My brother constructed the raised beds . Its prooving to be a real gem when it comes to WEEDING . All our raised beds are 2 meters x 1 meter. I find this size manageble and good for cultivating root vegetables as these need soft ground.
Do not grow Brussel sprouts and Winter cabbage in a raised bed as these need hard ground.
In November last year we planted onions and garlic in one bed and Early peas (Feltham First) in another raised bed.
These beds are ideal for organic gardening and you dont have to do hard digging.
