Would you eat insects?

More and more these days, the media is full of stories of superfoods – usually fruits with high concentrations of antioxidants. The blueberry led the superfood charge, but has been left behind by newer and more exotic rivals, such as acai berries, goji berries and the yumberry.

Outside of the tropics, the only place you’re likely to see a cocoa tree (Theobroma cacao, the trees that give us chocolate) is in a heated greenhouse at the botanical gardens. They can be grown as house plants, and seeds germinate easily when they’re fresh, but their size, their requirement for heat and the fact that you need two plants for pollination means that they’re unlikely to bear fruit. And even if they did, the process of turning cocoa beans into chocolate is a long one.

In times past, blackberries were deliberately used as hedging plants, and their prickles make them a very good intruder deterrent if you have an open boundary. They have also been used in herbal medicine. Chewing blackberry leaves was said to soothe a toothache, and frozen blackberries are great for soothing a sore throat or a tickly cough.

It’s not the world’s best photo, because it’s taken with my camera phone, but here is my bookazine on the shelves in my local Tesco!

It’s hard to imagine anyone being more excited about eating lettuce than the three astronauts aboard the International Space Station (ISS) were yesterday, when they tucked into the first leaves of space-grown lettuce they’ve been allowed to eat. Despite having to sanitise the leaves first, with citric-acid-based, food-safe, antibacterial wipes (yummy!), they broke out the oil and vinegar and tucked in with gusto. They even thanked Mission Control and the scientists for giving them the opportunity to take part in this payload mission, and saved some veggies for the Russian cosmonauts who were outside on a spacewalk at harvest time.

Two researchers from the University of Central Florida – Kevin Cannon and Daniel Britt – have been looking at how a Martian colony might feed itself. Although NASA has been growing some food on the International Space Station, its goal is to supplement the vitamins and minerals in a standard astronaut diet and to improve crew morale – it’s not about making a space station, or a colony, self-sufficient.

I’m not the kind of person who creates a meal plan and shopping list every week, and then sticks to it religiously. I do like to have some idea of what we’re going to eat, however, as this cuts down on the number of nights when there’s nothing for dinner. Our current methodology is to fill the fridge and the freezer with things we eat regularly, and to eat them in rotation to avoid food waste. It’s a mix-and-match, ‘that will go nicely with this’ kind of thing, rarely looking more than 2 days ahead unless there’s a special event happening. It works for us, and we have very little waste.

Here in the UK it’s traditional to take a couple of weeks off work over the summer and head off to somewhere with better weather – or at least somewhere that you can get away from it all for a little while. It’s one of the ironies of life that this takes you away from the garden at a time when it really could use your help. If you have a gardening neighbour then you can rely on them to take care of your garden while you’re away, but if you don’t and don’t want to come home to dead plants, weeds and giant marrows then there are a few things you can do to prepare your garden for your absence.

The stinging nettle Urtica dioica is one of the easiest plants to identify – a quick brush past it and you’ll certainly know that you’ve found one! This tough perennial that can reproduce by seeds and by spreading roots is hard to eradicate from the garden, but in times past its virtues were far more valued than they are today.

I’ve always been fascinated by the Home Front, the enlistment of every man, woman and child in the British Isles in an effort to beat Hitler through food rationing, making do and mending, salvage, growing your own and basically making the most of scarce resources with elbow grease and endless ingenuity. I’ve just read Eggs or Anarchy by William Sitwell, a biography of Lord Woolton who was the Minister of Food for much of the Second World War. He was in charge of ensuring everyone got fed, and improving nutritional standards was one of his aims. It’s unusual to get the ‘behind-the-scenes’ view, and the political situation wasn’t as united as may appear from our rose-tinted histories.

A little while ago I was talking about the recent extended period in my life when, for a variety of reasons, I was unable to garden. As it happens, I have been reading The Resilient Gardener, by Carol Deppe, which is subtitled “Food production and self-reliance in uncertain times”.

The allotment is having to take care of itself for a while, as I’m concentrating on finishing my dissertation. It’s going down nature’s preferred route for taking care of unused soil, and covering itself in weeds. Come September I’m going to have my work cut out getting them under control….
