Over the years in which climate change has been discussed in the media, there have been continual suggestions that it will be of benefit to gardeners – allowing us to grow fruit and vegetable crops that enjoy the continental climate, but fail to thrive in a traditional British summer. As those warm summer days have failed to materialise, and look increasing unlikely, I am eyeing up my new allotment with a view to planting crops that will enjoy our cool climate.
Spuds are a good choice, as potatoes don’t need a lot of sun to do well, but the possibility of warm, humid periods means blight is a big risk and I’m going to try growing resistant Sarpo varieties in place of old favourites.
Perennial veg and fruit are always good choices, as they don’t rely on one season’s weather to provide a crop. Rhubarb is an allotment staple that usually does well, and red and white currants need far less sun to fruit well than blackcurrants. Asparagus is designed to start growing in cool weather. Artichokes, such as Globe artichokes, Jerusalem artichokes and Chinese artichokes are usually worth the space they take up.
I’ve had success with courgettes and summer squash in a lacklustre summer, but good crops of fruit are not guaranteed. Tomatoes are tricky unless the sun comes out, but the smaller the fruit, the more likely they are to ripen. Sub-Arctic Plenty is a determinate, cherry tom variety that was bred to crop outdoors in Greenland, and I’ve found it reliably does so here as well.
Leafy veg love wetter weather, and if I can keep the slugs off then spinach and chard, cabbages and all of the Oriental leaf vegetables will keep me in greens for months. Leafy herbs like mint, coriander and parsley should also do well, but basil will be happier on the kitchen windowsill.
There’s no reason I have to stay on the beaten track, either, as there are more unusual species from around the world that will have no problem with this weather. Achocha, one of the Lost Crops of the Incas, is a climbing plant that romps away in cool summers and produces masses of fruit that can be used like green peppers. Oca, or New Zealand Yam, (another native of South America) is a pretty, clumping root crop. It doesn’t need a hot summer to crop well, although it does benefit from a long autumn and a mild frost or two before the big freeze begins.
Edible flowers are all the rage this year, and calendula and borage both self-seed quite happily in my garden, adding splashes of colour to borders and dinners throughout the summer. I’ll be introducing those to the allotment as well, and it wouldn’t be complete without a few nasturtiums, which seem to flower well regardless of the weather and have edible leaves to boot.
Every year is different, and each autumn it’s interesting to see what has done well and what faltered. What have been your big winners, in the cooler summers of recent years?
