Jerusalem and Globe artichokes are part of my plan to grow as many perennial edibles as possible, providing my family with food year after year without my having to replant/re-seed.
As I mentioned when we unveiled our AtoZ Challenge themes, my life goal is to develop a food forest at home which provides 80-90% of our vegetables, herbs and fruit 12 months a year without making gardening a fulltime job /time-consuming/stressful /expensive activity.
I hope to reach that target by the summer of 2018.
Growing Jerusalem artichokes
Site selection: Site selection is critical when it comes to growing Jerusalem artichokes. Any tubers you leave in the ground when you harvest will bring forth another crop of artichokes, which is great if you want them perennially but irritating if your resources are limited and you want to use the site for something else.
So if you have a big garden, make sure you plant them in an area where you won't mind if they keep coming back. If your garden is small to tiny, plant them in big containers.
Also, Jerusalem artichokes grow very tall, which means that they can cast shade over some of your crops. So co-plant them with shade-loving vegetables.
Soil preparation: Jerusalem artichokes like composted, well-drained soil. I'm going to plant mine on a former rubbish dump. When I was growing up, the village did not have refuse removal. We dug a big hole in a corner near the kitchen and threw food wastes in there. Plastic and paper products we burnt every week or so.
The planting process: Like potatoes, Jerusalem artichokes are grown with tubers. You just put them around 10-15cm (4-6in) deep and 30 cm (12in) apart and water the site.
Caring for the plants: You don't have to water Jerusalem artichokes unless you are experiencing severe drought. I also read that they are not prone to disease either. How cool is that?
When the stems are around 30cm (12in) tall though, draw some soil around the plants to a depth of around 30cm 15cm (6in) to help stabilise them as they grow. When they've grown to a foot or so, mulch the area around the plants with grass clippings and rotting leaves to help them retain soil moisture.
Around midsummer, when your Jerusalem artichokes are around 1.5m (5ft), cut back the stems including flowerheads. This ensures that they are not rocked by the wind and you won't have to stake them either.
Harvesting Jerusalem artichokes: Begin harvesting your artichokes in late Autumn in cold areas and mid-winter in milder areas. To harvest, you dig them out with a fork much like you'd do with potatoes, making sure that you take out all the tubers if you're not planning to grow the plant there again.
Like potatoes, you can wash and dry the artichoke tubers and then store them in a cool area. They can also keep in the fridge for months.
A short tribute to Jacarandas
I also want to pay tribute to Jacaranda trees while I have a chance. Every year from October through December, jacaranda trees bloom in South Africa and Johannesburg, the city where I lived for over 20 years bursts with colour.
To give you perspective, Johannesburg is the largest man-made forest in the world, with at least 6 million trees counted by the City of Johannesburg municipality and thousands of these trees are jacarandas, resulting in a layer of purple lining street after street.
The photo below is of a street in my Johannesburg suburb, not too far from where I still have a house. I love going for long walks during this period. Somehow this profusion of colour always sings to me.
