I started working on the future outdoor enclosure plot today. This place used to be 3 raised veggie gardens for my kids but last year or 2 it's just been a Weed Garden. There was this huge weed with tons of little daisylike flower most of which have already gone to seed (meaning- I'm to expect babies of this weed all over the place in a Spring). Does anyone know what it is? In case my inquisitive babies decide to munch on it? Should I make sure every last seedling is gone ? the whole plant from a distance looks like Baby's Breath, the leave are ferny, thin and short green.
