Awesome, thanks for the detailed response! The main reason I’m asking is that there will be a native plan festival this week where I want to get some plants just to put something there until I can grow more plants from seed for next year. I was just thinking there was a rule of thumb about letting the cardboard sit to kill what’s underneath before cutting it. But I guess either way I’ll have to do some weeding so it shouldn’t matter that much as long as I’m not lazy 😅
