Square foot gardening
Hi all, this is my second year of vegetable gardening. I had a fairly successful first year - so wish to get a 4ft by 4ft or similar small sized raised bed. I will divide it up into equal cells. I was hoping to plant a butternut squash and courgette at the back of it growing up trellis, and then have space for other plants such as carrots, lettuce, plum tomatoes etc.
The raised bed is not that high around 13cm, is the height important?
Any information or guidance would be much appreciated!
