There’s nothing worse after potting up your onion plants to see them all flopping about in their pots, very often leaning across each other. This is really as bad as it can get, because if the onions are going to be left to their own devices, they will soon be bent. This will inevitably happen low down on the stem of the plant, the very area which needs to be as upright as possible in order to ensure that later on, your onions will have good shape or, more importantly, good form.
