Growing Onions Vertically On The Windowsill
One for the enthusiast

How nice would it be to just be able to pluck fresh green onions from the soil whenever you need them? Nothing beats fresh onions for your salads, dips or soup. But how can you ensure a supply of fresh onions at hand all the time?
Sure, onions are available all year round from the supermarket, but they are hardly fresh and there’s almost always no way to know for sure where they came from.
Gardeners of course will simply grow them but some simply have problems with available space.
I came across an image of spring onions grown vertically on the windowsill, using a common 5 Liter PBS bottle, which I thought was a practical, space-saving and green way to grow onions. I posted the image on our Facebook Page and a few people asked how it was done…
…and since I was curious myself, I did a bit of research and this is what I found:
FIRST, you need a planting vessel:
NEXT, you need to remove the neck of the bottle then cut holes around it. You can use a scissor or a heated metal tool to make the holes. Make sure the holes are just the right for the onion bulbs.
NEXT, fill the bottle with layers of onion sprouts and soil.
Keep adding layers until you reach the top of the container.
NEXT, water it…
