Gardening in a small space means there’s never enough room for everything you want. I’ve begun to make more use of the vertical space, especially along the sunny fence as I was showing you in this previous post. During Spring and Summer, my indoor window ledges are also pressed into service as ‘gardening’ areas for herbs and salad leaves. I try to grow some food crops as well as flowers.
This year I’m experimenting with growing Spring Onions both outdoors and indoors. The variety is DT Brown’s classic, White Lisbon. The indoor Spring Onions are in an upcycled apple juice carton. I wasn’t sure if this would be deep enough for them to fully grow.

The idea initially was to pot them on into a deeper container but somehow time got eaten up by other things and the seedlings grew too large to be able to transplant them without damaging the roots. Hence, the Spring Onions are still growing in their apple juice carton on my kitchen window ledge, but they don’t seem to have suffered too much it seems. They’ve grown on well from sowing in early April and some are almost ready for harvesting now. As I was preparing this post, I noticed I’d sown 20 seeds and this has resulted in a dozen plants.

My first two pots of outdoor Spring Onions were first sown into a small ‘propagator’ (upcycled food packaging) and kept on the kitchen window ledge. When the seedlings showed, I transplanted them into upcycled milk cartons and then I moved them outdoors.

For the final sowing of Spring Onions at the end of April, I sowed another small batch of seeds directly into their upcycled milk carton pot and hung them outside straight away. The milk carton plant pots are just hung on the sunny fence with string. Keeping the jug handle on the milk carton plant pots is useful for tying them onto other supports, I’ve found. I’ve done this with the air-pruning plant pots I made from milk cartons to hang on my willow garden screens too.

All of the outdoor Spring Onions have grown on well, despite regular buffeting by the seemingly incessant wind this Spring and Summer. The White Lisbon Spring Onions have been easy enough to grow. Regular watering has been the only after-care needed.

I’ve been pleased to note that another benefit to my vertical gardening experiments has been … so far! 😉 … the plants seem to have stayed safe from the munching molluscs that share my yard – or perhaps they’ve just been too busy grazing on my Sweet Peas!
