Conkers and spiders and wonderful trees

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….

Back at the end of May, I picked up two bags of Sárpo Mira seed potatoes, discounted at the garden centre as it was past prime spud-planting time. When I went to GIY UK two months later, I still hadn’t found time to plant them.

When I woke up yesterday morning, it was misty. We’re approaching the middle of October, which is the usual time for the first frosts of autumn in my part of the UK. People in different areas are already reporting the arrival of the frosts on Twitter. This means it’s time for me to pop out into the garden and bring in my lemon tree (which I grew from a pip, several years ago). It has been enjoying the summer weather in the garden, but it’s only really hardy down to -10°C. I’ve nearly lost it a couple of times, and it has died right back to nothing, but somehow it always manages to come back.

If you’re currently tending lettuce plants, then you have something in common with the crew on board the International Space Station (ISS). They’re testing NASA’s new Vegetable Production System – affectionately known as ‘Veggie’. At 11.5 inches by 14.5 inches, Veggie is the largest plant growth chamber to have been blasted into space, and was developed by Orbital Technologies Corp.

Buying plants

I’d like to write more books. I enjoy writing and I have ideas and information that I want so share, and packaging it up neatly in a coherent volume is a bit different to just churning out blog posts. For one thing, it’s more permanent; I’ve sent copies of Jade Pearls and Alien Eyeballs to the British Library and to the five legal deposit libraries (Bodleian Library Oxford University, The Cambridge University Library, National Library of Scotland, National Library of Wales and Trinity College Dublin), and knowing that they have been preserved for posterity is not a small thing.

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.

Wimbledon fortnight coincides with the height of the strawberry season here in the UK and the humble strawberry becomes world-famous as tennis spectators tuck into strawberries and cream in front of the cameras. This year it even looks like they’ll be able to leave their raincoats at home!

I’m not a chemist, but I do find plant chemistry (and the links and patterns between different plants) to be a fascinating topic. Fortunately there are chemists out there who can bring these to our attention, and Compound Interest includes some great plant-related infographics amongst a wider spread of chemical topics.

One of the great joys of spring is seeing trees leaf out and bloom. They bring so much joy, and do so much for us, and yet are rarely valued as they should be. In particular, ancient trees are wondrous, magical things. Impressive and complex structures, they have lots of nooks and crannies in which wildlife can find a home. As fungi feed on the tree they provide food for woodland creatures, and a hollowed out trunk provides shelter. Although ancient trees are in the final stage of their life, and technically in decline, they have a lot to give, and can go on living for a long time, depending on the species.

I’m hoping to go and see The Martian soon, one of the few films to feature a botanist as the hero. Astronaut Mark Watney is one of the first humans to set foot on Mars, but accidentally gets left behind and has to survive on his own – and to do so he grows potatoes. He wouldn’t be the first person (or even population) to rely on potatoes for survival, but here on Earth there’s a slight snag. The potato (Solanum tuberosum) has an arch nemesis – late blight, caused by an organism called Phytophthora infestans. It cuts down both potatoes and tomatoes, and was the biological cause of the Irish Potato Famine in the 19th century.

The idea that we should be gardening without using peat is not a new one, at least here in the UK. I have a copy of ‘Gardening Without Peat’, published by Friends of the Earth in 1991. It explains that our exploitation of peat bogs is using up peat faster than it is being formed – we should consider it a non-renewable resource. The destruction of the peat bogs is causing a decline in biodiversity and allowing carbon dioxide to escape into the atmosphere to add to our climate woes.
