Advice on building a raised bed
Im new to gardening and have recently moved into a rented house with a big (and slightly overgrown) garden. I cant change the garden too much but I would like to grow my own veg so I thought I would put a raised bed at the bottom of the garden but have never done this sort of thing before so Im looking for some advice The area that Iv earmarked is paved (very uneven) with lots of weeds on it (to the point that we initially didn’t know there was paving underneath) which I’m in the process of clearing! Can I put a raised bad on top of paving? Can anyone suggest a good quality but cheap way to build a bed and how tall should it be (Im thinking at least 2ft if I build it on top of the paving and Im thinking of growing strawberries, peas, squashes and onions etc…). Also, what sort of soil should I put in it (can I use the multipurpose compost that I use for containers?). Any advice would be greatly appreciated!
