Last year these bulbs were planted and a single stem grew. The plants were nice and neat.
This year they all are sprouting with 5+ stems and they are overtaking the area, one even grew under and through my fence no idea how to dig it up without damaging the fence and bulb.
Are new bulbs forming on the original bulb that causes new growth? I've never dug up lily bulbs and I'm not sure when or how to do this without killing it.
