I am toughening up though, cosmos are definitely coming out as soon as they show their first little leaves. I know it has a nice flower but it is weedy and a nuisance. Especially in the vegetable garden.
Another prolific seeder that I let go is borage. Yesterday I removed a heap from the paths in the vegetable garden but left these ones alone. The bees are loving them right now so they can stay for now at least. Until I need the space for tomatoes.
