This is my first year gardening and I planted some peas a couple of weeks ago (from seedlings) . one of the plants already has two whiteflowers on it and I am thinking that a 6 or7" plant shouldnt be allowed to flower yet? Also I planted some mustard seeds and those things are huge already and taking over my herb patch...does anyone know how big mustard actually get? I will probally have to move them already. Thanks!
