And the results are in…

An early harvest of Colleen

An early harvest of Colleen

This year I decided to keep a record of some of the crops that I harvested from the garden (not all of them, I’m not that much of a garden-geek). Really I wanted to demonstrate to myself that I am making a useful contribution to our food consumption, and to show that it is possible to grow a significant amount of food in a relatively small space. The two crops that I recorded were courgettes and potatoes. Since the potatoes were all dug up some weeks ago and the courgette plants have now been finished off by the cold weather, I have the full season’s results.

In total, from an area of approximately four square metres I harvested just over 12kg of courgettes. Of these 7.3kg were from ‘ordinary’ courgettes (two green bush and two Trieste White Cousa) and 4.8kg from three Costata Romanesco plants. We ate the majority of these over the summer, but some of them went into soups that are currently frozen for winter consumption.

The total harvest of potatoes was an impressive 41kg. They have been feeding us since about June and we still have quite a lot stored. We grew these in approximately five square metres of garden plus three dumpy bags* and one small growing sack. The most prolific variety in the dumpy bags was the first early variety Colleen which yielded just over 6.07kg from one dumpy bag filled with grass clippings. garden compost and shredded paper and planted with 9 tubers. In comparison, six tubers planted in a soil-filled raised bed gave us 5.73kg. The main crop varieties Milva and Mira did less well, only yielding 3.5kg from their dumpy bag (I mixed them together). Valor (a second early) did particularly well in the raised bed containing soil, yielding an astonishing 12.7kg  from 6 tubers.

All varieties of potato did better in soil in beds than in dumpy bags. I think this is actually related to water availability: we had a very dry summer and the vigorously growing potatoes in the dumpy bags wilted on numerous occasions even with daily watering, whilst those growing in the garden never wilted. Despite this limitation, the dumpy bags were a great success – they increased the growing space available and added significantly to our harvest. My favourite potato has to be Colleen – they grow really well and provide the first potatoes of the season, but I liked Valor too. I think these are the varieties we will focus on next year.

The Costata Romanesco courgettes are a favourite of Carol Deppe and she recommends using them for drying. This is something we didn’t get round to doing this year, but I will have a go at next year. The plants are big and start off as bushes, but then get to sprawling around. Whilst not prolific in terms of fruit, those they do grow can get really big but still remain very tasty (unlike marrows) and tender. However, I do like the more normal courgettes, especially for their joyful abundance and will continue to grow them every year.

All in all, it’s been an interesting experiment to weigh our crops. And what’s the most important thing I have learned? Next time make a proper recording sheet, because trying to decipher all those scribbled notes on several tatty sheets of paper is quite a challenge at the end of the season!

* I have been experimenting with growing in containers in a previously unused bit of space. There are several ‘waste of space’ posts if you are interested: here, here and here

The three sisters

There is a planting scheme known as the three sisters; it comprises corn, squash and beans.

I tried it out last year in my Waste of Space plot, but the weather was so disastrous that I had little success. This year, however, I am going to try again, but in my rubbish bed – a location where squash cultivation has been particularly successful in the past. The rubbish bed has been added to over the winter and spring: cardboard, shredded paper, grass clippings, chicken bedding, wood ash and spent compost from last year’s pots in the greenhouse. The chickens have given it a good stir up and added a bit of extra fertility and so it’s ready to be planted.

The idea behind the combination of the three species is that they use different resources and support each other. So, for example, the beans add nitrogen to the system which can be used by the other two species; and the squashes cover the ground, thus shading roots, reducing evaporation from the soil and suppressing weeds. In theory, the corn should provide a physical support for the beans, but I am going to use bean poles in case the pace of corn growth does not match that of the beans.

This guild of plants, as permaculturists call it (guild means something else to ecologists) seems to be particularly adapted to North American conditions, so a little tweaking is required to suit west Wales. First, I’m growing Flint Corn rather than Sweet Corn. This corn originates from Carol Deppe in Washington State… a place much more like west Wales in terms of rainfall and light levels than much of the US. It isn’t as sweet as sweet corn, but you can use it to make things like polenta, so it seems like it’s worth a go. My beans are runner beans rather than pole beans, but these do well (usually) in west Wales, so I’m sticking to what I know. And, finally, I’m using courgettes and squashes that I know to be successful in my garden.

I have to confess that, in the past, I have had limited success with this sort of polyculture planting of annuals. My perennials in the fruit cage seem to do well, but last year’s salad leaves did not seem any more productive than if I have planted them in the usual way rather than completely intermixed… but it was such a tough growing year that I have no idea whether this is really true*. Anyway, I’m going to give this mixed bed a go and see how productive it is. At least this year, thanks to the new segregation of vegetables and hens, I won’t be fighting to keep chickens out of the beans.

And today I also want to mention a brilliant local project that I am supporting: a buffalo dairy. After failing to raise enough funds via a crowd funding website, our small local buffalo farm have launched an appeal for funds via their blog… they have great incentives and I’m certainly looking forward to raw buffalo milk mozzarella from just up the road. Check out the rewards they are offering… there are some attractive offers, and it’s a cost-effective investment if you like this sort of cheese (lactase enzyme at the ready for me!).

* Note to self: actually collect some data on yields this year!
