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!
