Across the site we have a wealth of knowledge and experience. We will be posting advice here collated from our plot holders and the wider allotment and gardening community for the benefit of everyone.

December Hints & Tips

December is the time of year where we are all thinking about the festive season, meeting family and friends and having a jolly good time and we now hibernate into our cosy rooms and forget about our plots until the weather warms up.

Well surprisingly December is not necessarily a month where allotmenteers can stand idle as you might think. With luck the brassicas should be at their peak and you will be picking Brussel sprouts cabbages cauliflower and the indestructible kale. Fresh root vegetable, will also be available for those hearty soups and roast dinners. A few salad delights such as endive, winter purslane, corn and even perhaps Lettuce and rocket will be ready to harvest if you have grown them in a cold frame of greenhouse or even under cloches.

Lifting and storing root vegetables need space which some may not have, so making, soups and blanching for the freezer may be an option or indeed pickling. Celeriac and parsnips can stay in the ground if there’s no risk of their being “frosted in”. Straw will help protect them.

Now is the time to check wires and ties, staking of plants, clean tools, pots and seed trays. Give the pots and trays a thorough clean. This will prevent any diseases or viruses carrying over and infecting the new seedlings next year.

Remove dying leaves from your brassicas and check for slugs and snails in-between the outer leaves.

You will know that rats and mice as winter approaches are a problem on site, they tend to nest in compost heaps and dig up broad bean seeds, garlic, shallots and onion sets, planted in the soil for early cropping. Turning over your compost may well help stop the nesting of these animals.

In my last Hints and tips, I said November was the month to plant out garlic and rhubarb, bare root trees and prune trees and outdoor vines. Inspect the trees for canker and cut out the diseased wood as well as any damaged branches. Renew grease bands on the fruit tree trunks if necessary.

However, it’s not too late to dig your plot in December although digging on our allotment this time of year will be hard going as it tends to get waterlogged so perhaps it’s now best to leave it until March next year. But what you could do to make it easier for yourselves is to mulch the area you wish to cultivate or cover these area with black plastic until you have the energy to dig. Remember our plots have to have three quarters of the ground cultivated in order to meet with the rules and regulations.

Of course, digging is an option and there is another way to make sure the condition of your soils in your cultivated areas are ready for sowing and planting.

Talking about digging gives me the opportunity to talk about soil which I think is quite fascinating and I hope you will too after having read the following article.

Anyway its time to move on and in closing I would like to wish you all a good festive season and to meeting you all on site next year.

Soil Management

George Monbiot, the Guardian’s environmentalist journalist has written extensively about soil and reveals how our changing understanding of the world beneath our feet could allow us to grow more food with less farming./ effort. In his book Regenesis he goes into great detail into the structure of our soil, the diversity, interconnectedness and the abundance of critters living in the soil. These creatures range from springtails- 100,000 beneath a square metre of ground, microarthropods, Oribatids- sub group of mites which are a sub group of Arachnids – spiders, caramel beetle larvae, clusters of translucent globes containing faint white crescents of snail embryos and Nematodes - flat worms producing 400000 offspring a year and indeed many more critters too numerous to mention. In addition to these creatures are the well-known larger woodlouse, millipedes’ snails, earthworms-that produce natural drainage to the soil, and slugs we love to hate in various quantities, all occupying the same niches on our plots. These creatures interacting together and help the production of our soil but more, as science and research reveals is not the only story in town. Fungi whose fruits we see through mushrooms and toadstools also form a relationship with plants, Millions of fungi species live within the soil many lacesthrough and proliferate between plant roots on which they depend. Most plants rely on these fungi to gather minerals and moisture from the soil. The pants feed the fungi and in return the fungi feed the plan twith nitrogen, phosphorus and other elements. This symbiotic relationship is at least 460 million years old.

Further research of soil and how plants interact with each other show that plants “talk” to each other using these fungal filament interconnections. These talking patterns relate to the lack and transfer of nutrients from one plant to another and the signalling of attack from pests or disease. In fact, it has been shown that plants use their bacteria to prime their immune systems and send signals to underground predators to attack the unwanted bacteria.

So, you say why am I painting a picture of the soil underfoot and on our plots? Because, as we understand more about our soil we begin to understand that each time we dig we destroy in part the structure and biodiversity inherent in the soil.

