Oca and ulluco harvest

China Central Television has produced a short video showing the plant experiments growing on the Tiangong space station. The Shenzhou-16 crew has been in orbit for almost three months, and says their space vegetable garden has given a good lettuce harvest.

For my Masters dissertation last year I did some research into gardeners who choose to grow unusual edible crops. I settled on two species to investigate, achocha and oca. In the past I’ve written about how to grow achocha – it’s a nice, easy plant and in a temperate climate you should have no problems getting a significant yield. You may have more of a problem dealing with the glut….

It’s raining heavily today, so there’s no point even trying to go outside into the garden, but if there’s a plus point to such dreadful weather then it does – at least temporarily – make people aware of what’s under their feet. Soil tends to be forgotten until it turns into mud, or you squelch along through sodden grass, or watch priceless fertility washed down the drain. Weather like this shows us the importance of winter soil care, particularly keeping soil covered (even if all you have is weeds!) so that plant roots can hold it all together for you.

We’ve all been there. We’ve all read the marketing blurb for a shiny new plant variety, and decided that we had to have it. We may have been good, and waited for a few days, to be sure that we really had to have it, but we’ve all paid money for brand new plant varieties for the garden. And then we find out that they don’t quite live up to the hype. You don’t hear about ‘early adopters’ outside of the tech world, really, but that’s exactly what we are, and a certain amount of disappointment is inevitable.

Every month this year I’ve been trying to read one of the unread books on my shelf, and to then decide whether it gets to keep its spot or needs to be set free to find a new home. For June I chose Nature’s Wild Harvest by Eric Soothill and Michael J. Thomas. It was published in 1983, and has been sitting on my bookshelf for three years, since I bought it in our local secondhand bookshop (which only opens on Wednesdays).

Well, it’s the last day of National Gardening Week, and I hope you’ve been enjoying the vicarious harvests from my garden! I have enjoyed really focusing on what’s in season, and what we should be (and are!) harvesting and eating. It’s easy for me to forget that this garden is still very young, and it’s still maturing and I am still learning its quirks.

A couple of weeks ago, I was looking for some statistics about the average UK garden size, and I found some interesting ones. According to the 2015 media pack for the RHS The Garden magazine, a document that is aimed at attracting advertisers to the publication, the 380,000 RHS members the magazine is sent to have gardens that are 10 times larger than the UK average, covering over half an acre.

This is what the wild, self-seeded comfrey plant outside my front door looked like last week. It doesn’t look like that now, though, because I have cut it back and put the leaves to rot in one of my comfrey buckets (they have lids and taps). First, though, I had to empty out the last lot of comfrey liquid. I can’t remember when I made it – I don’t think it was last year, I think it must have been before that – and I harvested 3 litres of comfrey liquid from my pair of bucket. That’s certainly enough to keep my tomatoes and peppers happy this year!

Earlier this year I was absolutely horrified when the flat footed fence fitters trampled all over my wild garlic. It was just starting to leaf out, and I don’t know why the sudden garlic smell wafting up from their feet didn’t give them pause, but it didn’t!

On the weekend that we had Jus-Rol Cinnamon Swirls as our mid-gardening snack, I also hatched a plan to use up the last of the oca harvest. Oca is Oxalis tuberosa, mainly grown for its edible tubers, which were (are?) a staple crop in its homeland of the Andes. There they have a large number of different varieties, bred for different culinary uses. This far out of its normal range we have a much more limited choice, although there are people working on that. Oca tubers are a bit like potatoes and generally used in the same way, although their flavour is a little different.

This week is National Gardening Week, and the theme for 2019 is Edible Britain – a chance for gardeners across the country to show their love of home-grown produce.
