Filling up raised bed
I was thinking of removing flagstones from an area to make room for a raised bed. So the raised bed would be 1330mm (W) x 1330mm (L) with height of 300mm
I already have some store bought topsoil, compost and some homemade compost to fill it up.
I would appreciate advise on few things please
- what should be the ratio of topsoil and compost?
- Also do I need to mix horticultural grit as well. And what should be the ratio that I need to add with topsoil and compost
- And presumably I should mix them all together and fill up the raised bed.
I mostly plan on growing mainly leafy greens like Kale, Swiss chard, mustard in the raised bed. And possibly some sprouting broccoli and green beans in the future.
As you can tell from the questions I’m asking that I’m new to raised beds and having searched the internet one gets different views. So thought best to post it here for getting good advise from experienced gardeners.
Many thanks in advance
