Nope everything they grow is dead and weeds haha.
I mean in general, if some things will grow for 3 months (whatever it is cabbage carrot tomato doesn’t matter) then those things is what I would plant maybe 3-4 weeks apart so it goes through the whole 3 months rather than coming all up at once?
I know tomato works different it keeps growing fruit over the season as do cucumbers and chilies etc.
Spinach etc I assume you just pick outer leaves and let centers keep going until it’s finished. So that as well you would just plant all at once….
Maybe it’s just root vegetables then… But onions keep for ages so you could just do them in chunks…
Maybe it is just carrots… *scratches head*