So, is there another way we can overcome this dichotomy, the desire to dig and remove weeds in order to prepare the ground for sowing or leaving it to enhance the soils’ biodiversity and structure?

George Monbiot recites a story of a friend of his, Ian Tolhurst who has been a farmer for thirty-three years, farming a seven hectare previously low productive site riddled with rubble. Over these thirty-three years he has farmed his land without pesticides, mineral supplements, animal manure or any type of fertilizer. He has pioneered a way of growing vegetables and fruit that he calls stock free organic. This means he uses no livestock or livestock products at any point in the farming cycle. While adding none of these soil improvement methods he has raised yields until they have hit the lower bound of what intensive farmers achieve using artificial fertilizers on good land.

So how did he do it, Tolhurts describes his land as a Biodiversity and this biodiversity drives the farm. In fact, he says vegetable are a by-product of that biodiversity. He supports this biodiversity in a number of ways which include the abundance of predators because that biodiversity attracts a wider range of pests. So, for example aphids love nettles, in turn these keep ladybirds alive and as soon as he needs them for crops, they the ladybirds move onto crops, ground beetles eat slug eggs and baby slugs, frogs each slug and snails, worms make natural water ways in the soil for drainage and aeration.

Tolhurst tells us that we don’t need a huge lot of nutrients either, just at the right place at the right time. And for that to happen you need the right soil biology. He explains the biggest loss of nutrients is through leakage, water moving sideways and downward so if one leaves it bare it wont grow anything. One has to make it “water tight” that means using plants to hold onto nutrients and to do this he uses “green manure” over the winter period or he keeps the soil covered. In our case of course it would be, green manure, black plastic or a preparatory weed covering, but not carpet as it’s against the Association rules! However, Tolhirst sees the “green manure” as a key to his whole system. It bunds nutrients, fixes nitrogen, adds carbon and enhances biodiversity to the soil. Obviously to enhance the soil with the carbon rich green manure the soil needs to be turned but in Tolhurst case its only once every three years. In addition to the green manure Tolhurst uses partly broken-down woodchip, as a mulch. When it’s still chip but dark he spreads it over the green manure twice every seven years and leaves approximately seven millimetres of chip for the worms to take it down into the earth. The area is then ready for planting.

Wood chip mulching


His records of soil fertility have shown that soon after he started adding chip to the soil, fertility of his soil soared and in five years his yields had roughly doubled.

So, if you don’t dig why not try this methodology and see if you can double your yield like good old Tolhurst?

I started this methodology, without “green manure” last year on one bed and I had a good crop of French beans. I did no digging and only took out the weeds as they showed themselves. A second bed was given a good dose of woodchip at the beginning of this year and the soil now appears up for planting as most of the woodchip has been taken down by the critters. I have pulled up the remaining vegetables on a number of other beds and applied woodchip to them in November so I will be keen to see how these beds will perform.

November Hints & Tips

November is the month to ensure you’ve got a sharp pair of secateurs – it is the time for pruning fruit trees and bushes before the weather turns very cold. The exception to this is stoned fruit trees such as cherry and plums, which are pruned in mid-summer.

It’s also the best time of the year to plant new, bear root fruit bushes and trees. The soil will still be warm, and if you prepare the planting holes by adding a generous helping of compost or manure, the roots will be able to establish themselves before winter really sets in. If you miss this month, you may have to wait until next March.

Before the soil becomes too cold or waterlogged, November is also a good time to prepare the ground for next year’s growing season. Clear away old plants, remove any surviving weeds, turn over the soil and dig in your soil improver - be it well rotted manure or compost. Or if you are following ‘no dig’ practices, add 1-2 inches of compost or manure to the surface of your beds and let the worms do the rest.

Once the ground has been prepared you can either leave beds to be exposed to frosts, which can help kill pests and breakdown clay soils, or you cover up with black polythene, cardboard or a proprietary weed suppressant. You are not allowed to cover the ground with carpet in order to suppress the weeds at any time of the year.

You may know the rules in respect to cultivation but just to remind those that have just joined us here’s what the Bye-law 3.1 says:

“The Tenant’s plot requires a minimum of two thirds in active cultivation and fertility…. A greenhouse or poly tunnel is included in the two-thirds calculation. Lawns are not considered to be part of the two-thirds cultivation”

At this time of year, plot cultivation is about maintenance and soil improvement.

Nets can be removed from fruit cages but keep them over Brussels sprout, cabbages and other brassicas.
