The ‘No Dig’ Diary – January 2018

Members may or may not have heard of this method of growing veg which has been espoused by Charles Dowding.
Clothall Road tenant, Annie, tells us more about it as we follow her on her ‘no dig’ journey.

‘I joined the library just before Christmas – I wanted learn more about pruning. What I found, was a book on compost. I like making compost. It’s very satisfying on so many levels. Perhaps that’s another diary thread for another time……but the compost book contained a chapter about no-dig gardening. How could that fail to catch the eye? That would be the best gardening revolution ever!
Several hours with Mr. Google followed, plus the chance arrival of an assortment of cardboard, and a few hours of free time over the Crimbo Limbo period. Fate decreed this was definitely worth a try.

Rather than try and convert the sceptics with technical persuasion (that can appear in later episodes), I shall just explain what I’ve done so far. Suffice it to say, ‘no-dig’ seems to mimic natural processes and therefore cannot be ‘wrong’.

One benefit of no-dig is to reduce weeding and the first step towards this is ‘sheet mulching’. I raked over a patch of ground (you can take out deep-rooted weeds if you like but this isn’t essential). Then I spread cardboard over the area. You can wet the cardboard but the ground right now is probably wet enough! Newspaper can be used instead of cardboard.

Then I covered the cardboard with a thick layer of compost (about 3 inches). I guess you could leave it at that, but in my garden the birds fling compost all over the place, so I covered the compost with whatever I could find – some bits of fleece, and old pea netting.

You could use black plastic but that would also keep the rain off. Aims of this mulching are twofold, firstly the mulch prevents light getting to weeds thus eventually killing them and secondly mulch gradually decomposes and is drawn down into the soil by worm activity.

Next time I shall explain ‘the path dilemma’ and hopefully tell what my solution will be.’

Allium Leaf Miner has Arrived!

Sadly, we have to report that allium leaf miner has reached deepest darkest Hertfordshire and has been spotted on both our sites here in Baldock. This pest first arrived in the UK back in 2002. It has come from mainland Europe and was confined for quite a time to southern and eastern counties but it has been gradually spreading since then.

And to make matters worse, allium leaf miner has two lifecycles each growing season and will attack all members of the allium family, particularly leeks and spring planted onions, shallots and garlic. There is no chemical protection available to allotment gardeners so the only thing that can be done is to cover crops with Enviromesh, and hope!

The adult flies appear in March or April, having overwintered in the soil. The females will feed on the leaves of your alliums before laying her eggs, usually near the base of the leaves of the plant. This can be spotted if you see lines of white dots on the leaves of your alliums.

The eggs hatch and the resulting larvae, which are tiny white, head and legless maggots, feed on the leaves before tunnelling (hence the name leaf miner) into the leaves. At this point, fully fed, the maggots pupate within the stem of the plant.

This second generation will hatch in September/October and again lay eggs at the base of the plant. It is this generation that will do the most damage to the now mature onion and leek plants. It will also overwinter in the soil ready to hatch the following spring.

It should be noted that most plants affected will tend to rot from a secondary infection from fungi or bacteria that develop in the damaged stems in the plant. The damage this fly can do is such that there can be no sign of your alliums being affected until the rotting is noticed.

So what can we do to protect our crops?
First off, employ a strict crop rotation policy. Do not grow alliums in the same area of your plot the following year.
Secondly, if your alliums do become infected, it is best to dig up the infected plants and burn them. As the pupae can survive over the winter, do not leave any infected plant debris on the soil.
Cover alliums with horticultural fleece, particularly when the flies are active in the spring and again in the autumn.
Plant out young plants after the danger of the first wave has passed and lift before the second generation is active. Whilst this may help with onions, leeks are in the ground for a long time so will not be ready for lifting in early autumn so covering them may be our only defence.

There is plenty more information online.

What to Grow on your Plot in September

September is the month when you start to see bare patches on your allotment as you harvest and dig up this season’s plants. But worry not, there’s still things you can plant out during the autumn months and first up is autumn onion sets.

