After moving house sixteen times, I’ve learned to adapt my gardens to all sorts of spaces – large and small. In this post, I’m sharing a list of plants I’ve found to grow well in containers plus the depth of soil they need.
If you have difficult soil like sand, clay or rocks; limited space or funds, then I suggest you try growing at least some of your food in containers – they offer loads of benefits.
“Growing your own veggies is the first step to self-sufficiency.” – Clive Blazey, The Diggers Club
In Fast Food! DIY Instant Veggie Garden: Part 1, I shared a quick way to grow in recycled polystyrene (Styrofoam) boxes.
I must confess I discovered just how productive these small space gardens could be, by accident …
Next thing, it was time to make dinner and I decided my little seedlings would have to wait till the next day to be planted! In our hot climate, I knew they’d fry outside so I gave them a little extra water and looking for a cool solution, popped them in the fridge to keep them fresh! I figured we keep veggies fresh in the fridge so why not seedlings?
It might have saved my plant babies, but you know what they say about “out of sight – out of mind”! … Next day, they were totally forgotten because they weren’t visible! By the third day I wondered what was in the newspaper in the fridge and unwrapped them, feeling a pang of guilt for my poor little seedlings still waiting for their new home. So out I went to find a place to put them in my garden.
In my haste to buy new seedlings, I hadn’t realised the garden bed needed far too much time spent on it before I could plant them. So I needed another temporary alternative! I spied the poly box and quickly filled it with my ready-to-go homemade potting mix.
Well, you can probably guess … life happened in the meantime … and that first poly box became the permanent home to a dozen very healthy lettuces and herbs by default! They were all very shallow rooted edibles that were light feeders. The herbs didn’t take up too much ‘personal space’ so it was a very efficient system for growing a high yield in a small box.
They say “old habits die hard” and in my case, although I have often intended to have a garden bed ready for seedling babies when they need planting, it isn’t always the case!
If you haven’t tried this yet, I’d encourage you to give it a go!

“Planting a garden with food potential is one of the most valuable things we can do.” – Isabell Shipard, Author
Mulch (grow your own and save money – fantastic solution for balconies and all gardens to save you buying in bulk if you give them regular ‘haircuts’ – just ‘chop & drop’ as mulch!):
Medicinals (handy for minor aches, pains, stings, burns etc):
- Aloe Vera & Lemon Balm (20cm/8in)
