The growing season

Last weekend I went away to teach an Introduction to Ecology course at Karuna in Shropshire, which one of the participants is very kind about in her latest blog post.

Whilst it’s a lovely time to be teaching outdoors, it’s not the ideal time to leave the garden, so even after just five days, I returned to huge weeds (where did all that goose-grass appear from?) which really need to be dealt with. The benefit is that, on my return, I really noticed how much growth the food plants had achieved: ripe raspberries, runner beans at the top of their canes and huge courgette plants with female flowers blooming. Perhaps the most impressive plant is Costata Romanesco summer squash. I’m reluctant to call it a courgette, as it produces fruit the size of a marrow, but with tender skin and a good flavour. It is particularly loved by one of my gardening heroes, Carol Deppe, so it must be good (she does not bestow her praise lightly). The following photos carefully avoid showing the weeds… the vegetables pictured are so abundant that nothing else is getting a look in (now, that’s good permaculture design!):

And the results are in…

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!

Squashy

Last year Patrick, from Bifurcated Carrots, was kind enough to send me some seeds that he had obtained from Carol Deppe. These included flint corn, which is now growing in my four sisters bed, and several varieties of squash.

I love winter squash – people keep telling me that I ought to try the variety ‘crown prince’, but somehow I have never got round to it. The most successful one I have grown here on the west coast of Wales is Boston – which I get from the Real Seed Catalogue. However, I was excited to have some different varieties to have a go with, particularly since Carol Deppe is in Oregon… another rather wet and dull part of the world with a relatively short growing season (at least as far as squash are concerned).

Anyway, I planted the seeds with great glee and was delighted that almost all of them germinated and started growing into robust plants. I had more than I needed, so passed some onto my friend Katy, who had a space in her garden and wanted some winter squash. Since then I have been watching mine grow… I was sure that I had labelled all of them when I planted them out, but one or two seem to now be anonymous; never mind, I will be able to match then to pictures on the internet, I’m sure.

However, I was happily inspecting the abundance the other day when it dawned on me that one of the varieties – Costata Romanesco – looked much more like a huge courgette (zucchini) than a winter squash. So, I dug out the packets and, sure enough, it’s a summer squash! I got out my copy of The resilient gardener by Carol Deppe and discovered that this variety can grow up to three or four feet long… although she recommends harvesting it before that. She claims that it’s very flavoursome (she hardly has a good word to say about courgettes on this matter) and can be dried for use over the winter in stews, soups etc. So now I’m even more excited about the prospect of a tasty and storable summer squash.

Just to test it out, I harvested one for dinner last night – only about 9 inches long, so a mere baby. I fried it in olive oil, with a little chopped garlic, straight out of the garden and it was, indeed, delicious. Another good characteristic of this variety is that it is dense and has a relatively low water content , unlike those horrible watery marrows that some people grow. This quality means that it is good for frying and should also be great for drying.

So: thanks to Patrick for the seeds; Linda – I will need to take you up on that offer to borrow your dehydrator later in the season; and Katy – some of those winter squashes I gave you are summer ones!
