Keeping pests at bay

Garlic (Solent Wight) on the left, Egyptian walking onions behind, hopefully protecting the Chinese broccoli (kailans) and kohl rabi seedlings. The copper-lined collars prevent slugs and snails from reaching the brassica seedlings.

I planted out these heavily guarded brassica seedlings yesterday. Bitter experience has taught me that they need this level of protection. The copper-lined collars are made from sections of 500ml plastic water bottles trimmed with copper tape around the top and will deter slugs and snails. The metal reacts with the mollusc's mucus when it tries to cross the copper strip and gives it a shock-like sensation.


I've found these home-made copper rings perfectly effective and use them with brassica seedlings, cucurbit seedlings, lettuces, of course, and also globe artichokes when they are first planted out. I can still remember the heartbreak of coming home after an Easter weekend away and finding my globe artichokes, planted out on Maundy Thursday, had vanished. The only clues to their disappearance were a number of long, ribbon-like, shiny trails.


The only drawback really, apart from the need to have as many collars as you have seedlings in the ground at any one time, is that the slug/snail population isn't controlled. In a particularly sluggy year, they will go off to try to find something else to eat that's unprotected. One year I found slugs attacking the beetroot, which is not normally vulnerable. This year, with a wet April with showers interspersed with sunshine, we are on Code Red as far as slugs and snails are concerned.


The second level of protection here is the perimeter planting of various alliums. I have deliberately positioned garlic (pictured here is Solent Wight, with elephant garlic out of shot) and onions around the outside of the raised bed to deter cabbage whitefly. Alliums are often planted with carrots to deter carrot fly, as it is said that the onion smell confuses the carrot fly (and also that the reverse holds true, the carrot smell deters the onion fly who is after an allium snack). 


Here I am hoping that the same principle holds true against whitefly. If this mini-trial proves successful, and the kohl rabi and kailans in the raised bed remain relatively whitefly-free, I will extend it to the main brassica bed, where the cauliflower, broccoli and cavolo nero will be planted later in the summer. Last year, the cavolo nero in particular was horribly infested with whitefly to the point of not being able to harvest it.


Copper tape is available from larger garden centres and from a number of online gardening suppliers. It's well worth searching and shopping around as prices can vary widely. Copper rings are also available but tend to be much more expensive while performing exactly the same function as the homemade rings here. For a copper ring with a larger diameter cut sections from a 2l water bottle.

Clockwise from top left: cut an empty water bottle into sections; take the mid-section and line with copper tape, tucking the ends over the rim to make a neat edge.

Hungry gap suppers

We have nearly run out of food at the allotment – and a good thing too. The last of the winter veg have more or less been eaten up and we need the space for this year’s crops. In the case of the leeks, the last four or five left standing are pretty spindly and look more like spring onions. With the purple sprouting broccoli maturing nicely and first pink asparagus bud just breaking the surface, I want to look forward to fresh and dainty spring meals, not hark back to winter sustenance.

With a view to finishing off the last of the crop, I picked as many viable cavolo nero leaves as possible and the last January King, so that I can now dig out the winter brassicas with a clear conscience. Back in the kitchen, I dug out the jar of dried borlotti beans to find only around 200g left. Now, these will store perfectly well until this year’s borlotti beans are picked, but they do go so well with the cavolo nero I couldn’t resist, and put the whole lot in to soak.

The beans were cooked very simply then dressed with a little olive oil. The cavolo nero was washed and simmered briefly, then mixed with a little sautéed garlic and the beans stirred in. The beans are beautifully plump – is that because they are still comparatively fresh? - and  have the best texture of all dried beans, really quite dense and mealy. The cavolo nero in contrast is dark and silky. I ate this topped with a fat and juicy gammon steak – great comfort food.

Tuscan kale and borlotti beans

2-3 good fistfuls of cavolo nero

200g borlotti beans

2 cloves garlic

1 teasp smoked paprika

Olive oil

Salt

Pepper

Rinse the beans and soak them in cold water for at least four hours. Drain, and put them in a large pan of cold water. Bring to the boil, and simmer, semi-covered, until the beans are just tender. Drain, return the beans to the pan and pour over about a tablespoonful of good olive oil. Toss the beans in the oil, cover and leave while you prepare the cavolo nero.

Put a large pan of water on to boil, adding a good thick pinch of salt. Wash the leaves well, stripping out any tough central stalks – you don’t have to be obsessive about this. Slice the greens thickly widthways. Add to the pan when the water is boiling and bring it back to the boil as quickly as possible. Boil for 2-3 minutes, then drain well, pressing out any liquid with the back of a wooden spoon.

In the cavolo nero pan, pour a dessertspoon of olive oil and heat gently. Chop the garlic cloves very finely and add to the oil. As soon as the garlic starts to sizzle, throw in the cavolo nero and toss well to distribute the garlic. Stir in the beans, and add the smoked paprika (or ordinary paprika if no smoked is available). Taste for seasoning and add salt and pepper if you think it needs it. Make sure it’s all piping hot and serve.
