Planting Canada Goldenrod (or Maybe Bluestem Goldenrod) Together With New England Aster

Question

I have a one-acre hillside I wish to plant to aster and goldenrod for fall returning Monarchs and bees. What is the best mix of the two seeds for balanced growth? Do I need a 50-50 distribution or should I plant more of one than the other? The fact that the two plants grow well together does not mean insects feed equally on them. And, does one outlast the other producing nectar as you head into late fall?

Answer 1

I believe that starting with a 50/50 mix will be your best bet. No matter what you do, nature is going to establish the proper ratio over time. What you don't want is to start with what we, as humans, assume is a good ratio, only to lose the crop.
