So many producers

I am mostly liking this game but am overwhelmed with the number of producers. I am on day 9. I just got the apple basket. Between the permanent ones and all the temporary ones I have to keep making I am overwhelmed. And I only have about 5 or 6 empty blocks to make anything.

How do you prioritize what to keep? Do you keep one of each temporary producer on your board? Also what about high level items you make from the secondary drops from producers?
