlic’s claim to be a superfood seems to be well supported by independent research. The last 100 pages of the book are a summary of research into the use of garlic in folk and complementary medicine and  the use of alliums  and their derived substances as attractants, antibiotics, herbicides, pesticides and repellents in the environment. There’s all sorts of peer reviewed research in there including some work on companion planting which I’ve yet to read properly because I get excited and start skim-reading – a very bad habit and the reason why I’m not referencing any of the ideas.

But allotmenteering is all about taking the abstract and making it concrete, and so this all boils down to creating the best conditions for our own garlic by growing it in large pots filled with a home made mixture of soil, compost, horticultural sand, a sprinkle of fish blood and bone (not vegan then), and some vermiculite and perlite. This year we’re comparing 2 rows of Early Purple Wight softneck, grown direct in the allotment soil, and 25 plants of Carcassonne Wight hardneck in pots. They’ll all get the same seaweed treatment and hopefully we’ll be able to figure out how much the waterlogging is contributing to our difficulties. In practice this means carrying many kilos of ingredients down the steep paths and mixing them up in the wheelbarrow, which is extremely hard work but massively cheaper than buying bags of potting mix – which sometimes rely on peat in any case. This way we’ve only ourselves to blame if we get the mixture wrong.

So, after a hard day, we consoled ourselves with roasted root vegetables (mostly off the allotment) and couscous; another vegan tryout that was well worth the effort, but notwithstanding the affection of American readers for all things pumpkin – especially on Thanksgiving Weekend – even after being anointed with miso and all manner of herbs it didn’t really taste of very much.

The garlic book is –  “Garlic and other Alliums – the Lore and the Science” by Eric Block, Royal Society of Chemistry Press. 454 pages and I can’t put the price here because Madame occasionally reads this blog!

If only it were true!

Another walk along the canal today, and I was intrigued by the juxtaposition of the sign and a homeless person’s tent on the opposite side.  More often than not these temporary shelters are situated in places that are difficult for random thugs to reach because they are frequently targeted for abuse. This one tent is the tip of the iceberg and the canal is a favourite place.  There are probably dozens of rough sleepers along its edges – many of them with mental health and substance abuse issues, but it’s hard to tell.  Sleeping rough and living in fear of being beaten up or constantly moved on has its own corrosive effect. Then there are a large number of just-about floating narrow boats housing those who can afford the mooring fees but not much else.

Today the last half mile of the canal was rammed with boats unable to enter the river and head off towards Bristol.  The exit to the river through Bath Deep Lock is almost impossible in high water states because the long narrow boats have to enter the river broadside on, and the water was running like a train today.  Its deadliest state is always surprisingly quiet but always menacing.  Even Pulteney bridge gets quieter as the river rises and almost obliterates the weir in what looks more like a breaking wave. At this time of year when the Christmas parties get under way, the river has taken so many young lives it’s unusual to take a walk and not see a bunch of flowers tied to a fence.  Today was no exception. It’s cold at night, and the wet weather must have made life impossible for many homeless people.

Are we a humane society? We shall see in a couple of weeks, but I’m feeling despondent as our democracy is reduced to rubble by lies and deliberate lawbreaking.

My favourite little patch of weeds is coming along nicely at the moment, and there was a hint of sunny weather to come as the birds practised a few bars of their spring songs. As we wandered back into the town centre we discovered that the Christmas Market had started hours earlier than we expected, and so we hunted down the Isle of Wight Garlic Farm stall and bought some more seed garlic and a few other bits and bobs from Rob Solari who gave the talk at the Allotment Society AGM. When we arrived home the monograph on garlic that I’d ordered had already arrived so we’re well set up now.  In honour of the occasion we baked some large mushrooms with a wholly improper amount of our own crop and shop butter and thoroughly enjoyed them.

Up at the allotment the Early Purple garlic has finally emerged in sympathy with our new-found commitment and so the world looks like a better place just now. The kitchen waste had piled up in the kitchen and so we took it all up to the site.  The compost heap is going well, but a winter heap is an entirely different proposition to a summer one.  It’s dense with peelings and vegetable leftovers and therefore more attractive to rats and prone to going anaerobic, so it needs a lot more brown waste like cardboard and it needs turning regularly to let some air in. But it’s nice and warm – around 25C – and the worms are still reducing it at a tremendous rate. However much we put on the heap it seems to shrink day by day.

Everything else is quiet on the plots, but the broad beans and overwintering peas are germinated and ready to go into the ground over the weekend when the weather looks much better. But it’s just as well the pace has fallen a bit because the constant shortening of the day length and the grey wet weather seem to lower our energy levels. The table is piled high with books to read but it was better to be out walking for much of the day. We shift into official winter on Sunday which is promising brilliant sunshine and cold conditions – proper winter then, and the garlic loves a cold spell. The photo was taken in Sydney Gardens where we walked past a large Ginkgo biloba – this one without stinking fruit surrounding it.  Someone must have swept it all up.
