I am new to gardening and growing veg.
Most of what I planted is doing well but I am wondering if there is something wrong with my red cabbage.The plants have developed large and healthy looking outer leaves but the centre where I presume the cabbage should form is tiny and shrivelled on all the plants. Is this normal and, if not, can they be rescued? They are taking up a lot of room so I would like to remove them and if they are not going to amount anything.
