I’m new to gardening. I went mad on buying seeds, but the beds aren’t massive. They’re 110 x 90 each. I’m not sure whether to just grow one thing per bed, or do a mix per bed? I will be growing tomato’s and potato’s in a sack so that’s not an issue. I could also potentially dig a vegetable patch from out the ground so not sure which would go in the ground or raised beds or does it not matter?
