Making the most of planting space.

Please could you give me some advice on making the most of space in the garden. Sadly i have no pictures so i will try to explain what i would like to do.

Around the border of the garden we have a wall around 2ft high that is backfilled with soil up to the gravel board on the fence panel.
The gap between the wall and the panel is around 6" and the depth of the soil i would suggust is 1 to 2ft deep.
I would like to plant tomatoes, cucumbers and courgettes in this space and train them up canes that i have placed across the fence panel.
My concern is that the 6" width is to small to grow these plants in and may stunt there growth and crop. Any advice you can offer is most welcome. Thank you.

 

I reckon I've got about the same amount of planting space in my containers (potatoes not included), and I'm aiming to grow purple sprouting broccoli, garlic, radishes and tomatilloes (the latter when it's warm enough). And I'm about to shove 12 strawberry runners into a pot too!

My next door neighbour had several very successful tomato plants in tiny pots (probably 3-5 litre). But (this might be important), he and I have our vegetable containers on our sunny fire escapes. And neither of us have ever done cucumbers or courgettes before.

I'm sure the more experienced gardeners will be able to help more (and I'll be interested to hear their thoughts too). I suspect the roots will find a way to deal with a narrow area.

 

V G, I don`t see a problem with what you want to grow. The plants may not be able to root outwards to far,but they will compensate by growing downwards. Go for it, and enjoy the rewards.