Onion sets are immature onions which have been lifted and dried to stop any further growth. You can buy several varieties from the members’ shop now. We have Radar, Shakespeare and Blood Red available.

Plant them out now and water well and they will then resume growing over the winter months. Autumn sets are hardy so no need to worry about protecting them from frosts etc.

The sets can either be planted direct into the ground, just push them in root end first so just the tops are showing approx. 4″ – 6″ apart.

Or they can be started off in modules with compost and planted out once the top growth is a few inches high.

Either way, I like to protect mine from being pulled up by pigeons until they have established themselves by covering them with a mesh tunnel.

Autumn planted sets are usually ready for harvesting a short time before spring planted sets, so I find it’s a good way of spreading the harvesting season. Once harvested, onions store well. Just string them up and hang in a shed or bin store in my case.

Starting from Scratch – Onwards and Upwards!

So, it’s been a few months since we last caught up with Yvonne and Steve on their new plot. When we last met them, they had just acquired a shed on FreeCycle.

The shed was a 8ft x 6ft shed which Steve chopped down to make it 3ft x 4ft with a veranda! Steve and Yvonne assembled the shed in their garden before transporting it to their plot on a roof rack.

New felt on the roof and a lick of paint and it was good to go!

A recent addition has been a decking area at the front made from a free pallet.

In the meantime, their plot has continued to fill up with crops.

And they have enjoyed a good harvest

And now as autumn approaches, it all starts again with clearing ground and planting autumn onion sets and garlic.
Yvonne and Steve have done amazingly well in such a short space of time on their plot. Long may it continue!

Starting from Scratch – A Year in the Life of a New Plot

In this series of articles we follow Yvonne and Steve during their first year as allotmenteers showing you what can be achieved with a bit of effort and hard graft.

New tenants, Yvonne and Steve took on their plot in mid April 2017. They had no previous allotment experience other than going to their father’s allotment with him when little. They chose a half plot on the Clothall Road site. The plot hadn’t been worked for many years, although a recent tenant had dug out outlines of beds.

The plot had been strimmed in readiness for letting by site rep, Martin Luker, but some weeds still remained.

Keen to get started, they made good progress very quickly and had dug over several beds within a couple of weeks.

A quick visit to the members’ shop and they were able to plant seed potatoes and onion sets and start some seeds off at home.

A week or so later and more beds were dug and a base laid for the shed, both of which were picked up for free after searching online.

Within a month, amazingly they had dug over the whole plot.

And were excited to see the first signs of growth as their seed potatoes made an appearance.

Yvonne and Steve have worked really hard over the month to get the initial digging completed. They have also followed sage advice and planted a little too so they can see signs of growth; a reward for all their hard work.

In the next instalment we’ll see what plans Steve has for the shed!

Potato blight

I used to think that potato blight was only of relevance to a study of Irish History. This is very far from the truth, it was a problem throughout Europe, parts of Germany were badly hit as was the Isle of Man and parts of Northern England. But above all the virus is still active to this day.
There is more than one form of blight. The one that seems to be a regular visitor to Baldock allotments is not the one that caused the potato famines, it is “Late Potato Blight” that also attacks tomatoes. The “Late” is a confusion it may well have been Late where it was named, but it’s not late in Baldock.
This is the scenario: you are congratulating yourself on the perfect potato crop, then one day you breeze into the allotment, the first reaction is “what low life let his rhinoceros roll in my potato patch”. The tops have collapsed, the leaves are shrivelling. If you don’t intervene now the blight will find it’s way into the tubers and they will rot and you will have lost the crop. The remedy is to remove the diseased foliage as soon as possible and burn it, don’t put it on the compost. Tomatoes fare even worse than potatoes the lost yield can be of the order of 60%..
There was a move in 2015 by the commercial potato growers to get a ban on amateurs growing the crop. The measure didn’t get very far, not a great vote winner, but it does illustrate the seriousness of the issue.
Bordeaux mixture is recommended as a preventative, it is available from the shop. We have a small stock. It has now been banned. There are substitutes available but are they as effective who knows?
Such were the problems last year both on the Clothall Common and North Road sites that the General Committee have added blight resistant varieties to the range offered.
