Bizarrely, my Swift first earlies, which I planted in early April, have hardly grown. They popped up on time but are only about 6 inches tall and several have died/disappeared. They have been completely overtaken by Blue Edzell and PFA which were planted a month or so later.
They dont show any signs of flowering, and I am tempted to dig them all up and put something else in. Or is this being premature?!
